Auto Rendering Feature for DeviceLinks

One of the most difficult decisions in setting up a DeviceLink profile is to decide which rendering options to choose from the large list of options in CoPrA for a given task. Therefore we have implemented a new Mode drop-down menu (in the Rendering section of the DeviceLink module) that allows you to select between three typical use cases and a Custom mode.

Copra 7 auto rendering feature for device links

  • Close Match: A typical use case is for achieving the closest possible match between two color spaces, e.g. to achieve a match similar to a proof but without paper simulation and avoiding washed out shadows. An example would be the reproduction of ISO coated V2 on a digital printing machine so that both prints should look the same.
  • Another typical use case is a rather more colorful but still faithful rendering of a color space on a different printer. For example, a campaign prepared for ISO coated V2 but rendered on a large format inkjet printer. This use case can be further subdivided into either a paper relative rendering (e.g. without consideration of the paper tone - Automatic Paper Relative) or the consideration of the paper tone (Automatic Paper Absolute).

CoPra7 Auto Rendering Option

  • If one of the three Mode options is selected, the two drop-down menus for the rendering methods are preselected with the right options, and the best fitting Merge slider setting is calculated. In addition, the Advanced Rendering Options such as Lightness and/or Chroma are calculated, too. All options are grayed out, so the user just needs to select one of the Modes.
  • Custom gives full control to the user, enabling him to define all settings himself, as with CoPrA 6.

Note: The automatic works best if the target color space has a larger or similar gamut as the source profile.

Updated Profiling Settings

The profiling settings - also called presets - are a great starting point for Printer and DeviceLink profiling. This is most noticeable in the updated DeviceLink module where we have included the new automatic rendering feature. In addition, we have added presets, e.g. for Multicolor-to-Multicolor DeviceLinks, and for printer and DeviceLink profiling with white ink.

New Rendering Option Minimum Compression (Paper Relative)

In earlier versions of CoPrA we had already a Minimum Compression rendering method which has now been renamed to Minimum Compression (Paper Absolute). As the name suggests it minimally adjusts the white and black points only while the rest of the color space is treated more like an absolute colorimetric rendering. What was missing was a similar rendering method that works close to relative colorimetric - voilà the new Minimum Compression (Paper Relative).

Copra7 Minimum Compression

Side note: We have removed the Dynamic Compression rendering method which was available for DeviceLink profiling only. It did not provide much of a difference to the other rendering methods Blackpoint Compensation or Standard Compression and therefore was regarded as obsolete.

Additional Rendering Merge options for DeviceLinks

Earlier versions of CoPrA already provided the option to Merge the advanced ColorLogic rendering methods, e.g. Standard Compression merged with Absolute Compression. However, until now it was not possible to merge the four standard ICC rendering methods or a ColorLogic rendering method with one of the four standard ICC rendering methods. This is now possible, giving the user more flexibility for color rendering with DeviceLinks.

CoPra7 Additional Rendering Merge

Note: Merging is recommended among Relative Colorimetric, Absolute Colorimetric, Blackpoint Compensation and any ColorLogic rendering intent. However, merging between Perceptual rendering and other rendering intents is not recommended for 3rd party profiles.

Recent Files feature

With a right-click on the respective Load button or the small down arrow button of the profile chooser in the individual modules of the application, you can select the most recently added data (measurement data, created ICC profiles, images, etc.) so that you can easily re-select these data without having to search for them in various subfolders. This makes it easier to set up CoPrA, for example, if you have created a printer profile and immediately wanted to use this profile as a source or target profile in the DeviceLink module. This productivity feature will be extended to all ColorLogic applications so that data exchange will work across all the applications.

CoPra7 Recent Files Feature

Note: While holding the CMD key and clicking an entry in the Recent Files list, the file and its position on your computer will be highlighted in a pop-up folder.

Notification handling

Similar to ZePrA (Troubleshooting) a notification handler has been added in CoPrA that allows multiple messages to be displayed. This avoids notifications from overlapping each other and moves out of sight. If more than one notification or warning is available, this is shown in the icons with the number of warnings. When clicking on the icon or the warning text, all warnings are shown.

CoPra7 Notification Handling

Multicolor Mode Preserve Color Properties for DeviceLinks

Typically, users of CMYK-to-CMYK DeviceLinks apply the Black Generation feature Preserve separation in combination with Exceptions. This allows you to retain pure colors and the separation characteristics of the source. In order to provide a similar functionality for Multicolor-to-Multicolor DeviceLinks, we introduced a Multicolor Mode called Preserve Color Properties already in CoPrA 4.

CoPra7 Multicolor Mode Preserve Color Properties for Devicelinks

However, this mode had the limitation that the source and target color spaces must have the same amount of channels and the same channel names. So far, this mode did not work if the number of channels in the source and target profiles was different, for example for 6 to 7 color DeviceLinks, or for channels that differed in hue or name. This has now changed fundamentally with CoPrA 7 as all types of Multicolor-to-Multicolor combinations can be combined while preserving the color characteristics. This enables users to ensure that, for example, their Orange channel stays Orange or Orange with Magenta combinations are retained. CoPrA will automatically map channels that are similar in hue even if the channel names or the channel order differ between source and target profiles. If single channels do not match between source and target profiles but other channels are, such as Blue and Violett when combining a CMYKOB with a CMYKOGV profile, the Orange channel will be retained but the Blue will be recalculated using Violet and using a mixture of the other primaries to match the Blue original colors.

Note: You will find a new preset under Settings called Print to Print - Preserve Color Properties that selects the appropriate Multicolor Mode and all other settings for you.

Profile Manager improvements

The Profile Manager introduces several new features.

  1. The search for profiles can be performed for various Profile Types in the Profile Filter section. This allows the combination of the Search for feature for file names with a selected Profile Type for better search results.
  2. The Gamut tab for printer profiles allows you to load sample data such as spot colors from various sources such as CXF, CGATS TXT, or ACO files and others. Select 3D and move your cursor over the color patches to highlight them and to display their name, Lab value and their deltaE to the gamut border of the profile. Note: The deltaE is only appropriate for the Absolute Colorimetric Rendering Intent and will not be shown for other rendering intents.
  3. While right-clicking on a DeviceLink profile, the embedded source and target ICC printer profiles can be extracted using the Install embedded profiles option (if embedded profiles are present). This is useful if you have been sent a DeviceLink profile and the required printer profiles are not available on your system.
  4. For Multicolor DeviceLink profiles we display the curves for both color combinations in the profile report and have added images for color rendering checks.

CoPra7 Profile Manager Improvements

Printer and DeviceLink Profiles with white ink on black substrates

For color managed color prints on black substrates, such as textiles, white ink must be used first and colors must be applied on top of the white ink to obtain colorful graphics. If white inks are used for the separation, it would be beneficial to also use the back substrate for the black separation. However, profiling with white ink on black substrates was not available in CoPrA so far. Now, we introduce support for printing with White and 3 or 4 primary colors such as CMY or CMYK or any other primaries with or without Black. Our technology uses White ink for the separation. To create profiles with White, special test charts are required, which can be found in the test charts subfolder Special for the two cases CMY+White_on_Black and CMYK+White_on_Black.

How does it work?

  1. If measurement data are loaded in the New Printer Profile module that consists for example of CMYK and White, CoPrA recognizes it as a special case and a dialog appears asking whether CoPrA should preselect the required profiling Setting.
    CoPra7 New Printer Profile
  2. Select Yes and the appropriate preset is selected.
  3. Once the appropriate Multicolor Mode - in this case the new CMYK+White mode - has been selected all other Color Generation controls are disabled. There is no change or manual editing intended in this section. CoPra7 Color Generation
  4. The overall TAC can be reduced in the Black Point and TAC section.
  5. You may change the Perceptual Rendering, if required, in the General tab.
  6. Click Next to define the profile name and Save the ICC profile.
  7. Use the profile in your image editing and design application. Please be aware that the resulting ICC profile is a Multicolor profile, e.g. a 5CLR profile in case of CMYK+White and a 4CLR profile in case of CMY+White.

Observer choice for Printer Profiling

The Viewing Condition can be changed by the user in the General tab of the Printer Profiling module. The default setting for ICC profiles is D50 and 2 degrees standard observer. However, in some industries such as textile printing the viewing condition is D65 and 10 degrees standard observer. With CoPrA 7 users can change the Observer to 10 Degrees if required, provided that spectral data has been loaded for the measured test chart.

TAC editing for 2 or 3 channel profiles

For 3 color combinations such as CMY and even for 2 color combinations, there is a need to control TAC independently for color concerns such as ink bleeding on difficult materials. An automatic TAC control of a 3C profile will usually result in a higher ink load than some materials can tolerate, and 3C printing is likely to be employed in industrial printing processes such as textile, ceramics and others, where TAC must be kept low—often under 200%. Therefore, in CoPrA 7 we now introduced the ability to control the TAC for printer and DeviceLink profiles with 3 and 2 color channels.

CoPra7 TAC editing for 2 or 3 channel profiles

Another improvement for 2 and 3 color DeviceLink profiles is that we can exclude channels now, too.

CoPra7 DeviceLink exclude channels

DeviceLink Iteration improvements

The Iteration DeviceLink module is a great feature to get the best possible match for proofing. Proofing uses absolute colorimetric rendering without color exceptions. However, in digital production printing, perceptual rendering methods and color exceptions are used to keep colors pure. Nevertheless, there might be an interest to optimize the colors by iteration measurements.

It is not always recommended to do so, especially as out-of-gamut colors cannot be optimized. In CoPrA 7 it is now possible to iterate data for production printing while retaining exceptions during iteration. It recognizes exceptions and rendering settings from the selected reference DeviceLink profile and retains them but only if the selected DeviceLink is a ColorLogic profile. A checkbox will be shown in the dialog making the user aware that there are exceptions used. By default, the checkbox is enabled but the user may disable it.

CoPra7 DeviceLink Iteration Improvements

Furthermore, the layout of the iteration window now corresponds to that of the other CoPrA profiling modules. For example, the Back and Next buttons and a dedicated Save dialog have been added. Next takes the user now to the typical Save dialog where the profile Name, Size, embedding of source and target profiles and the creation of a profile report can be specified.

The Default Template for the profile naming uses an option that adds the number of iterations to each iterated DeviceLink. It is recommended to use the Auto Size option because size matters for iteration. The automation will make sure to always use the highest precision when creating the iterated DeviceLink.

6.0.3 27 May 2020

Bug fixes and improvements

  • DeviceLink Profiling: Fixed problems with Automatic Exceptions for Gray/Duplex/Triplex when using Multicolor target profiles.
  • ColorAnt updated to the new version ColorAnt 6.1 featuring the updated Measure Tool 3.1

6.0.2 4 May 2020

Bug fixes and improvements

  • The 100% Black and Gray exceptions in DeviceLink profiles now work correctly when converting to a black point using Multicolor.
  • In some cases (mostly in virtual machines) under Windows the application could hang after starting during the graphics library initialization process. This has been fixed and the startup process now runs correctly.
  • Prevent the use of unsupported languages in PDF reports by switching to english in such cases.
  • Some entrys (of the Signature type) such as Manufacturer in the Profile Manager weren’t shown in a readable format which prevented the search for these entries. This has been fixed and the search works again.
  • Fixed a problem in the DeviceLink module with adopting the correct Multicolor mode when importing settings from a profile.

6.0.1 5 March 2020

Bug fixes and improvements

Several improvements have been made in the Image Conversion dialog:

  • A minor cosmetic correction has been made under macOS so that the dialog no longer jumps when switching between the options Save Image and Use Layer.
  • The checkboxes Embed target profile and Convert to Lab now also check whether profiles are available or have been deleted. In case they are not available he checkboxes are greyed out accordingly.
  • The Stop button that appeared instead of the Save button when converting a file had no function and has been removed.

CoPrA 6.0.1 screenshot showing the removed "stop" button

  • In the Linearization module it is no longer possible to load unsupported color spaces with 1 or 2 channels or RGB via the Measure Tool. Only CMY, 3-channel, CMYK and multicolor color spaces are supported for linearization.
  • The buttons for OK and Cancel in the dialog that appears when a profile report should be overwritten were swapped under macOS. This has been fixed.
  • In the SaveInk module, the two default settings for TAC reduction (TAC-Limit220 and TAC-Limit300) have been adjusted so that less black is used.
  • A new information message has been added if the black channel is switched off and on again under Used Channels during Printer and/or DeviceLink Profiling. However, since the black channel turned off affects the setting under Maximum Black and this is reduced to zero, this setting will be retained when re-activating the black channel. The message The black channel is reactivated. Check and, if necessary, change the setting for Maximum Black under Black Point and TAC should remind the user to set the desired maximum black again.

CoPrA 6.0.1 screenshot showing the new information message that shows when the Black channel is turned off but still on in Used Channels

  • In the profile report of multicolor to multicolor DeviceLink profiles, the Multicolor Mode Preserve Color Properties used in the profile is now displayed correctly.
  • The two checkboxes Pure Black and Pure Gray are now available again for RGB printer profiles and are no longer grayed out.

CoPrA 6.0.1 screenshot showing the now available checkboxes for Pure Black and Pure Grey while RGB profiling

  • In the printer profile, the status of the two checkboxes Pure Black and Pure Gray as well as Used Channels is now correctly checked when switching the black channel on and off. In the previous version, the checkboxes remained grayed out even though the black channel was switched on again.
  • CoPrA stores the original and corrected measurements in separate tags (TARG and TARG2) in printer profiles created in the New Printer Profile and Update Profile modules. Corrected measured values are created when Measurement correction and/or Brightener correction has been activated. In version 6.0.1 it has now been corrected that in the Update Profile module two tags with the same measurement data are no longer saved, if the two checkboxes for the corrections have not been activated at all.
  • The displayed gamut volumes in the Gamut dialog of the Profile Manager and in the printer profile report now match. (Ticket #191649)
  • The incorrect error message that occurred when the Measure Tool was opened from CoPrA without a loaded measurement or reference file has been corrected. The Measure Tool now opens without error message and the desired reference file for measuring the test chart must be selected there.
  • The index error that occurred when transferring measured values from Measure Tool to CoPrA has been fixed. If the dialog for selecting the measurement condition has been closed from the user without selecting one condition, no error message is displayed anymore.
  • The Iteration module can now also be tested with a demo license. Until now this was not possible. (Ticket #191542)
  • In the Linearization module, the Default and Flexo Linearization presets have been updated. Both presets now also use the automatic channel limitation. If the channels are not sufficiently differentiated, this leads to a reduction of the individual color channels depending on the loaded measured values and thus to a better linearization.

CoPrA 6.0.1 screenshot showing the Default linearization setting with its new preset

  • The DeviceLink settings saved in RGB-to-RGB and RGB-to-Multicolor profiles are now correctly loaded and displayed in CoPrA again. This was previously incorrect.
    Note: The settings from all CoPrA profiles can be loaded by drag&drop onto the Settings drop-down menu.
  • During DeviceLink creation, the 100% Black exception did not work in conjunction with the Relative Colorimetric rendering intent and certain Black Control Range settings. This has been fixed. (Ticket #201823)
  • When creating DeviceLinks with multicolor color spaces, the calculation of the exception Border Clipping has been improved. However, due to the use of Look-Up Tables (LUTs), there are still transition areas where small percentages below 1% may appear. (Ticket #201787)

SaveInk for Multicolor

Users of the SaveInk module who also have a Multicolor license will benefit from the extension of the SaveInk module to create SaveInk DeviceLink profiles based on Multicolor profiles. Previous versions of CoPrA allowed only the creation of CMYK SaveInk profiles.

Note: ZePrA 7 supports SaveInk Multicolor DeviceLinks. Besides ZePrA, not many workflow tools are capable of processing a 7CLR-2-7CLR DeviceLink, for example.

SaveInk for Multicolor

For Multicolor profiles to be used as SaveInk profiles, a black channel must be present and it must be the fourth channel. Profiles that do not follow those rules can not be selected.

Note: For Multicolor profiles the exceptions to preserve skin tones and custom exceptions are not available.

DeviceLink Iteration

A new Iteration tool has been added to DeviceLink profiling. It allows to improve an existing DeviceLink profile based on a printed and measured test chart and requires a DeviceLink license. Even DeviceLinks with Multicolor color spaces can be optimized (additionally requires a Multicolor license).

CoPrA 6 Sidebar menu Iterate module

An existing CoPrA DeviceLink profile can be optimized based on measured color values by using a test chart of your choice (can be created with ColorAnt/Custom Chart). The test chart needs to be converted using the original DeviceLink profile and printed on the target printer. The measured color values are then used to improve the conversion in order to achieve lower color differences and a more accurate reproduction of the source color space. Iteration is therefore particularly useful in proofing situations with absolute or relative colorimetric rendering intents. Perceptive rendering intents can also be used as a special feature of DeviceLink iteration in CoPrA. The iteration calculates a new DeviceLink profile based on the original DeviceLink profile and the measured values. The new profile can be reinserted for iteration until the desired result is achieved.

Use the DeviceLink Iteration as follows:

  1. Select the DLP that you would like to improve
  2. Print a small profiling test chart (can be created with the Custom Chart tool in ColorAnt) on your printer via the DLP.
  3. Measure the chart and load the measurement data in the dialog
  4. Click on Save to calculate the iterated profile.

Extended Image Conversion features

The goal of the Image Conversion tool is to convert pixel based files for profile evaluations, e.g. while evaluating a demo version of CoPrA or to figure out which profile settings provide the best color rendering. This has been improved and extended. The entire dialog has been revamped to enlarge the preview of the loaded image shown on the right side of the dialog. In addition more options for converting to Lab are added and conversions can be saved in piled layers in one file to better check different color conversions in Photoshop.

CoPrA 6 Image Conversion Save Image window

On the left of the dialog there are three sections

In the first section you can load the image file to be converted. An embedded profile will be shown below the path to the image. Beside the path to the image a small icon represents the color space of the image.
Note that the Image Conversion tool does not support retaining Photoshop layers or transparencies. Nonetheless image files such as Photoshop PSD and TIFF files with layers or transparencies will be correctly converted, however, only the compatibility layer will be color converted while additional layers and transparencies are removed.

The second section allows to load source and target ICC or DeviceLink profiles. If a target profile is available it can be embedded in the converted file. This is true for DeviceLink profiles and the linked target profile used in that DeviceLink, too. The Convert to Lab option is useful to compare images with different target color spaces or to evaluate the color appearance of color conversions with Multicolor profiles. The latter is a nice addition to the Image Conversion tool as Photoshop does not allow to preview Multicolor images correctly and does not allow to apply conversion from Multicolor to Lab. In case the Convert to Lab checkbox is enabled an additional checkbox to enable Paper White Simulation can be enabled, too. If that checkbox is enabled the conversion to Lab uses the absolute colorimetric rendering intent, if disabled it is using the relative colorimetric rendering intent.

The third section contains a Mode switch. Your can either save the converted image using the Save Image mode, or, when switching to Use Layer, you can add a layer with the converted image in PSD file format. After a first conversion the same original image can be converted again with different profiles, and again, the resulting file can be placed as a layer on top of the previously converted image. With such a PSD file you can switch between the layers in Photoshop to evaluate the quality of the conversions. The layers names contain the profiles that have been used for better identification.

CoPrA 6 Image conversion Mode switch

Avoid Dot-on-Dot in Multicolor separations

When printing with gamut extending process colors such as CMYK+Orange+Green+Violet/Blue in traditional AM screening, the process colors Violet or Blue are often put on the same screening angle as Black. This can result in so called Dot-on-Dot issues leading to color and lightness variances. However, avoiding Black and Violet/Blue color combinations in separations would reduce the available gamut considerably and would also prevent dark bluish spot colors from being reproduced faithfully. Therefore when the Avoid Dot-on-Dot feature is enabled the separation will use more of the CMY colors instead of Black when combining with Violet/Blue.

CoPrA 6 Avoid Dot-on-Dot checkbox

The Avoid Dot-on-Dot feature is available in the Printer Profiling and DeviceLink Profiling modules.
Note that other color combinations using the same AM screening angles such as Cyan and Orange or Magenta and Green will not be touched by this feature because those combinations are rarely used in separations anyway.

Ink Limiting function for Linearization DeviceLinks

Ink limiting during linearization is necessary if ink channels are saturated and do not provide sufficient differentiation between the individual color values at higher ink densities. This is typically done by printing a step wedge and then visually determining the percentage up to which a good differentiation exists. The ink channel is then limited at this value. We have added an automatic channel limit function that does exactly this based on the saturation values of the measurements. This function has been added to the two Calculation Modes ColorLogic Default and Linearization according to ISO20654.

CoPrA 6 Linearization Calculation Mode window

Note: For the G7 mode the channel limit function has not been made available as this would contradict the G7 linearization methodology. Ink limiting should be done before applying G7.

Additional Linearization output formats supported

The final window of the Linearization module provides two new checkboxes to save the linearization curves either as Photoshop ACV files or as XML files according to the format definitions in ISO 18620:2016. Files, saved in the Adobe Photoshop Curve format (ACV) by CoPrA can be imported in Photoshop and applied to images. This way linearization curves calculated by CoPrA, such as G7 or ISO 20654 (SCTV) curves, can be used in Photoshop, too.

ISO 18620:2016 specifies a simple extensible XML format for the exchange of tone adjustment curves between applications including but not limited to color management, calibration and raster image processor systems. Some RIPs such as Esko Colorpilot support this format which allows to import and use the high quality curves generated by CoPrA.

The curves are saved with the same name as the ICC profile in the User/Documents/CoPrA/Linearization folder.

CoPrA 6 Additional Linearization output formats

The Size chooser has two options small and large which affect the number of data points saved in the ACV and XML formats. Small creates 11 points for ACV and XML while large creates the full flavoured 51 points for XML and 16 for ACV. The size does not affect the ICC DeviceLink profile created because it will always use the highest precision.

In addition, in Profile Manager there are new options added to the context menu to create ACV or XML curves from existing Linearization DeviceLink profiles.

Profile naming options and templates

A new Templates option has been added in addition to the Profile Name section. When clicking, the Automatically generate file names window opens. Here you can select and combine name components that are specific to each profile module from a list of options and save them as a custom template. The last selected template is used for all new profiles created, so that the naming of profiles can be automated.

CoPrA 6 Naming template

Available naming options are date, date and time, measurement data file name, source and target profiles, name of the current preset and others. The option selected in the drop-down menu can be added at a user-defined position (the position is chosen with the mouse pointer) in the Template. The Example section below shows how the name will actually look like. Beside the naming options user defined text can be added at any position in the Template section.

Protected Mode

The new Protected Mode available under Preferences allows to lock and protect all custom settings. If activated – with or without a password – changing a selected profiling Setting is denied. This feature proves to be practical if multiple operators in an organization are creating profiles and only a defined set of settings should be used instead of every operator using his own settings. Once the protected mode is activated options in the Preferences are disabled and importing and exporting of settings is denied.

CoPrA 6 Preferences Protected Mode

If you need stricter permissions, the Protected Mode can be used with a password. Enter a secure password and confirm by entering it a second time. If a password has been set, it must be entered each time the protected mode is to be deactivated. To remove or change the password, click Reset Password.

Productivity improvements

  • The new Black Generation mode Target Profile with ColorLogic Gamut Mapping is now availed in the DeviceLink module. In addition to the already existing mode Target Profile which disables all settings the new mode allows to edit them when clicking the Modify button. This can often come in handy as it allows to start with the existing settings of the target profile and then modify them to your needs.
    CoPrA 6 Black Generation Target Profile
  • For Multicolor target profiles in the DeviceLink module there is a new Multicolor Mode: Use Settings of the Target Profile. If the Multicolor profile is a CoPrA printer profile this mode will use the mode that has been selected during printer profile creation. In brackets the mode used will be shown. This has the advantage that it is immediately clear which mode was used and is to be used. For non CoPrA Multicolor profiles the Strong Multicolor Mode will be used.
    CoPrA 6 Multicolor Mode
  • A new Default DeltaE Method selection (dE76 or dE2000) for profile reports can be selected in the Preferences.
  • Support of up to 9 channels for DeviceLink creation. Previous versions of CoPrA supported up to 7 channels.
  • Improved black point curve and values visualization in Multicolor modes for special inks.
  • Improved interaction between ColorAnt and CoPrA when using multiple measurement conditions.
  • Additional Black Point Calculation option called Darkest for maximum density/lowest L*.
    CoPrA 6 Darkest Black Point
  • In the CoPrA Preferences there is a new option to share CoPrA profiling settings with ZePrA via a shared folder. This is the new and from now on only way to share settings between CoPrA 6 (and higher) and ZePrA. It has the advantage that CoPrA and ZePrA do not need to be installed on the same computer any more. The folder must simply be shared by both applications ZePrA and CoPrA via the network or a shared folder or via the cloud.
    CoPrA 6 Preferences Share With ZePrA

    Note: If the checkbox is enabled and the Preferences dialog closed with OK an information message will appear asking the user if all shared presets should now be copied to the defined Auto-Import Folder.
  • In Profile Manager there is a new tab to leave Notes for a selected profile. Those notes can then be used as a filter in the Search feature. For example you might write the name of a customer as a note in a bunch of profiles you have created for a project for that customer. With the Search for option set to Notes you simply can enter that name and all profiles with that note will be listed.
    CoPrA 6 Profile Manager Notes
  • The Profile Reports have been enhanced in several places. There is a new Color Generation section added to each profile type which allows to identify the settings that have been used during the creation of the profile. The reprofiler report of the Update Profile module now incorporates the device color values of the selected test chart in addition to the Lab data which makes it easier to identify the color values. In the General Information section of the report useful information about the size of the profile and the version number of the used CrossXColor profiling engine has been added. The DeviceLink profile reports show more curves for secondaries now.

5.0.1 19 March 2019

Bug fixes and improvements

  • The Printer Profiling and DeviceLink Profiling modules smoothness of the gray balance for some data has been improved. This can be recognized in the profile report when comparing profiles between version 5.0.1 and previous versions. (Ticket #180922)
  • In the Printer Profiling and DeviceLink Profiling modules the Black Point calculation has been improved. This improvement avoids strong spreading of the CMY components in the black point which may lead to a slightly less neutral (e.g. a*/b* not equal to 0) black point compared to previous versions but better printability.
  • While improving the Black Point Calculation some issues have been fixed regarding the displayed device and/or Lab values for the calculated black point in the user interface of the Printer Profiling and DeviceLink Profiling modules. What is now shown as being the black point in the user interface will with the exception of the special ink Multicolor modes actually be used in the profile.
    Note: With rare special data sets some discrepancies occurred with previous versions.
  • In the Printer Profiling and DeviceLink Profiling modules when disabling a channel under Used Channels the appropriate channel gets an X icon and will be disabled in combination with an X icon in the Black Point and TAC section, too.

CoPrA 5.0.1 - Used Channels

  • In the Image Conversion tool TIFF images with Lab color space are supported now.
  • Errors during loading of TIFF files in the Image Conversion tool have been fixed. (Ticket #180974)
  • Channel names in Multicolor TIFF and PSD files generated by the Image Conversion tool do not contain invisible characters any more.
  • In the DeviceLink module an index error has been fixed when selecting special profiles as Target Profile. (Ticket #180962).
  • In the DeviceLink module an index error has been fixed that occurred when using a profile that has not been saved to the systems profiles folder.
  • In the DeviceLink module the Gray / 100% Black exceptions have been fixed in case of CMYK-to-Multicolor with Target Profile selected as Color Generation mode. (Ticket #180781)
  • A warning message has been added to the DeviceLink module in case the Perceptual or Saturation rendering is selected in combination with the exception Adapt TVI to source profile. The warning should indicated that such Rendering options will not work in combination with the selected Exception.
  • In the DeviceLink module it has been fixed that when selecting the Preserve Color Properties Multicolor mode the black curve from the Curves diagram was gone.
  • In the Printer Profiling module it has been fixed that the sliders for Black Start and Black Width have not been disabled when Max Black is zero. (Ticket #180919)
  • The Black Point calculation setting Automatic has been fixed in the Printer Profiling module when importing a profile setting with a Multicolor black point. (Ticket #18071)
  • The Printer Profiling module will now refused to load reference data with more than 15 channels.
  • DEMO profiles will now be recognized by manufacturer tag instead of the file name. In previous version the key word “Demo” was used for the recognition which is not reliable.
  • It has been fixed that serialized Linearization DeviceLink profiles have not been saved to the chosen Custom profile folder under Preferences.
  • It has been fixed that Linearization DeviceLink profiles can be generated with CoPrA L, too. In previous versions this was not possible.
  • In the Linearization module it has been fixed that linearization curves shown under Curves from data have been displayed based on the ColorLogic default method but should be displayed based on ISO 20654. (Ticket #180698).
  • Several issues with selecting profiles in the Editing module have been fixed.
  • The speed of the Range slider in the Editing module has been increased.
  • Fixed some links to the Online Help and updated help content.
  • A floating point range validator to the dE Tolerance input has been added in the SaveInk module. This allows to manually enter values with decimal places.
  • In the Recalculate module the profile selection has been fixed. The profiles under Current profile and Recalculate with must both be valid, instead of before, when only one valid entry was enough. Note that this fix leads to a slower reaction of the user interface of the Recalculate module.
  • In the Profile Manager2D view in the Gamut tab of printer profiles with loaded Sample Data has been significantly improved. This will allow for a better recognition of in and out of gamut sample data values, and it allows for better recognition of matching data to a given L* slider position. (Ticket #181044)
    Note: In previous versions the dots that have been shown had a certain range around the selected L* slider position in the 2D view which made it hard to judge if a sample color had the exact L* value or not. Now bigger white balls in the 2D view indicate an exact match between the sample and the profile with the selected L* slider position. Light gray balls are a little bit smaller in diameter and indicate a match between the sample and the profile with 1 delta L* deviation to the selected slider position (e.g. values with L* of 49 or 51 in our screenshot). The smaller dark gray balls indicate sample data that are 2 delta L* away from the selected L* sider positions. Other values that are further away than 2 delta L* will not be shown.

CoPrA 5.0.1 - Profile Manager 2D

  • The new ColorAnt 5.1 with Measure Tool v2.1 has been included in the installer.

5.0 26 April 2018

CoPrA 5 is a major upgrade. The range of DeviceLink functionalities has been extended with a new Linearization tool, which is included in CoPrA 5 L and higher. New features in Printer and DeviceLink Profiling expanded the black generation and transformed it into the new Color Generation, offering convenient new options like an easy way to select or exclude individual channels for the separation or the visualization of gamut changes in real time. The new algorithm of the SaveInk module now allows even greater ink savings. Overall users will experience a faster startup of the application and users can get all this at competitive package prices.

DeviceLink Linearization

DeviceLink Linearization optimizes the tone values of primary gradation ramps for any printer and color combination. The goal of Linearization is for adequate differences from white to 100% of primary inks, smoothing of gradation curves and adjustment of primary colors to a defined, reproducible condition.

CoPrA includes the most advanced colorimetric technologies that are not readily available at the RIP level. ColorLogic’s Default calibration method and ISO 20654 (also known as Spot Color Tone Value, SCTV) are supported for Multicolor printing. CoPrA 5’s Linearization also features G7 calibration and the Protect Lights slider for Flexo printing and calibrating on difficult media and printers.

Calculation Modes can be used for CMYK and Multicolor printing with additional options for G7 for CMYK channels of Multicolor printer and ISO 20654 (SCTV) for spot colors.

How to create a Linearization DeviceLink

Print primary ramps on an uncalibrated printer without any color management. There are two ways to get the necessary measurement data for the creation of a Linearization DeviceLink profile:
Measure the test chart and optimize the measurement data using software, such as ColorLogic’s ColorAnt and open the measurement data in CoPrA; or measure data by using CoPrA’s Measure Tool.

Settings can be customized and the curves can be checked directly before creating a DeviceLink. This DeviceLink profile can be used in any workflow for any type of printing process. For example, when printing a profiling test chart on an uncalibrated printer.

ColorLogic ZePrA supports the use of Linearization DeviceLinks as gradation curves. By using this method, linearization can be applied in the workflow like corrections curves in a RIP. When applying corrections in the RIP other curves must be disabled to avoid double corrections.

Gray Balance Modifications

A new feature in the Printer and the DeviceLink module allows adjustment of the Gray Balance. Users can choose between a cooler and warmer gray balance. This is a nice feature when visual adjustments based on personal color preferences are desired even though perfect colorimetric profiles exist. The effects of changed slider settings are shown in the program in the adjacent graphic.

Note: The Gray Balance setting works independently from the Perceptual Rendering making it a perfect fine tuning tool for any chosen ColorLogic rendering. It will only be used for the perceptual rendering of a printer profile. However for DeviceLink profiling it can be used for any rendering including the four standard ICC rendering intents.

Excluding Channels when Separating

This new expert feature allows packaging professionals to define the channels (including Multicolor channels) of a printer or DeviceLink profile to be used when separating data. For example, if a brown chocolate artwork is intended to be printed in CMYK without using any Cyan in the separation, a CMYK printer profile can be created which only uses MYK. These types of profiles avoid unwanted Cyan dots in the separation and the converted artwork would appear visually close to a conversion with a complete CMYK profile. The new feature can be found in the Color Generation tab of the Printer and DeviceLink profiling modules. This function is particularly intelligent for Multicolor profiles as it searches for replacement colors in the Multicolor channels when excluding a channel (e.g. Cyan) which can compensate for the missing channel in the gray balance. The alternatively calculated Multicolor channels are displayed grayed out in the panel Black Point and TAC.

New Gamut Visualization for Printer Profiles

The Printer Profiling module includes a new feature to visualize the effects of the selected color separation and Black Point settings. The Gamut view available in the tab Color Generation visualizes changes of the gamut shape immediately when altering settings and provides a real time preview of the profile gamut to be expected. The user can immediately see how changes in the settings affect the gamut, for example, how a reduction of the Black Width slider or a very late Black Start reduces the ability of a profile to render dark colors. The Gamut Volume is calculated and displayed in Lab volume units allowing the user to easily find the settings that produce the largest gamut (highest number).

New Black Point Options

The Black Point and TAC of a profile are important settings as they define the maximum contrast and depth a profile is able to produce when separating data. We have changed the graphical display of the black point and added number fields for each channel with a colored icon in front of each number field. Editing will be faster, especially if non-standard color combinations are used in Multicolor printing with non-CMYK inks. The colored icons are a guide to the channels used to build the Black TAC. Depending on the selected Black Calculation setting the number fields are either disabled or enabled.Selecting Auto automatically uses all channels to calculate the black point and therefore individual editing of channels is disabled. The Auto mode will not use any Multicolor channels beside CMYK or in general the first four channels for the Black TAC.The mode Balance CMY allows editing of the black channel (or in general the fourth channel) and additional Multicolor channels. Entered Multicolor color values are fixed – like the Max.Black value – and CMY values will be calculated accordingly.

The mode Custom allows editing of all channels.

Note: For Multicolor profiles with more than four channels you can use the extra Multicolor channels for the black generation besides the first four channels (typically CMYK). However, the total area coverage (TAC) cannot exceed 400%. Values for the Multicolor channels can be entered manually when using the settings Balance CMY or Auto and these values will then be used to calculate the Black TAC. Usually it is not necessary to use those channels but sometimes a dark Multicolor channel adds desired contrast and definition. This can easily be checked by viewing the Lab values below the Custom fields. If the addition of a certain Multicolor channel decreases L* while a*b* values are not significantly altered, using this channel can be considered. However, the gray balance will use additional channels as well.

Improved SaveInk Module

The user interface of the SaveInk module has been streamlined and the save ink Methods have been simplified. Now there are only two methods – Easy and Advanced. The Easy method reduces the settings a user needs to define to a minimum but still achieves economical high quality profiles. Only three settings have to be adjusted in the Easy method: the Total Amount of Color, the Ink Saving slider and the exception Preserve 0% Black.

In the Advanced method all settings are enabled making this the preferred method for advanced users. It introduces a new dE-Tolerance slider which allows tremendous ink savings when set to a high tolerance. dE-Tolerance increases the maximum deltaE between the original profile and the SaveInk DeviceLink profile which results in greater ink savings. In contrast, the predefined Settings SaveNeutral, SaveStrong and Maximum use a low tolerance setting of 0.5 deltaE ensuring a very high color and visual accuracy of the profile. However if greater ink savings are desired it can only be done by reducing the visual accuracy, hence a higher dE-Tolerance setting is required. The new Extreme ink saving preset uses a high dE-tolerance.

Note: Users can save on ink even more by using a higher dE-tolerance setting. We recommend to test ink saving profiles with high tolerance settings closely before using them in production.

New Profile Search Feature

Everybody working with lots of ICC profiles on their system knows how hard it can get to find a specific ICC profile in a crowded drop down menu. In CoPrA 5, all profile drop down menus now function as a search field. Simply type in some letters of the desired profile and only those profiles containing these letters will be shown in the drop down menu. This is a feature power users will love. ESC deletes entries on the Mac and the previously selected profile reappears in the list. Under Windows it is sufficient to click elsewhere to delete entries.

Support for two Gamut Extending Colors per Color Section

The principle of ColorLogic’s Multicolor profiling works as follows:

  1. We support three main chromatic primary colors which should span a large enough gamut encompassing the gray balance. Typically this is CMY but it can be any other reasonable chromatic color combination.
  2. Black can be added as an optional fourth channel. If black is used it must be the fourth channel.
  3. Up to two gamut extending colors can be used in between each section of the main primary colors. This new functionality has been added to CoPrA 5 as CoPrA 4 supported only one gamut extending color.
  4. Following this approach, printer profiles with up to 10 channels could theoretically be created by CoPrA however, from a quality point of view it is not recommended to create profiles with more than 8 channels. Each additional channel increases the profile size exponentially, so that either a very low grid size or an exorbitantly large profile would have to be used.


The standard Multicolor case
If a standard Multicolor color space with CMYK parts is used, the additional inks Green, Orange and Violet extend the gamut in each section of the three primary colors. In between each section of the primary colors one gamut extending color is used making it a color space with 7 colors.

The advanced case
Some new inkjet printers use a Red and an Orange ink in addition to the standard CMYK inks. CoPrA is able to profile such a 6 color printer since Orange and Red are two gamut extending colors of the main primary color section Yellow and Magenta.

Note: Special test charts must be used when working with two gamut extending colors. Currently ColorAnt isn’t able to create such test charts. We have added new Multicolor test charts for those advanced cases which use two additional channels. The test charts are available via the Tools menu (Open Testcharts folder > Testcharts > Multicolor).

4.2.1 3 November 2017

New features

  • With quality improvements in calculating DeviceLink profiles, the color reproduction in highlight areas is improved. This is relevant for print processes which show large differences in tone value increases of highlight areas between the source and target profile, like flexo printing.
  • The calculation of Exceptions in DeviceLink profiling using Gray and 4CLR profiles as well as certain Black Generation modes (like MinK) have been improved.
  • In DeviceLink profiling, some warnings which occurred when using Exceptions have been optimized and improved. For example, using the exceptions Triplex and Duplex in combination with the black generation mode MinK is not recommended and now results in a warning message.

Bug fixes

  • Error corrections for the display of warnings: CoPrA displays warning or informational messages when selected settings are incompatible with measurement data or profile creation. However, an error occurred resulting in warning messages when creating printer profiles even though measurement data had not been loaded. This has been fixed. Additionally, an error has been corrected which displayed a message relevant only for CMYK profiles when updating RGB printer profiles.
  • In some printer profiling the calculation of the black point using the black calculation modes Balance CMY or Auto has been improved. In some cases, the black point had been created too colorful.
  • Links to the new ColorLogic website in the dialog Registration have been updated.
  • In DeviceLink profiling when changing source or target profiles the Preset selected by the user was changed as well. This has been resolved.
  • Image Conversion tool, not all Lab profiles were shown in the drop-down menu. This has been fixed.
  • The column width of the profile list in Profile Manager is now saved when manually resizing the width. This prevents a reset of the column width after certain changes, for example, after resetting a search.
  • Previously, the serial number had only been saved in the copyright tag of “regular” profiles. It is now saved in the copyright tag of Preview Profiles.
  • When creating DeviceLink profiles using more than four channels in the source color space, the creation of Preview Profiles is grayed out. Preview profiles for color spaces Gray, RGB or CMYK can be used in Photoshop.
  • Exceptions were not displayed correctly and switched to Auto when reading out settings from DeviceLink profiles. This has been fixed.

4.2 9 June 2017

New features

  • As of version 4.2 ColorAnt 4 and thus the new Measure Tool is included in CoPrA. Therefore, measurements of spot colors will now be executed using the Measure Tool rather than UPPCT. Detailed information about the Measure Tool can be found in the online help.
  • There are two new Multicolor Modes available for printer and DeviceLink profiling. In addition, the Multicolor Mode Strong has been revised significantly. Detailed information on the feature Multicolor Mode as well as the use of its modes can be found in the online help.
  • The feature Highlights, for simulating the first printed tone, has been expanded providing two new options for printer profiling and three new options for DeviceLink profiling. All options of the feature Highlights are explained in the online help.
  • The maximum value for the Highlights options has been increased from 10% to 20%. (Ticket #170078)
  • CoPrA SP (Serialized Profiles) creates encrypted profiles which are valid for the serial number of the licensed dongle or computer. Additionally, special licenses allow the generation of profiles which are valid for further serial numbers and thus can be used on other computers as well. Please contact us if you require such licenses.
  • The calculation of printer profiles using measurement data whose primaries are lighter than substrate white has been improved. Color values that are lighter than substrate white are no longer truncated, therefore better proofs can be created.
  • The user guide has been improved for multicolor and 4CLR profiles that don’t contain black. Information on Black Generation and Multicolor Mode will now be displayed during printer profiling. Information about the use of Exceptions will now be displayed during DeviceLink profiling.

Bug fixes

  • An exclusive SaveInk license which doesn’t require any further modules can now be issued.
  • The Predefined settings for the reduction of the total amount of color (TAC – Limit300 and TAC – Limit220) in the module Save Ink have been revised.
  • In the Profile Manager, the display of curves of multicolor profiles and profiles which are not composed of CMYK has been optimized. Curves are now displayed with the correct primary color name.
  • In the module DeviceLink the calculation of Exceptions in regards to Predefined settings has been improved.
  • The setting Black TAC is now correctly stored in the information tag of printer profiles, therefore it will be displayed correctly when imported into CoPrA again.
  • CoPrA can now be started by drag and drop of an ICC profile or by using the option Open with in the context menu of the operation system (Ticket #170170)

4.1.1 30 January 2017

New functionalities

  • The user interface now offers better feedback in the case of calculations. In CoPrA, various calculations are made for display in the user interface, e.g. for the preview of curves of the separation, the black point, or the exceptions for DeviceLinks. When calculations are made, the Next and Back buttons are deactivated and not released until the calculation has been completed. This ensures that no unwanted settings are applied to the profile calculation.
  • Profile reports for CMY printer profiles and DeviceLinks with CMY target profile can now be generated.
  • A filter for searching CMY profiles has been added to the Profile Manager.

  • In the DeviceLink module, display errors in the user interface have been fixed with the Exceptions in connection with the Automatic Mode.
  • In the printer profile and DeviceLink profiling, new Settings have been added for profiles without black separation. The screenshot shows the recommended settings (No Black Separation) for a CMYK profile that does not have black in the separation. Such separations are very useful for the pre-press in the packaging sector.

    For DeviceLink creation, the Print-to-Print – No Black Setting is for a CMYK-to-CMYK DeviceLink without black separation. Note that by default, the exceptions are set appropriately so that no black is generated.

Bug fixes

  • A serious error in the measurement data correction for RGB printer profiles has been corrected. (Ticket # 177647)
  • Errors in the slider for the setting of the Maximum Black in printer profiles have been fixed. The selected setting could be reset. (Ticket # 112546)
  • The error that new ICC profiles added to the system during the runtime of CoPrA have not been displayed has been fixed.
    Note: The profile lists are only updated if the application is re-addressed and brought to the foreground. Then wait until the profiles appear for up to 5 seconds. If the application is running all the time while profiles are being added, the profile lists are not updated to prevent unnecessary calls that would slow down the application.

4.1 17 January 2017

New Rendering options Saturation and Lightness

The Printer Profiling and DeviceLink modules have an extended Rendering option to change the overall Chroma, Lightness or Saturation of the profile with a slider. The Chroma option was available in former versions but the new Saturation option is even more favorable in situations where a more saturated color outcome is required. As with the Chroma option, the gray balance is not effected from the slider setting. It is recommended to use the Saturation option for large color spaces such as gamut extending Multicolor in order to let colors pop up more.
Note: The effect of each of the options is visualized in the gamut graph on the right side. As Saturation is calculated with chroma versus lightness, more saturation will darken colors slightly and thus will make them appear more vibrant. More Chroma will lead to high chroma colors being out-of-gamut and thus not will not be  able to be rendered with the given profile.

New Rendering Minimum White Compression

An additional Rendering option has been added to the DeviceLink  module. The new option Minimum White Compression is similar to the Minimum Compression. Both rendering options compress the white point so that no paper simulation appears. Additional differences are listed below.
Minimum Compression: is rather a perceptual rendering that additionally compresses the black point so maximum dynamic range is utilized without loss of detail in the shadow area (vs Minimum White Compression).
Minimum White Compression: Compresses the white point but not the black point, so a close match between source and target color spaces can be achieved. This can be beneficial for cross media color appearance, color matching or printing on slightly different media. It can be regarded as close to absolute colorimetric rendering.

Improvements to the Profile Report

  • The Profile PDF Report and the Color Comparison PDF Report features have been improved in the layout with some flaws corrected. The Color Comparison Report for Correction DeviceLinks new sections show the TVI curves before and after correction have been added.
  • In addition, if Brightener correction and Measurement data correction have been applied when creating the updated profile this modified data is compared to the original and updated profiles in the Color Comparison Report. In the past, only the original measurement data was used which didn’t show those corrections which have a big impact on the data, leading to less meaningful report results. (Ticket #781460)
  • It is now possible to upload a company Logo in the PDF Reports generated from CoPrA. As a default the CoPrA icon is used in the report.
  • Adding a Sub Title to the report is now an option. Those new Report Customization features are available in the Preferences.

Other new features and improvements

  • The Highlights option First Printed Tone in the Printer Profiling module has been qualitatively improved and a new feature added. The simulation of the first printed tone in proofing now has better calculation. In addition, in case the loaded measurement data has enough fulcrums in the highlights, CoPrA will provide information about where the first printed tone starts in the measurement data. This information is helpful as a guide to which value will be used in the number field on the right side.
    Note: The information Based on data will only be provided if the First Printed Tone option has been selected in the drop down menu and the data allows detection of a first printed tone different to the default that excepts no specific highlights behavior.
  • The calculation of Preview Profiles for Multicolor printer profiles and DeviceLinks is supported with a Demo license now. This is helpful for new clients who wish to test the application and receive a demo license from us.
  • With the installer of CoPrA 4.1 comes the new version of UPPCT v2.3.5 that supports the X-Rite eXact instrument.
  • The Simplified Chinese translation has been optimized and missing strings translated. (Ticket #270904)
  • In the new 4.1 version uses may define a custom folder for saving all their ICC profiles. As a default the profiles will be saved in the systems ICC profiles folder but if a client requires to have his profiles somewhere else, for example a shared drive on the network, he may define such a folder in the Preferences. Subfolders for the various profile classes and color spaces will be automatically created containing the generated profiles.
    Note: Profiles that are stored in a custom folder may not be available for other applications if they are not stored in the required system directory. As a tip for Mac users: You can define a subfolder in the ColorSync profiles folder so that all ColorLogic profiles created with CoPrA are stored in one place and you can still enjoy using those profiles in all ICC aware applications at the same time.
  • The Extreme mode in the SaveInk module allows to Preserve Secondaries in case the TAC is below 200%. As there seems to be a tendency in Newspaper printing as well as in high speed inkjet printing to use less than 200% of TAC, not selecting the Preserve Secondaries option may lead to an unwanted reduction of secondary colors (that require 200% of ink) and thus washed out colors. While the TAC in the dark colors and the black point will be reduced below 200% the Preserve Secondaries option makes sure that full reds, greens and blues are maintained.
    Note: The Extreme mode may reduce secondaries if possible to save on inks. If you wish to exactly maintain 200% of colors for red, greens and blues you should select the Maximum  mode instead.
  • Information and explanation texts have been added or exchanged at several locations in Profile Manager to increase the users understanding of what he sees in the dialogs. For example does the Curves view of a printer profile allow to see the traditional TVI curves based on Murray Davis and the TVI curves based on colorimetric linearity which is a more modern standard (close to ISO 20654).

    Another example is the Colorants tab that shows the names and Lab values of the colorants used in Multicolor profiles. As the ICC states in its specification, that Lab values must be relative colorimetric so we made this explicit in the table header. This should eliminate confusion for users if their measured absolute colorimetric values of the primaries differ from those indicated in the table, as this is by design.

    As a last example, the Gamut tab is mentioned. To avoid confusion as to why the tab is empty, it is in the case of a selected DeviceLink profile, an information message will display below the graph stating that for DeviceLinks no gamut can be displayed.

Bug fixes

  • The calculation of the Gray Exception in the DeviceLink  module has been improved. For some profile combinations grays are now rendered darker and thus more faithful to a four colored gray that one would get not using the gray exception. (Ticket #138870)
  • In the Printer Profiling module the Viewing Condition  option XYZ has been fixed. It was not possible to edit or change the values before. (Ticket #463599)
  • The encoding of the description tag in ICC version 2 profiles has been changed to 7bit ASCII instead of MacRoman before.
  • Scanner profiles have led to a missing ICC tag message when creating reports and could not been used as input profiles in the Editing module. Those issues have both been fixed. (Ticket #494379)
  • Several issues that have made the reaction time of the GUI quite slow in some circumstances in the Printer Profiling and DeviceLink modules have been improved leading to faster performance when changing settings and sliders. In addition some scaling issues in the table showing the profiles in the Recalculate module have been fixed.

4.0.2 20 June 2016

  • Fixed minor layout issues in the PDF Profile Report.

4.0 20 April 2016

Integration of the Reprofiling Technology in CoPrA 4

Reprofiling is a term we have introduced in our product DocBees-Repofiler to describe an innovative profiling approach that does not require to print a large test chart and to define each and every profile settings from scratch. Instead the reprofiling approach uses only little information (measurements from a small color wedge) and an existing profile to update that given profile. The goal is the creation of an updated profile for changed printing conditions in an easy and fast way.

Based on the updated profile it is possible to build a Correction DeviceLink profile with special settings which allows to take the deviations into account to be able to re-print colors as close as possible the same way as before the deviations. This is a very helpful feature in order to minimize color appearance changes in the print run during production despite print changes. To a certain extend even paper color and bigger ink changes can be compensated for.

The reprofiling technology is now include as an additional printer profile module called Update Profile in CoPrA 4. There are a nice improvements associated with this move:

  • Updating of Profiles is possible for RGB, CMYK and new for Multicolor color spaces, too.
    Note: Multicolor profile updating requires the Multicolor license.
  • The new Update Profile module is an integral part of any CoPrA 4 package. In other words CoPrA clients will have both options to build a profile from scratch using the New Printer Profile option and to update a given profile in case of print variations.
  • An existing CoPrA 3 client will get the Update Profile functionality as additional module after upgrading to CoPrA 4.
  • The product line DocBees-Reprofiler will end with the release of CoPrA 4. But existing DocBees-Reprofiler customers can upgrade to CoPrA 4 Basic package to get not only the newest and improved reprofiling technology but they will get access to CoPrA’s high quality printer profiling module, too.
    Note: The CoPrA 4 Basic package allows to create profiles based on presets. Custom settings, like separation, black point options or rendering settings can not be modified with this version.
  • In the past some DocBees-Reprofiler clients requested the need for advanced profiling settings, e.g. to specify the separation settings and rendering options. This will be possible with the CoPrA 4 M package and higher as all the CoPrA printer profiling settings including custom settings are available for updating of profiles, too.
  • With the DeviceLink possibilities within CoPrA 4 customers can do even more than with the previous version of DocBees-Reprofiler XL. They can now not only build a DeviceLink that is suited to compensate for the print deviations but they can build DeviceLinks from different source color spaces to the updated profile or from the updated profile to different target color spaces. This makes the DeviceLink profiling much more versatile compared to what DocBees-Reprofiler XL has created.
  • CoPrA 4 has integrated new features helping the user to better understand if a profile needs to be reprofiled or not by visualizing the match of the measurement data compared to the reference profile selected.
  • One of the many great feature in CoPrA is the detailed Profile Report as PDF file that can be generated. For updated profiles an additional Profile Comparison Report option is available. This new Report has been totally overhauled with more information helpful for the client to learn about the improvements when applying the updated profile.

New DeviceLink Profiling module in CoPrA 4: Recalculate

The Update Profile functionality will optimize and maintain the quality of your daily print production with updated printer profiles. But you might have a bunch of DeviceLinks using your original profile already that would need to be rebuild with the updated profile. This could be a time consuming work. The new module Recalculate that is located in the DeviceLink section will make this fast and easy. You simply tell the software to rebuild all existing DeviceLinks using a certain profile with your updated profile. CoPrA will then lists all those DeviceLinks and you can decide which of them shall be rebuild and if you want to keep the original or overwrite it or if you want to rename something. After that you simply click to build the profiles and all of them will be calculated automatically using the same settings of the original DeviceLinks.

Other improvements

  • CoPrA 4 has an improved GamutMapping. Especially for small, mal formed and “strange” color spaces which are more common in industrial applications like textil, ceramics and high speed inkjet, the new GamutMapping will lead to improved results. Higher saturated colors and smoother blends providing colors results closer to the original colors you wish to produce.
  • The quality of the multicolor profiles has been tremendously improved both in terms of accuracy for proofing purposes as in terms of increasing the gamut and better separations. The Multicolor Mode smooth has been set as default method instead of strong.
  • The profile sizes of printer profiles has been changed so that profiles will be larger in size due to using optimized grid points. This and other changes in the algorithms lead to an increased accuracy of profiles.
    Note: Pay attention with using multicolor profiles with the very large profile size. Some CMMs and applications on the market may not be able to handle them but the Image conversion feature build into CoPrA or our color server ZePrA can handle them, which demonstrates the advanced capabilities using the ColorLogic CrossXColor CMM.
  • The smoothness of CMYK-to-CMYK DeviceLinks has been noticeably improved.
  • CoPrA 4 is the first ColorLogic universal binary application on the Mac. E.g. you can decide to run the application either as 32-Bit or 64-Bit with 64-Bit being the default.
  • Multithreading support has been added to CoPrA 4. Several profiles can now be calculated simultaneously making the profile creation process for power users much faster than before.
  • For Multicolor-to-Multicolor DeviceLinks with the same amount of channels a new Multicolor Mode to Preserve the color properties of the source color space has been added. This mode allows for the Exceptions to be applied on all multicolor channels and not only the CMYK parts.
    Note: For example the primaries exceptions would maintain all primaries and the secondaries exceptions would maintain combinations of any of two primaries and not only those with CMY combinations.
  • There are two new filters in Profile Manager to search for Updated Profiles and Correction DeviceLinks on your system.
  • New context menu features in Profile Manager allow to choose a given printer profile to be either the source or the target profile for DeviceLink creation. For updated profiles an additional option is available that sets the required profiles and settings for building Correction DeviceLinks automatically.
    Note: After you have selected one of the new options you may switch to the DeviceLink module to check settings and to build the DeviceLink.
  • Simplified profiling presets for Digital Printers. Now clients do not need to select between two presents for profiling digital printer any more as it was in CoPrA 3. The Digital Printer preset will automatically check for the best black point and takes into account non subtractive color behaviors automatically based on the measurement data.
  • New option when creating DeviceLinks to Embed Profiles. This option embeds the source and target profile in the resulting DeviceLink. This would only be helpful in case the profile is shared on an other computer where those source and target profiles are not existing. In addition the main reason is one RIP used in the market seems to only accept DeviceLinks if source and target profiles are embedded.
    Note: The file size will be tremendously bigger as printer profiles are mostly larger in size than DeviceLinks. We recommend to only use this option if one of the two reasons mentioned above apply. ZePrA and other ColorLogic applications for example do not recognize such embedded profiles.
  • Support of 2CLR, 3CLR, 4CLR profiles in Image Conversion.
  • Image Conversion supports Lab profiles now.
  • The embedded profile of a loaded images in the Image Conversion feature has been shown in previous versions of CoPrA. Now the embedded profile will be selected as source profile automatically.
  • Changed software behavior regarding showing and using of demo and serialized profiles in the drop down menus for profiles. Demo profiles will only be shown in a demo version of CoPrA and not in NFR or payed software. Serialized profiles – encrypted profiles working with a specific serial number – will only be shown in case the serial numbers between profiles and the recent CoPrA version match.

Bug fixes

  • Manual typing of a TAC value in the number field under Blackpoint and TAC will not change the Black TAC directly in an unfavorable way any more. Type in the value and press the tabulator or enter key to provide the value to the software.
  • Importing settings from SaveInk profiles work better now.
  • Creating of CMYK profiles from multicolor data works correctly again if the GUI was set to background before creating the profile.
  • A late Black Start is improved noticeable in DeviceLinks when creating a new separation. Now the back is not used in lighter values any more.
  • Fixed several quality issues regarding the use of exceptions for DeviceLink profile creation.
  • Several bug fixes to improve stability and usability of the software.

New features

Black Point and TAC

Under Black Point and TAC you can define the overall Total Area Coverage (TAC) and the TAC for the black point (Black TAC). The Black TAC  is the darkest color in the profile which in most cases is identical to the overall TAC.

Modern printing systems allow printing of a dark black point by using a low amount of ink. Sometimes only pure black is required to print the darkest black which means 100% black is already sufficient enough. Obviously such a low TAC will not work for other color areas – an example would be a pure red with this TAC.

Therefore we separated the Black TAC from the general TAC  in the Printer and DeviceLink Profiling. This allows the best black point calculation without any unwanted influence on the overall color space.

In addition to the calculated Lab value, CoPrA 3.3 and higher  also shows the percentage value of the generated Black TAC (red frame in the screenshots below). The sliders don’t adjust the calculated values as in previous versions of CoPrA – which enables you to maintain the predefined values.

Note: Separate TAC and black point settings may be required in certain new generation printing equipment including large format and digital printing systems to ensure proper gray balance with high contrast, while maintaing highly saturated colors.

The options for the  Black Calculation  are explained in this article.

Black Point and TAC example

The following example of a digital printer shows the advantage of the two different TAC settings. By utilizing the optionsAutomatic or Neutral CMY for Black Calculation and would start from a Black TAC of 400%, CoPrA will calculate the most likely best black point TAC. The calculated black TAC will be displayed like in the screen shot below. In this example aBlack TAC and the general TAC of 275% will be calculated. The black point is very neutral (a* and b* are both set to 0) but the L* is only set to 16.6 which might be a bit too light.

Reducing the Black TAC to the for digital printing systems typical use of pure black as the darkest printing color, the Black TAC will be set to 100% and the black point has a L* value of 11.9 – so much darker. Therefore a much better contrast can be reached with this setting than with a Black TAC of 275%. Setting in a general TAC to 300%, also enable printing of highly saturated colors. Without these two separate settings it is not possible to  won’t be able to achieve quality results.

New Profile Report features and profile quality improvements

  • The  PDF Profile reporting  for multicolor printer and DeviceLink profiles have been improved. CoPrA 3.3 adds more accurate visual color previews of ColorLogics’ test images. By applying the methods below, Acrobat will display a more visually accurate report for multicolor or devicelink profiles.  The  PDF Report test images are converted with the following methods: Lab to perceptual and also relative color metric plus black point compensation, images are converted to DeviceN.
  • The Spider Web diagram in the  PDF Profile Report has been extended to better show the color of the primary and secondary CMYK axes of printer profiles. Multicolor profiles are displayed with the extending colors similar to ColorAnt 3. Colored points and colored lines drawn to the next neighboring primaries.
  • Gamut Mapping quality has been improved for lighter color regions specifically for small color gamuts.
  • The generation of Multicolor separations of in-gamut process colors have been optimized. In-gamut process colors are located within the gamut of the three main colors (the main colors are often CMY). Adding in-gamut colors is typically not recommended because they are not extending the gamut of a profile. In certain instances these colors are required in production. ColorLogic recommends the  Multicolor Mode Strong. The separations of in-gamut colors with this setting generates has been improved over previous versions.
    Note: In-gamut colors are not used with the Multicolor Mode Smooth.
  • Black point and gray balance rendering with the Multicolor Mode – Sparse Inks setting has been improved by using CMYK as the Strong and Smooth modes. The results are noticeable most noticeable in the shadow details.

Bug fixes

  • Crashes of CoPrA in combinations of imported profile settings and clicking the  Home button have been fixed.
  • Several issues importing profile settings have been fixed including issues such as profile settings could not be imported or crashes of the application or wrong display of settings.
  • Saving custom profile settings with a custom name using the Save as works without changing settings.
  • The error that the CoPrA3  folder under Documents was not created on an initial installation has been fixed. This fixes a subsequent error message appearing when the  Preferences dialog opens.
  • A general error message appearing in some cases a PDF Profile Report should open has been fixed.
  • We have changed the limit for TAC reduction that CoPrA could use with appropriate data to 275% instead of 300% when using the Black Calculation  options Auto or Balance CMY. This improves the black point calculation for several data where the previous limit prevented a better result.
  • Several improvements in the generation of Printer and DeviceLink profiles have been carried out. For example works the Max RGB exception in combination with the Multicolor Mode Smooth now as expected. When using Max RGB one channel will be set to 100% to increase saturation.
  • The creation of CMYK profiles without any black (K=0%) works again using the new version. This will create a CMY separation with no black.
  • Issues with the Black Generation Mode MaxK when using a late Black Start  haven been fixed.
  • The  Image Conversion feature retains the file format of the image to be converted if possible and does not change it to JPEG as default any more. In addition the file format will be correctly used when changing to a different format now.
  • The index error while using gray profiles in the  Image Conversion  feature has been fixed.
  • Numbers fields are now checked for incorrect entries like characters or numbers exceeding the range of logical input values.
  • Profile Manager displays the curves of DeviceLink profiles created by ZePrA’s  SmartLink feature.
  • The parameter error message when creating a CMYK profile from a 4CLR data set has been fixed.
    Note: In general from nearly any Multicolor data set a CMYK profile can be build using the checkbox Calculate CMYK Profile. This will work with data sets with more than  two channels (except RGB). When a data set does not have a black channel it will be regarded as if it would have one to build a CMYK profile.
  • Custom channel names for Multicolor defined in ColorAnt 3 Custom Chart tool are used correctly now when building the profile with CoPrA 3.3 instead of creating other channel names.
    Note: In case undefined channel names in multicolor data sets from 3rd party tools are provided to CoPrA, it tries to figure out and use logical channel names from the hue of each channel automatically.
  • Incorrect display of IT8 formatted measurement data files provided from third party instruments (e.g. multiline quoted values from Barbieri Gateway) has been fixed. Some small syntax errors certain third party files that prevented CoPrA from opening them have been fixed. CoPrA is more tolerant with such files and will use them.
  • A few issues displaying 4CLR test charts and the Multicolor test charts delivered with CoPrA correctly when measuring them with  UPPCT have been fixed.
  • The error that a profile selected in the Batch Overview feature was not shown in Profile Manager due to blocking filter settings has been fixed. Now filter settings from previous selections in Profile Manager will be deleted.
  • An intermittent error for loaded measurement data in the  Printer Profiling dialog when using the Fit to width checkbox has been solved.
  • The error that the CoPrA splash screen when starting does not disappear any more if  UPPCT was started at the same time from within CoPrA has been fixed.
  • Some issues with separation curves not updating correctly in the Black Generation tab have been fixed. In addition the displaying error of the vanished file name of measurement data in the  Printer Profiling  dialog when resizing the dialog has been fixed.
  • The use of the X button for deleting existing measurement data in the  Printer Profiling dialog works again without producing a format error message.
  • Minor errors in the Registration  dialog have been fixed.
  • The Profile Report feature uses the channel names of Multicolor profiles correctly in the  Dot Gain section now.
  • The TAC  for Multicolor DeviceLink profiles is not exceeding the user defined value any more in combination with the Highlights  option  First Printed Tone  from the Exceptions  tab.

Satiskin Textiles has to test less & saves ink with ColorLogic products

Antero Pedras

Satinskin Textiles is a digital textile printing company located in Portugal, exporting 90% of their production. They use CoPrA and ColorAnt applications in their workflow.

Antero Pedras of Satinskin Textiles is responsible for the in-house software development that goes from the production system over the ERP to their RIP software. He explains his experience with ColorLogic: "We work with several machines from various manufacturers and it seems that CoPrA and ColorAnt fit well into our current workflow, providing outstanding results. Prior to using ColorLogic, we had an issue with the color blue appearing more purple in profiles and the gray balance not being very accurate. The gray balance feature in CoPrA is great, giving us complete control to where we want our grays to go, color wise. In addition, our previous solution did not provide multichannel devicelinks, and having this ability to convert with CoPrA multicolor profiles provides better efficiency all around."

Overall, Antero Pedras is very happy with how simple the applications are to use, while still providing the best possible results. "ColorLogic solutions really provide a high return on investment, because in the end the user needs less testing and saves ink", says Antero Pedras.

From prototyping to final prints – Impresiones y Prototipos, s.l. trust ColorLogic for all their color management needs

Alberto Gómez, CEO

To satisfy the ever changing requirements of the printing industry you need flexible and yet still specialized solutions to address those needs in the best possible way. We spoke with Mr. Alberto Gómez, CEO of the printing company Impresiones y Prototipos, s.l. in Barcelona, Spain, who is mainly responsible for the strategic development of the whole company. He focuses on quality improvements, solutions to fulfill specific customer requirements while looking for new opportunities to expand the activities of his company.

Mr. Gómez, could you please describe your company with a few words…

Our company Impresiones y Prototipos, s.l., is a printing company located in Barcelona (Spain) with over 30 years experience in the printing industry. Three years ago we created a new division “Zeta Prototypes” which specializes in prototype packaging. Our main clients here are located in the high-end sector of perfumery. Due to the high quality of our prototypes and the great success we have achieved here in Spain, we just started our international expansion prototypes packaging division. Our goal for 2015 is to establish this international business.

Please tell us a bit how you  became aware of the ColorLogic products and which ones you are using…

We use CoPrA and ColorAnt to optimize our measurement data and create ICC and DeviceLink profiles. Afterwards we process files by using the color server ZePrA. After we  validated how this powerful color management engine helped us to improve our print data, we also have included the ZePrA module for Spot Color conversion, which is very important for us. We also just started using the Reprofiler, which we think is a very interesting solution for handling slight changes in the print process without the need to regularly create completely new profiles.

A while ago we had some color issues in our production. I was looking for better ways to achieve color fidelity and shorter make-ready times. Someone recommended Daniel López from ID-Soft to us. He helped us to evaluate the right solutions and then integrated the ColorLogic products for us. Daniel is an excellent color consultant. He is very knowledgable and probably one of the best technicians for colorimetry in Spain. He also introduced us to the ColorLogic products.

This sounds very enthusiastic. So which are the biggest advantages you see in working with ColorLogic solutions…

We tried many other color management solutions, but we were never able to achieve our goal with them.  Our goals are to create high-quality prototypes and ensure the same colors in the final print. It is also important to know that theses prototypes serve as samples for all further printing processes. With the ColorLogic solutions, we saw from the beginning that we could achieve this goal, because they are very powerful and versatile. Before we changed our production, we had to perform many tests to get a color fidelity prototype. Since we began using  ColorLogic technology these tests have been drastically reduced  while also giving us a substantial increase in production  without comprising the print quality. Additionally, due to ColorLogic’s products we can manage color in all material we work with: Polyester, Folding, Leather, PVC, PET, etc, knowing that we will always obtain the best result of reproduction.

Anything else, you like to highlight…

Each prototype we do is a unique work. Our customers rely on our quality and with our optimized production we have have been able to achieve for our prototyping a 95% realism in comparison to the final industrial production. Today we are the 1st company in Spain which is certified by the best companies. So, now that we have such an extensive experience in conducting professional prototypes, we begin our international expansion by offering prototyping to other countries.

This is a great step and we wish you good luck for this exciting expansion. One last question: What do you think about the price – value ratio of ColorLogic products?

It is not a cheap solution, but I think it is complex to define what is cheap or expensive… Of course, it depends heavily on the objectives that are achieved. In our case, although it looked like a major investment in the beginning, we believe this was worth the money spent. Meanwhile we improved production tremendously and added value based on the professional knowledge of Daniel López. And if we ever see new requirements we can always discuss those with him. So for sure, I would do the investment again.

Thank you very much, Mr. Gómez and good luck for all your exciting activities.

The new ZePrA 4 is “running” at the German alprinta GmbH

Jan Lukat, Prepress Manager

The latest version 4 of the high-performance color server ZePrA, developed by the German ColorLogic GmbH, has successfully passed its test period at alprinta GmbH.  For some time now, alprinta GmbH has used Colorlogic‘s products ZePrA, CoPrA, Reprofiler and ColorAnt for their daily color management tasks. Ever changing print conditions in digital and screen printing, along with the special needs regarding exact reproduction of spot colors, calls for high-end color management solutions as one of the key success factors for alprinta.

Alprinta‘s prepress manager Jan Lukat tested ZePrA 4 before its official release:

“I really like to test new products for our production. The printing industry is changing constantly and only by adopting your production process to these changing requirements, allows you to maintain and optimize it. I also appreciate the quick response of the development teams responsible for the products we use here at alprinta. In addition, it enables me to share  feedback and ideas regarding future development which may benefit all users.“

Lukat explains how the ZePrA color server is used at alprintas‘ production in combination with ColorLogics‘ CoPrA (ICC profiling): “Instead of repeating the general advantages of the ColorLogic products, I like to focus on new features in ZePrA 4 / CoPrA 3 which are so beneficial for our daily print business:”


Until now the standard process was to generate printer and DeviceLink profile with CoPrA and re-profile with Reprofiler, each combination of printer, material and printing speed. The resulting DeviceLink profiles, were used for color conversion in ZePrA. Dealing with ten different print materials, three printers with three different speed settings ends easily in handling of 180 profiles (90 ICC and 90 DeviceLink profiles). The printing results are outstanding, but whenever something changes: material, settings, etc. all profiles need to be redone to maintain the quality. With the new SmartLink module in ZePrA 4 it is now possible to share DeviceLink settings between CoPrA 3 and ZePrA 4 and cuts with one “click“ the amount of profiles in half. ZePrA calculates automatically the required DeviceLink profile based on the related output profile. There are also pre-defined settings available for SmartLink.

Gamut warning

This new feature is one of my favorites. Especially in large format printing with its different kind of materials and reproduction capabilities. All clients require perfect reproduction of their CI colors and spot colors. Therefore, it is essential to know if those colors may be reproduced with the chosen settings. With ZePrA it is possible to define a variable for DeltaE2000 (deltaE2000 fits nicely to human color prediction) to track if the color shift is good enough to continue with the print or not. This goes very well together with the new rendering intent Minimal Compression in CoPrA 3 which allows the best possible nearly absolute colorimetric reproduction. Who can ask for more!

Transparency reduction

With the new Flattening options it is possible to reduce transparencies quickly either on single jobs or whole plates and ensure the best possible reproduction without running into problems with transparencies or spot colors. Daily print production has proven that reduction of transparency is required. Even working in a PDF-X/4-Workflow can lead to those unpredictable problem which can be solved now.

Report function

All  job settings may be stored manually in ZePrA by using the report function – in ZePrA 4 it is now possible to do this automatically and store it in a folder. I believe that this is essential to guarantee future reproduction and archive customer data. Thank you, ColorLogic, for realizing this customer request!


Finally, the most important point for all decision makers: Even if all topics mentioned are already more than helpful in daily reproduction work, you will enjoy the SaveInk module in ZePrA 4 and CoPrA 3 on top of it. I was able to realize approximately 20% ink reduction in 1000 print job without any loss of quality. Especially in large format printing where ink costs define the print costs – this could make the difference.  This function pays off from your first print job on. Additionally, with the different SaveInk levels you are able to define quality and rentability.

About alprinta

The German alprinta GmbH located in Leverkusen has been successfully working in print and display production for more than 30 years. Their core competence lies in digital and screen printing as well as advertisement, displays and UV offset. Alprinta is one of the market leaders in the area of display advertisement. This success is based on over 50 motivated and highly experienced employees.

Measurement data preparation using ColorAnt at Appel Grafik

Ulf Wittenberg

“My sincerest thanks to ColorLogic for the new ColorAnt tool for measurement data preparation!” writes Ulf Wittenberg from Appel Grafik, who as a long-standing customer was involved in the beta testing of CoPrA 2 and ColorAnt in 2011. The report from Ulf Wittenberg at Appel Grafik on his experiences shows why…

Appel Grafik is a media service company based in Germany with sites in Berlin, Düsseldorf, Frankfurt, Hamburg, Munich and Stuttgart. The Appel Grafik sites have been using the DeviceLink profiles created by ColorLogic CoPrA for many years for high quality and standardized color conversion of PDF files and pixel images. Ulf Wittenberg, Color Manager at Appel Color department creates, tests and optimizes the DeviceLink and ICC profiles centrally for the Appel Group, enabling him to ensure consistent color quality throughout the company.

Ulf Wittenberg continues:
“At last with ColorAnt there is software for MacOS and Windows for applying corrections such as measurements smoothing or compensation of optical brighteners to the measurement data – and as a CoPrA 2 purchaser it is free of charge, too. ColorLogic has also integrated even more extremely useful functions with the help of its outstanding and highly customer-oriented team.

The measurement data correction and smoothing are extremely helpful in our everyday work, particularly in calculating output profiles for color laser printers that despite careful calibration often still have notable irregularities. In addition, papers with a significant amount of optical brighteners are often used in production that in turn generate problems of a different kind when their effects cannot be corrected. Using ColorAnt, the necessary corrections can be included in the measurement data and their effect checked in advance of the profile calculation. The corrected data are then reflected in the CoPrA profile as well.

The other tools in ColorAnt are also fantastic – some outstanding examples include:

  • Extraction of the color fields for Ugra/Fogra media wedge V3 – saves time-consuming additional work on manual spreadsheet edits in many cases when reference values have to be created for the media wedge evaluation for in-house proof conditions.
  • Visual displays of the measurement data – nicely implemented functions for thoroughly examining the submitted corrections for their appropriateness.

The whole package is rounded off by a comparative function with statistical evaluation and a PDF report. This provides a really comprehensive overview of the quality of the printers measured.

This combination of advanced color management tools was previously only possible using several different programs from various manufacturers – to have all this in just one program that is really easy to use makes us really happy!

In summary: ColorAnt easily exceeds our expectations and feature requests and has become an indispensable tool in our workflow.”

Red remains red and green remains green – SKN counts on ColorLogic‘s color server ZePrA

Tielko de Groot, Prepress Manager

The German SKN printing and publishing group has a long tradition which dates back to the last century. SKN currently employs approximately 450 employees.  The publishing area covers over 30 different telephone books, the monthly magazine “Ostfriesland Magazine” and also publishes books. With its daily newspapers “Ostfriesischer Kurier”, the “Norderneyer Badezeitung” and two additional weekly newspapers, the SKN is also well known in the German newspaper publishing.

Beside these activities, the SKN is one of the largest industrial printers for high volume printing in Germany. According to their motto, “SKN – Competence in printing and publishing“, the SKN delivers high quality on a good price-quality-level. Besides highly educated and motivated employees, it‘s essential for the development of such multifaceted company to use the right technology and to have a close contact to all clients. Therefore, it is very important for the SKN to take special care about job printing and close customer relation. In other words, to present itself as a competent and reliable partner with whom it is easy to work with.

Tielko de Groot is the Manager of Prepress at SKN and, in addition, responsible for training and internal complaints department. Several years ago, a print consultant introduced him to the products from the color experts ColorLogic. The possibility to handle all print related data in the correct color space convinced Tielko de Groot to ColorLogic was the obvious solution. Due to the importance of using InkSave in SKNs production, they decided to work with ColorLogic ZePrA and the ColorLogic DeviceLink profiles.

ZePrA controls the colors

Tielko reports: “Working with a reliable and fast color server, which can be configured in an easy and understandable way, is really great. ZePrA is responsible for most of our color conversions and ink saving calculation of print data for sheet-fed and web-fed offset printing. For example, to adjust color data to the different Fogra characteristics of several paper types is an easy and fast task. Furthermore, by using an automation software like Enfocus Switch, the automation process in production can be additionally increased”.

Regarding the DeviceLink profiles, Tielko says: “At first, I like to highlight the fact that the DeviceLinkSet profiles have proven its usability during several print tests with Fogra certified color consultants. That main advantage is that it enables proprietary systems to deliver the same results as ZePrA. Therefore, we are using those profiles especially in newspaper production with Kodak Prinergy to apply SaveInk directly before printing. Before deciding on this production method, we tested a competitive product, which produced several errors. The generated print data were useless for production. However, the ColorLogic products are very reliable and need more or less no support at all. The few questions which have been raised so far, have always been answered fast and sufficient by ColorLogic and Karsten Schwarze from our dealer Impressed.”

Another advantage regarding the correct output in production rests, based on Tielko de Groot statement, in the fact “that the color server can be set to only adopt the images inside the PDF (or image files itself) and does not rip the complete PDF files or creates a complete new one or does any additional modification. This leads to a higher performance, too.  And it keeps me independent from any PDF library settings …” He went on to say, “I believe investing into a color server only happens once – and therefore you should better proof that it lasts. With ZePrA return on investment is ensured. By the way – we are also using ZePrA in our subsidiary OPD.”

  1. Drag and drop the measurement data "Indigo5600 7C.txt".

Customize the multicolor printer profile

  1. Click "Customize".

Customize general options in the multicolor printer profile

  1. Click "General".
  2. In the Perceptual Rendering drop down list choose "Standard Compression".
  3. Enter the chroma "0".
  4. Click "Black Generation".

Customize the black generation in the multicolor printer profile

  1. In the Multicolor Mode drop down list choose "Smooth".
  2. In the Mode drop down list choose "MaxK".
  3. Enter the Black Start "0".

  2. Click "Next".

Save the multicolor printer profile

  1. Change the name to "Indigo5600_CMYKOGV_TAC300.icc".
  2. Enable the checkbox "Create Profile Report (PDF)".
  3. Click "Save".

Analyze the saved multicolor printer profile

The multicolor printer profile "Indigo5600_CMYKOGV_TAC300.icc" is successful created in the ColorLogic shared folder (Users/Shared/ColorLogic).

Analyze the profile report

The profile report from the created printer profile opens automatic in your default PDF reader. The report contains colorants info, profile statistic tests, gamut curves, gamut volume table, gray balance curves, sample images, RGB conversion tests, hue samples, linearity curves and dot gain curves. The report is saved in the CoPrA "Reports" folder (User/Documents/CoPrA/Reports).

How to upload large files to support?


When sending problems to support or asking questions about a specific functionality, it is always helpful if you supply as much information as possible:

  • Profiles or Process Plans when working with pdfToolbox or pdfaPilot
  • Example documents 'before' and 'after' to explain the problem or question
  • Screenshots explaining the specific problem

When such files are over 2MB it is more reliable and quicker to send them to us through our Dropbox. This article describes how to do so.


  1. First of all, please give your documents a unique name. If you already have a case ID (a 5-digit number), please include this case ID in the name of the file(s) you are going to send to us.
  2. Click this link to browse to our Dropbox upload page
  3. Click 'Choose files from your computer' and navigate to the files
  4. If you are not logged into Dropbox, fill out your First and Last name and email address
  5. Click 'Upload'

You will receive an email confirming your files were uploaded succesfully.

Are the ColorLogic products competition to X and Y?

Likely :-) ColorLogic offers a very comprehensive color workflow solution and more than likely it overlaps in functionality with some of the other tools in the market that you know. The important thing to remember is that we believe that the ColorLogic solutions have a number of key differentiators and advantages:

  • The quality of the tools is superb.
  • These are probably the best color tools out there today. 
  • They offer a very nice balance between ease-of-use and configuration and have a large array of features and possibilities. 
  • Their price / quality ratio is excellent, much more than comparable solutions.

How do the ColorLogic products compare to pure (for example packaging) N-Color workflows?

Advanced packaging products can re-separate files using a flexible number of spot colors. The answer ColorLogic has for such workflows depends on its unique ability to work with MultiColor DeviceLink profiles in CoPrA and ZePrA. Using Photoshop and the edit module in CoPrA, a customer can create custom spot color orders and build those into a DeviceLink profile that can then be used by ZePrA to separate incoming CMYK files. An upcoming ZePrA version will add a much more advanced spot color conversion module for such workflows as well.

In such environments it will be very important to understand the needs of your customer and their project very well before suggesting a ColorLogic product. In case of doubt simply email  and we will be happy to help you qualify opportunities.

Can I create my own test targets?

There is no built-in test chart creation tool. However, besides the built-in charts, ColorAnt and CoPrA support any measurement file that has the reference and measurement data specified in the CGATS prescribed way. A number of the free test chart creators from other companies (such as the MeasureTool from X-Rite or the ColorPort utility) can be used as well.

Does CoPrA support G7 the IDEAlliance control strip?

Yes, the measuring tool used (UPPCT) has a number of predefined control strips built-in and the IDEAlliance control strip is one of those. When cleaning up measurement data, ColorAnt can correct measurement data according to the G7 Gray Balance rules as well.
