All-in-one solution ColorAnt integrates advanced color management tools to deliver the most comprehensive overview of the measured printers’ quality prior to ICC color profile creation. This ColorLogic supplied solution comes in two variations: ColorAnt M (standard printing processes and color spaces) and ColorAnt L (packaging and multicolor market).
Reading errors from the instrument, print errors or other elements (e.g. inhomogeneous data) can disrupt the quality of any data measured. ColorAnt is a stand-alone software for the measurement, analysis and correction of color data prior to ICC profiling. By optimizing both the measurement and analysis of multiple data sets, it allows for the creation of printer profiles without the time and cost-intensive printing of large test charts. The solution comes with a vast toolbox of analyzing, comparing, reporting and viewing features to assist users in pinpointing potential sources of error and recommending the best tools to correct these. ColorAnt helps to optimize every printer profiling tool in the market, whether it is ICC-compliant or not. The solution is lauded in markets worldwide for its accurate analysis and deployed internationally to secure time-saving profile creation.
The solution enables the user to include the necessary corrections in the measurement data. Its effect can be checked in advance of the profile calculation. ColorAnt comes in two variations: ColorAnt M is designed for standard printing processes and color spaces, whereas ColorAnt L addresses the packaging and multicolor market. The toolset complies with all standard measurement data formats (also for export), making it compatible with just about any working environment.

ColorAnt is considered the go-to-market all-in-one solution that integrates various advanced color management tools to deliver the most comprehensive overview of the quality of the printers measured.
ColorAnt is supplied by ColorLogic, alongside the CoPra color profiling and ZePra smart color server solutions.
The View window has some interesting new features which considerably facilitate the evaluation of measurement data. First, there are new channel filters. CMY and CMYK filters have been replaced by new filters that allow an even better combination of individual channels. Combinations of 2, 3, 4, 5 or 6 channels, as well as one and two channels in combination with black, can now be faded in and out. These filters are available in 2D and 3D View.
In addition, the number of displayed color patches is shown on the left, i.e. if you have selected a filter, the number of affected color patches as well as the total number of patches is shown on the left.
Another useful feature is that the 3D view now displays the color information of a patch/color point (like color name, device value, Lab value) when moving the mouse over that color point. At the same time, the point is highlighted to avoid confusion when points are close together.
The default color space for the 2D and 3D view can be set in the Preferences dialog in the File menu. Available colorspaces are Lab, LCh, YXZ and Yxy.
The Compare mode of the Compare window has been extended. It is now possible to select the color distance formulas Delta- L, Delta-C and Delta-H from the Compare Mode drop-down menu, which is particularly helpful when evaluating proofs.
Furthermore, the CMY and CMYK filters of earlier versions have been replaced by new filters in the Color Comparison window and individual color channel filters (as in the View window) have been added.
An additional new feature is the comparison of measurement data containing a differing number of color patches. To do this, choose the two measurement data sets in the main window and select the Intersection function from the context menu or click the newly added button (with the gear symbol) to the right below the measurement data list.
ColorAnt then searches both files for color patches with identical device values and removes all other values. Now you can compare the two newly created files in the Compare window.
The context menu now contains additional new options that can be very convenient if required:
ColorAnt now allows the creation of CxF/X-4 test charts. Open the Custom Chart tool, select the required number of channels, name the color channels accordingly, activate CxF/X-4 Wedge under Mode and select the desired Number of patches. Here you can choose between Small, Medium and Large. After you have named the colors, click the Start button and ColorAnt creates a CxF/X-4 chart including a black gradation.
Additionally, two Idealliance charts have been added to the list of predefined charts, available under File > Open Predefined. Both, the Idealliance ISO 12647-7: 2013 control wedge Idealliance-3-Row-Digital-Control-Wedge® and the test chart Idealliance-P2P5-G7- TC® are registered trademarks of Idealliance.
But that's not all on test charts. The new function Patches from image allows you to create an image-related test chart based on a loaded image. It can be accessed via the context menu or by dragging and dropping TIFF or JPEG files into ColorAnt's main window. In the Patches from Image settings screen, select the number of desired patches for the test chart and whether the corner points should be added as well.
The modified Edit primaries tool has three new functional enhancements in addition to a clearer appearance. First of all, you can now exit the tool without losing any of the edits you have made. For example, if after a few edits you notice that you forgot to load a required file into ColorAnt, you can exit the tool, load the file and return back without having to make these edits again. Just choose Cancel - ColorAnt will remember the edits made until then - and leave the Edit primaries tool. Restore these edits after you return by hitting the Restore button. You can now continue your work where you left off.
When a new channel is added, the checkbox Linearize new channels using ISO 20654 (SCTV) becomes available. When activated, the gradients of the newly added channels are linearized according to the ISO 20654 (SCTV) standard. The checkbox is also available if reference data are loaded without measurement data. If channels of another data set are selected and the checkbox is activated, all channels are linearized according to ISO 20654 (SCTV). Otherwise the original gradations of the loaded colors will be used.
Finally, there is the Search function, allowing you to search for specific colors in large color libraries such as Pantone. It is available in the context menu by clicking the pipette symbol when replacing a color.
In addition to the changed layout - the control panels are now arranged in landscape format to better visualize the curves - the Protect Lights (%) slider now affects all three correction functions.
Another very useful feature is the ability to export correction curves as Photoshop gradation curves (ACV) and as XML according to ISO 18620. The curves are automatically saved in the folder /Users/USERNAME/Documents/ColorAnt/Linearity on MacOS systems or C:/Users/USERNAME/Documents/ColorAnt/Linearity on Windows PCs. These curves can then be used either in Adobe Photoshop or any external RIP software that supports the ISO 18620 standard.
The Color Editor has been improved to include a number of functions that facilitate working with large data sets.
There is now a Search field below the table of colors to find and edit specific colors of large data sets. Just type in the name of the desired color and the list will show only colors with those name components.
The color table can be sorted by Color or dE00 (Current) by clicking on the column headings. The newly added Invert Selection button makes it possible to reduce a large number of displayed colors of a large data set to only a few colors. Simply select the desired color patches, click Invert Selection followed by the Delete button. Now you are working on your individual color selection.
Additionally the Color Convertion Modes were extended by three options.
The ICC Transformation window has been optimized. Besides the possibility to select an ICC profile from the drop-down menu, it is now possible to use a profile that is not in the ICC profile folder of your operating system. For example, if you have a profile, which you would like to use, on the desktop of your computer, you can simply drag and drop it onto the drop-down menu. If it matches the selected data, it will immediately appear in the drop-down menu.
Extraction of original measurement data from an ICC profile: This functionality imports the original measurement data from ICC profiles. If you created or updated a profile with CoPrA using the Measurement Processing options Brightener Compensation and/or Measurement Correction, CoPrA stores two data sets inside the profile. The original measurement data (raw data) as well as the corrected data used for profiling (profiling data). ColorAnt extracts both data sets naming them accordingly when opened or when an ICC profile is dragged to the ColorAnt window.
New chart selection:The Chart tab has been removed, the charts list can now be accessed via the
File menu using the entries Recently used files and Predefined Charts.
New Virtual Device (manual):A new manual Virtual Device has been added to the device list, which allows to manually enter Lab values for selected patches.This is helpful, for example, if the device that measured the values is not connected to the Measure Tool or if an older device is used that only displays the measured values on the device itself.After connecting the device, a dialog with an input field for the Lab values appears. Enter the appropriate Lab values and either press the enter key on your keyboard or click the Next button to automatically select the next patch.This allows all required lab values to be entered in a single session. Once editing is complete, click the Close button to finalize the manual measurement process.
Measuring multiple charts: It is now possible to measure multiple charts in a single session (without closing/opening the Measure Tool after each measurement). Measured charts are automatically added to the Measurements list.The number in brackets indicates the number of measurements.A previously measured chart can be added to this list by using the Plus button which is only enabled if a complete measurement data set is available. Clicking on Measurements opens the list containing all measurements. If a device with a wizard (positioning) is used, e.g. the X-Rite i1iO, the next measurement can be started by clicking on the Gears icon to enter the wizard/device settings. Clicking the Transmit button transfers the data directly to ColorAnts Data Sets section and the Measure Tool is closed.
The Measurements window shows a list of all the measurements that were added in the current measuring session.The chart selected in the list is shown in the Measure Tool main window.The list contains the following information:
Remeasure faulty patches/lines: Existing measurement data with erroneous measurement data can now easily be corrected by simply remeasuring the faulty parts (lines or patches) of the chart. Just load a previously measured chart, and it is automatically added to the Measurements list as Imported data. If a file with multiple measurement conditions is loaded, select the appropriate Measurement Condition from the import dialog. Connect the measurement device and measure the faulty lines or patches. If a device supports the chosen measurement condition only in a combined multi measurement mode, the data of the selected condition will be copied into all condition slots. Once the remeasurements are completed, the measurement data has to be added to the Measurements list using the Plus sign. Click on Transmit to transfer the data back to the calling application.
Please note that we provide version 5.1 as a free upgrade to ColorAnt 5 users!
In ColorAnt 5.1, all ICC profile drop-down menus now function as search fields. Simply type in some letters of the desired profile name and only those profiles containing these letters will be shown in the drop-down menu. This is a feature power users will love and that has first been implemented in CoPrA 5. Ticket #180805
ICC allows creation of profiles with up to 15 channels. Consequently, ColorAnt allows the user to load and save test chart measurement data with up to 15 channels. If data with more than 15 channels is to be loaded, a warning is displayed as such data cannot be opened.
Note: This does not affect spot color data. It is still possible to load spot color measurement data containing thousands of colors.
The Custom Chart tool now automatically adds redundant patches for paper white and primaries in generated profiling test charts. This allows better verification of printer stability and results in better averaging and redundancy correction of profiling test charts. Redundant patches are added only in medium and large size profiling test charts containing 2 or more channels..
Note: We recommend to randomize the patches over the entire layout of the test chart using the Export Chart tool with Patch distribution set to Randomize before printing.
The Report feature now sorts the ICC profiles in the drop down menu under Compare with print standard (profile) by percentages with the highest match on top.
The labels of generated test charts from Export Chart are now consistent with the display of the Measure Tool and the data exported by ColorAnt.
A new warning message has been added in the History Log for Edit Primaries in case manually entered Lab values cannot be realized. The reason is that some Lab values are no real colors and do not have a spectral equivalent.
Support for the X-Rite Ink Master file format (MIF) of the X-Rite ColorMaster software. ColorAnt can import such data but can’t export it as *.mif. Export to other supported file formats (see online help Main Window/File) will work.
A special feature in CGATS files is that they can contain different specifications in one file, e.g. measurements from different test charts or different color spaces. ColorAnt now supports multiple tables in CGATS files. A typical use case would be the export of various spot color Lab values from the Spot Color Report feature in ZePrA and their import to ColorAnt for further inspection.
The display of channel names under Optimize Output Values in the Color Editor tool has been changed from rows to columns. This provides a view consistent with ZePrA and other channel tools.
With the new function Include black gradient in export, the black gradient can also be exported. Typically, when exporting CxF/X-4 data from a complete test chart, only 100 % black and overprinting spot colors with 100 % black are added, but not the black gradient. However, adding the black gradient can be very helpful when using CxF/X-4 data in Edit primaries or other tools to extract the black information.
Note: The CxF/X-4 specification does not explicitly prohibit this, but the original idea is to specify spot colors rather than black. Therefore, activating the checkbox could cause incompatibilities with programs from other manufacturers.
The new version – Measure Tool 2.1 – brings three major changes that improve how the software works:
ColorAnt 5 is a major upgrade containing many new features and improvements of existing tools requested by customers. ColorAnt 5 makes the newest standards, like ISO 20654 (SCTV) or CxF/X-4, more accessible to users and includes even more powerful tools that color managers will find beneficial. In addition, on macOS systems ColorAnt 5 runs in 64 bit mode making it future proof for recent and upcoming macOS versions.
ColorAnt 5 features a powerful new color editing tool. It can be used to edit color patches and to process color conversions of spot colors. Some of the new features will look familiar to ColorLogic ZePrA users who already know the advanced spot color conversion of our color server.
Color Editor allows the user to:
To convert spot colors to a desired target ICC profile, first load the measured spot colors into the ColorAnt Data Sets section, e.g. a Pantone spot color library (or any supported file format such as CxF), then click on Color Editor. The appearing window contains a scrollable table on the left showing all spot colors of the file and the editing options on the right. Select an ICC Profile from the drop down list and a calculation Mode.
Three modes are available for the color conversion:
The preset dE00 Limit highlights colors in the table with a warning icon that exceed the threshold defined by the user.
If a color is selected from the table, the device color values for each channel of the selected profile are shown under Optimize Output Values and the deltaEs are reported under Color Information. As a default, the device values calculated via the ICC profile are shown without any optimization.
By clicking on dE76 or dE00 the deltaE can be minimized for each color. Clicking on Automatic applies the selected ColorLogic calculation Mode which typically results in a reduced amount of channels for better printability. Users can optimize each individual color or a bunch of colors and can even enter device values manually. Single or multiple colors can be selected and optimized.
By clicking on Start, the entire list of colors is generated in the Data Sets section including the calculated and optimized device color values. Those values can be saved for further usage in other applications in any format supported by ColorAnt (CGATS TXT and XML, CxF3, Adobe ASE and ACO, named color ICC profile or GMG CSC).
Note: ColorAnt 5 supports the Adobe Swatch Exchange format ASE.
The CxF/X-4 file format for spot color characterization is gaining momentum in the industry. Previous versions of ColorAnt already supported the export of data in this format and were able to extract spot color information from PDF files be it CxF/X-4 or others.
Version 5 features a new tool in the Data Import/Export section which allows CxF/X-4 spectral information to be embedded in PDF documents.
To do so, first select the CxF/X-4 measurement data, then open the Embed CxF/X-4 tool and select a PDF/X file with spot colors to embed the selected measurements into.
The tool lists all spot colors of the PDF/X file, checks for spot color names that fit those of the CxF/X-4 measurement data and warns in case of conflicts. Only if the spot color names of the PDF file fit those of the CxF/X-4 file will the spectral data be embedded when clicking Start.
Note: The tool is only available with a ColorAnt L license and if the selected measurement data contains spectral data and if it is compliant with the three CxF/X-4 spot color conformance levels:
ColorAnt’s History feature is a helpful tool that records every editing step. It allows the user to switch between different processing states of a file. After some editing and data optimization with various tools users often cannot remember the settings (slider settings or options or files) used. The new Save History Log – available at the bottom right of the main dialog – saves all activities that have been applied to all files as a comprehensive PDF document.
In addition, when double-clicking an entry of the History section a dialog pops up showing the settings applied to the data at this specific step. This single step can be saved with Save Log. The new log feature has an additional advantage when averaging files using the Averaging tool. The averaging log contains a detailed report with sample colors (known from our general Report feature) comparing the averaged data to all files and providing useful statistics for process control such as standard deviations (sigma, 2 sigma, 3 sigma) for Density, dE and dH/dL. This allows the user to recognize colors with large deviations which would not be so obvious by just looking at the values in the averaged file.
The Tone Values correction tool which corrects data according to different technologies like G7 or ISO 20654 has been improved. For multicolor data, a fourth option was added which only adjusts the multicolor channels to ISO 20654 and leaves the CMYK channels untouched: ISO 20654 (Multicolor). This is a useful option for those who have calibrated the CMYK parts according to other standards, like PSO density curves or G7 and just want to adjust the additional multicolor channels to match ISO 20654 (SCTV) requirements.
In addition, a Protect Lights slider has been added which was previously available in the Correction and Smoothing tools. This helps users to leave the highlights untouched when applying G7 or ISO 20654 corrections. It is especially helpful for Flexo customers as it avoids over compensation of dot gain in the highlights.
When viewing measurement data, the View Options in the 2D and 3D tabs have been updated with additional color channel checkboxes for the primary colors available in the loaded data set. The color channel checkboxes can be combined with the above color filters so that only the Multicolor Primaries or Secondaries can be shown. This greatly facilitates finding and viewing patches. The removed viewing options, Duplex and Triplex known from previous versions of ColorAnt, can be compensated by selecting appropriate color channels individually (e.g. Cyan + Black shows duplex combinations and Cyan + Magenta + Black shows triplex combinations). Both options were removed to gain space in the user interface. In addition, the filters work in combination with the color channels. If, for example, the checkbox Secondaries is enabled, the checkboxes Primaries and White are automatically enabled. They can be disabled if only two color combinations (Secondaries) are to be highlighted.
The TVI tab allows users to switch between the typical density based dot gain curves according to Murray Davies or the modern colorimetric dot gain curves according to ISO 20654 (SCTV). Linear dot gain curves according to ISO 20654 would show a straight horizontal line.
The Curves tab now allows the user to view the linearity curves of all or single primary gradations in a single graph. In previous versions, only a single curve of one primary was shown. Switching between Curves and TVI tabs allows users to view either the tone value increase (TVI) curves or the input-output value curves based on the Method chosen under Curves. A linear dot gain curve according to ISO 20654 would show a straight 45 degree line in the Curves graph.
The CIE Conversion tool allows to convert spectral remission data with a different Illuminant and a different Observer angle. It is now possible to directly measure the ambient light using supported instruments (X-Rite i1Pro and Konica-Minolta FD-7) from within the CIE Conversion tool. The Measure Tool v2 – which can be started from within the tool – supports a new ambient light measuring mode. In previous versions, an external application had to be used for measuring and saving ambient light measurements. The measured ambient light reading can be saved separately for later use.
In Measure Tool v2 and higher a Measure Mode has been implemented. This allows to switch between Ambient Light Measurement mode with suited instruments and the standard Reflectance Measurement mode. If an instrument such as X-Rite i1Pro and Konica-Minolta FD-7 supports both modes a light bulb button is shown in the user interface. Clicking on this bulb button will switch between the modes. Alternatively users can switch the mode in the file menu Measure Mode.
Various improvements and better support for the instruments (X-Rite i1iO and Konica-Minolta FD-9) have been implemented. For example will the Export Chart tool save chart, patch and gap sizes and Measure Tool reads such information for easier set up of the instruments measure wizards. This way user intervention can be minimized leading to less errors when measuring.
The Edit Primaries tool extracts a wide range of measurement data from a selected data set via the eyedropper functionality, such as the full tone, the gradient and overprints on black – all spectral data of course but Lab is also supported. If the selected data contains color overprints with other primaries, such as secondary colors, this will now be taken into account, too. The new checkbox Adopt Secondaries allows the user to take advantage of those additional measurement data. The option is only enabled if secondary colors are available in the picked data set and at least two colors are exchanged. A tool tip indicates the selected overprints and the associated data sets. The option can be disabled if the measurement overprints are not suitable for the given data, in which case Edit Primaries will calculate the overprints itself.
Using color overprints can improve the accuracy of the rendering and calculation of the spectral color model.
The Custom Chart tool now allows to build test charts with up to 9 channels. This extension reflects the technology improvements in multicolor profiling recently introduced in CoPrA 5. Using ColorAnt 5 it is possible to create multicolor test charts with two gamut extending colors in each color sector, e.g. a 6 color chart with CMYK+Red+Orange, where Red and Orange are two colors extending the gamut in the Magenta and Yellow color sector.
Additionally, several technology improvements regarding the distribution of patches – for example in the Flexo Profiling mode – and the addition of interstitial color patches for multicolor charts result in further quality improvements of the new Custom Chart tool.
The main new addition to the Export Chart tool is a large preview section on the right. The preview shows the color distribution on each of the generated pages. This is quite powerful as it allows to recognize changes in Chart Dimension, Patch Sizes and the selected Options.
The Patch Sizes panel introduces a new setting to Prevent vertical gaps. Depending on the chart size this allows to fit one or more additional rows on a page.
The preset handling has been optimized and a new sweeping broom icon has been added next to the drop-down menu Preset to delete edited presets. In addition a new preset for the X-Rite i1iO with a minimum patch size for single mode measuring has been added.
The Report feature is a helpful tool to compare the measurement data to a selected profile and optionally to the best matching profile. When comparing profiles the matching accuracy is now shown for each profile of the drop down list in percent, so now it is much easier to find a profile that best fits the measurement data. In addition, the best matching profile will automatically be selected in the profile chooser if the Search button is clicked.
A new Layout feature is available in the context menu of the Data Sets section for a selected measurement file. It allows the change of the rows and columns of a chart in terms of amount of patches in Width and Height.
For example, in the Layout context menu users can define the number of rows of a chart.
In addition, new context menu options to Add, Copy and Paste patches in the 2D View have been added. Along with the already available tools Edit and Delete this allows the fine tuning of single patches of a data set.
Note: The channel sequence of a CMYK color space does not have to match the printing sequence. For example, the printing sequence KCMY is quite typical in web offset presses, however, the channel sequence should still remain CMYK as some programs can’t handle untypical channel sequences correctly.
Note: Even if it is not yet possible to create reference files for test charts with more than 7 channels with ColorAnt 4.2, a correctly structured test chart can still be created from an 8-color reference file using Export Chart. Typically, the channel names and colors from the information of the reference file are used in this process. If this information is missing, it may result in unfavorable test charts and channel names may only be assigned generically, for example, channels may be named Channel 1-8.
The Edit Primaries tool has been updated to allow the assignment of new color values to device values (DCS values) which do not already contain color values. Thus, new characterization data can be created which is based only on existing wedges of primaries or on the input of Lab values. There is no longer a need to reprint test charts.
A feature to automatically optimize and remove redundant color patches has been added to the tool Export CxF/X-4 in the File menu (to save CxF/X-4 compatible measurement values). If the checkbox Remove Redundant patches is activated all required color patches will be saved only once in the exported CxF/X-4 file, avoiding duplicates.
The compatibility to CxF measurement values of different manufacturers has been optimized.
The Link tool has been redesigned and one new option added. There are three options available now in the Link tool. The options are grouped with radio buttons that are enabled and disabled according to the chosen files.
Channel re-ordering in Edit Primaries The Edit Primaries tool can be used to exchange, add and delete channels in a measurement data file. With ColorAnt 3.2 and higher it is possible to reorder the channels without changing the measurement data. One example is if you add Orange as a 5th channel and Green as a 6th channel to a CMYK data set.
But later on you decided that the channel order should be CMYK+Green+Orange. Now you can simply exchange the channel order by using the pipets icon and selecting Orange for Green and Green for Orange from the same measurement data file without the measurement data changes. If channels are only reordered this will be indicated with adding ChannelOrder to the file name.
Note: The channel reordering feature in Edit Primaries and the new Link tool Merge by Channel Name can be used to prepare multicolor measurement data from different origins. For example it allows to combine the four separate 4 color Esko Equinox files to a 7 color multicolor data set to be used for profiling in CoPrA.
The CxF3 file format has been supported since a longer time in ColorAnt already. With ColorAnt 3.2 we support to load and display CxF/X-4 data for spot colors, too. Saving as CxF/X-4 is not yet possible in ColorAnt.
Note: CxF stands for Color exchange Format. CxF files shall be used to communicate color vendor neutral. CxF/X-4 is an ISO standard since 2015 and has been designed to define spot colors by measuring and storing spectral information of ink solids and tints, on substrate and process black. This spectral definition allows color management systems to better proof and reproduce spot colors.
The dialog before creating the data reports as PDF or XML file have been changed. The dialog new with added features.
In addition to the two options to Check the measurement data quality and to compare the data with a different profile (Check print standard), there is the choice of two DeltaE methods for the evaluation. You have the choice to either select the conventional method DeltaE76 or the modern DeltaE2000 method. In addition, you can Search from your list of ICC profiles on your computer which profile fits the data best. The percentage of compliance is displayed behind the profile name. If required you may select this profile in the drop down menu of the Check print standard option to compare the data. In the new version of ColorAnt 3.1 multicolor measurement data can also be compared to your existing multicolor profiles.
However, most of the changes are in the new PDF report that is created by clicking on the Save button and define the file name. The report now offers even more useful information, provides an overview of the quality of your measurement data, and recommends what kind of corrections should be applied. In addition, the suitability of the used test chart is checked, as well as dot gain, linearity, and spider web diagrams are shown and the conformity or nonconformity to a print standard (ICC profile) listed. The PDF report is an excellent documentation of the measurement values of your print run, too.
A vivid example of a PDF Report featuring the new ColorAnt report layout can be found here. It compares the new characterization data FOGRA51 (PSO Coated V3) with the ISO Coated V2.
Note: In addition or as an alternative to the well designed PDF report with graphics and tables, you may also create a ColorAnt XML report with the pure data. The corresponding TVI values, comparisons and DeltaE evaluations are listed in a XML structure. A XML report is useful if you want to create a separate report in the specific layout or with other evaluation priorities.
ColorAnt 3.1 enhances the capability to create and reorder test charts for 3rd party tools with the Swap Rows with Columns feature. By right clicking on the data set, six options are available. This feature will enhance compatibility with third party software.
Note: Open the 2D-View to verify the results of the reordering applied. If there is an issue with reordering simply click the History entry to revert the data.
Another similar task to the reordering is that some third party tools save the measurements without the reference data. Without reference data, neither ColorAnt can work with the measurement data nor can CoPrA create an ICC profile. In order to combine or link the separate reference and measurement data files they must have the same patch count. Simply load both files in the Data Sets section select them and click the Link tool to combine them to one file.
The tool for the editing of primary colors works with spectral data and uses complex mathematical calculations. This may take a little while especially when using large test charts with many channels. For this reason, a progress bar has now been incorporated in the dialog which shows you the current status of the calculation.
When replacing the Substrate or Paper white, this change does not affect the primary colors. This is done on purpose, because the tool is intended only for smaller paper white changes from which the full tone of the primary colors would not be effected. For this reason, additional information will be displayed in the dialog. If you want to make major changes to the paper white, we recommend that this should be done before editing the primary colors with the White Correction tool.
Until now, only primary colors could be exchanged with other colors when the reference and measured values for the color to be replaced were present in the loaded data file. With spot color libraries such as the Pantone libraries, which can be opened as a CxF file in ColorAnt, there are no reference values. Therefore the exchange was impossible in former versions. With ColorAnt 3.1 you can use these spot color libraries for the exchange of primary colors. Each spot color in the library is interpreted as full tone and can be selected to replace a primary color.
Note: If only the full tone for the exchange of a primary color is available but no gradation values, ColorAnt will use the gradation behavior of the original primary color.
The White Correction tool is predicting the impact of paper white changes to the measured values of a test chart. With ColorAnt 3.1 there are three different methods to calculate this effect. ColorLogic Default is still recommended as the default setting. The two other methods available are ISO 13655 and Relative colorimetric.
Relative colorimetric effects are strongest because paper white changes will modify the entire color space. In case of major changes in the paper white this will also massively effect the primary colors. The ISO 13655 method is still similar in the highlights and colorful primary colors to relative colorimetry. However, this method assumes that the shadows and very dark colors are not changed. The ColorLogic Default method, we proceed like in ISO 13655 and assume that the shadows are not effected and that there is a much lower impact on the primary colors. Due to our experience this corresponds more to the real observation.
The CxF3 file format is predominantly used for exchanging spot colors. ColorLogic has improved the CxF3 import filters to be compatible with the recent ISO standard 17972-1:2015. In addition, a second ISO standard, 17972-4:2015, for the exchange of spot colors with tints. ColorAnt also supports the import of compatible with CxF/X-4 files.
Note: Older CxF versions are no longer supported by ColorAnt.
For the first time ColorAnt 3 will be available in two packages: ColorAnt M and ColorAnt L.
The tools to edit and modify measurement data are organized in groups in a vertical tool bar on the left hand side. Active tools that can be applied on measurement data are recognizable due to their colorfulness whereas tools that can’t be used are grayed out. At the bottom of the tool bar you directly navigate to the Registration dialog for loading and requesting licenses and to edit the basic setting of the applications in the Preferences.
The Edit Primaries tool allows the user to add, remove, and exchange primaries or the paper/substrate into an existing measured test chart. In typical print production, adding or swapping ink(s) requires the expense of printing a full blown test chart. The Edit Primaries tool will simply require the spectral data of the new ink(s) to be added or exchanged. Edit Primaries will not only exchange the inks but also recalculate all overprints based on intelligent spectral color models and generates new measurement data. With this extraordinary tool you are immediately able to create all required data for calculating ICC profiles for modified color combinations.
Potential efficiency gain with the Edit Primaries tool in typical production scenarios are:
Note: To add channels a ColorAnt L license is required.
Note: To remove channels a ColorAnt L license is required.
Note: Another feature of Edit Primaries is to use this tool to extract the primary ramps of one channel. Simply disable all checkboxes except the one channel you wish to retain.
The Export Chart tool allows to create test charts based on device color values, which can be stored as TIFF or PSD files to be printed on a printer.
Measuring instruments may have specific needs regarding patch sizes, the gap between different patches and probably regarding the size of the overall chart. In addition you may respect the requirements of your print process and eventually reduce the Ink Limit (TAC).
In the lower area you may define Patch width and Patch height of each color patch. In addition you may chose in the Drop Down menu if a Patch delimiter is required. Use Auto as a default or None if no gaps between patches are needed. For further information consult the documentation for the instrument.
The Patch distribution gives the user the option to either print the patches as defined (Normal) or Randomize the patches (better for press profiling). The setting Sorted will arrange the color patches from light to dark. This might be helpful to modify a random chart into a well sorted layout or if you may export a color wedge of one single color.
In the upper part you should define image size and TAC of each individual test chart. Enter the desired Chart width and height to limit the space that might be used for the color patches (minus the space requires for labeling the patches). Do not mix this with the paper size – it is similar to the image size. The exported test charts can be positioned on the required paper size afterwards and then be printed.
Note: Please consider the documentation of your measurement device. Some measurement devices allow measurement rows of patches by swiping over the rows. Those types of devices use rulers that can measure up to a certain width which need to be taken into consideration when the Chart width is defined, if a patch delimiter is required and will inform you about the minimum patch size.
The Ink Limit is a specific feature in Export Chart and allows to limit the TAC for the exported test chart. Typically each of ColorLogic’s CMYK and multicolor test charts have patches with a maximum of 400% ink. If a 400% ink limit is too high for the press or the user would like to define an other ink limit he can enter the desired Ink Limit. ColorAnt uses a sophisticated ink limiting algorithm that does not simply clip values.
Note: Use the exported reference file for measuring and profiling so that reference values and test chart fit to each other. Please note that the reference file will not be ink limited too, otherwise profiling would be leading to incorrect ICC profiles but it might be that third party profiling applications can’t handle this. In addition, when building the ICC profile either use the same or a lower ink limit (called Max.Ink in ColorLogic CoPrA) than defined in the test chart. In most cases an ink limit is not necessary for test chart creation.
To define a custom test chart for profiling a reference file containing the device data for the color space is required. The Custom Chart tool is designed for creating the reference files for test chart generation. Custom Chart allows you to generate reference files for the following color spaces:
Afterwards create a pixel file, either in TIFF or PSD format, from the reference file by using the Export Chart tool to be printed on your device and Measure the test chart with a spectrophotometer.
The following description will show you how to generate a reference file by using the Custom Chart tool. Depending on the color space different options are available. To generate multicolor reference files an additional multicolor license is required.
Note: A ColorAnt3 L license is required to do this.
To generate a generic multicolor test chart decide on the number of channels and their names (with or without CMYK), so that it is as close as possible to the used colors on your printing machine. It is not necessary to define the channel colors in the reference data exactly. Just make sure that you are close to the kind of color so that the correct color combinations will be generated. For example, if you want to print a violet, you may chose blue as the channel color, but not green or red or cyan.
Note: In ColorLogic CoPrA multicolor profile creation three chromatic colors + optional black + a maximum of three gamut expanding colors are supported. Some examples for possible combinations are: CMYK+Orange, CMY+Green+Blue, CM+Orange+K, CMYK+Red+Green+Violet etc. Other colors positioned within the CMYK color gamut may lead to problems in profile creation. Use the Spider Web in the View dialog to check for problematical color combinations in your measurement data.
The CIE Conversion tool allows changes to the Observer from a standard 2 Degrees to a 10 Degrees observer and changes the Illumination from the standard D50 light source.
Note: The CIE Conversion tool can only be used with spectral data.
The Illumination drop-down menu contains several options. Printer profiles are typically created for the D50 viewing condition. However, if it is required to set up photos in a gallery illuminated by the light of incandescent lamps (corresponding roughly to light source A), or displays at an exhibition where the lighting conditions might be challenging (e.g. fluorescent light), you can take the lighting conditions into account. You can either select one of the three predefined viewing conditions, or enter the measured viewing condition manually in the form of a Kelvin or an XYZ value. ColorLogic has added the Emission option as a powerful new tool to customize illuminations. The Emission option allows the user to select spectral emissions readings of a specific light source by either loading a CxF3 or text file. To simplify it even more, you may drag-n-drop a measurement file with the measured light onto the value field, where upon ColorAnt extracts the white point from the file and displays the value.
Note: If there are multiple readings of the same light source ColorLogic recommends averaging the measurements by using the Redundancies tool first, save the data and then load the emission reading in the CIE Conversion tool.
Applying the CIE Conversion tool by clicking the OK button will result in a measurement file containing only Lab values. There fore your spectral data will be converted to Lab data using the observer and illumination of your choice. Use this data to build your printer profile in ColorLogic CoPrA.
Note: Always apply the CIE Conversion tool as the final step due to the conversion to Lab data.
The newest installers of the ColorLogic products contain a new version of the measurement software UPPCT version 2.3.
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.
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.
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.
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.
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.
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.
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.
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.
“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.
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!
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.
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.
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.
“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:
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.”
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.
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.”
callas pdfToolbox is capable of doing color conversions using regular ICC profiles, but it can also use DeviceLink profiles.
Using specially crafted DeviceLink profiles from ColorLogic is an affordable way to reduce ink in PDF documents to what is needed for a specific printing purpose.
