Applications for DeviceLink profiles

DeviceLink profiles complement the use of normal ICC profiles. For certain tasks, they produce substantially better results in terms of both quality and the printing process when converting and adapting colors, thus making it possible to specifically circumvent a number of the weaknesses otherwise encountered during color conversion based on an ICC profile. The principal application of DeviceLink profiles is the transformation of "separated" CMYK data to a different CMYK. In this case, either the original separation can be deliberately preserved, or the data can be specifically "reseparated". Practical examples calling for separation-preserving profiles would be adaptation to different papers and printing processes, or limitation of the total amount of color. The aim of reseparation can be to harmonize different separations or to use more black in order to stabilize the printing process and/or save ink.

However, the use of DeviceLink profiles is not limited to CMYK. They also have benefits when converting from CMYK to Grayscale owing to the preservation of 100% black, which would not be possible with normal ICC profiles. DeviceLink technology also offers attractive, new approaches to quality optimization, especially for RGB-to-RGB or RGB-to-CMYK and CMYK-to-MultiColor conversion. The impressive result: pure, highly saturated colors and the same color appearance as for example the original RGB data - in diverse printing processes and using papers with a wide variety of paper shades.

Dynamic creation of DeviceLink profiles

The ColorLogic CrossXColor-CMM permits dynamic creation of DeviceLink profiles, taking various factors into account, such as preservation of the separation characteristics, limitation of the TAC, preservation of pure colors, and simultaneous dynamic gamut mapping. This makes it possible for system integrators to offer their customers special color conversions that specifically address problems in the graphic arts industry, together with other workflow solutions.

Benefits

DeviceLink profiles complement the use of normal ICC profiles, making it possible to specifically circumvent the weaknesses of color conversion based on an ICC profile for certain tasks. The main fields of application are transformation from CMYK to CMYK, and tailor-made conversion or optimization for highly specific purposes. We offer specially compiled, high-quality profile sets for a number of standard tasks and printing conditions (ISO standards, USA standards, newspaper standards, gravure standards, etc.). These profile sets are designed for color conversion from one standard to another, and at the same time permit targeted limitation of the total amount of color, as well as ink optimization.

Key features

  1. Limiting the total amount of color (TAC) for various printing standards,
    e.g. ISO, Fogra, ECI, Ifra, Gravure (PSR), GRACoL, SWOP, SNAP
  2. Optimized color conversion between different printing standards
    These color conversions preserve separations, limit the TAC in accordance with the selected printing standard, and preserve the purity of primary and secondary colors. They ensure smooth transitions in vignettes and permit correct transformation of PDF files. Preserving the separations during conversion guarantees that pure gray tones are not subsequently composed of four colors, and that duplex colors (black + primary color) and triplex colors (black + secondary color) remain pure, their colors nevertheless being optimally transformed in colorimetric terms. In addition, the color appearance of the source color space is optimally preserved in the target color space, because both the paper color and the dot gain are taken into account.
  3. Ink reduction (SaveInk)
    The ColorLogic DeviceLink profiles for ink reduction preserve the separation characteristics while at the same time replacing CMY with black. This leads to far better transformation than classical ICC-based conversion with strong GCR. There are SaveInk profiles for three different intensity levels. The first level optimizes the data for a long, narrow black and is designed to stabilize the printing process and harmonize the separations on a forme. The second level targets good ink saving and the best possible printing characteristics. The third level focuses on maximum ink reduction, but presupposes that the press is perfectly set for the respective printing standard, and that the densities are not varied during printing.
  4. CMYK-to-Grayscale conversion profiles
    When converting CMYK data to Grayscale using ICC printer profiles, a tone composed of pure, 100% black - such as black text - cannot remain 100% black owing to the architecture of the profiles. Instead, it is converted to 95%, for example, depending on the printing process involved. On the press, this leads to rasterizing and thus to unsharp printing results. The CMYK-to-Grayscale DeviceLink Sets retain 100% black
  5. RGB-to-CMYK separation profiles
    Depending on the quality of the printer profile used, conversion from AdobeRGB, sRGB or eciRGB_V2 to the various printing standards can give rise to annoying artifacts in some areas. For instance, smooth RGB vignettes often have a much less smooth structure after conversion to CMYK, highly saturated RGB colors lose their saturation, and losses of definition may also occur, depending on the rendering intent used. Even if top-quality printer profiles are used, vignettes in RGB primary and secondary colors cannot be transformed into pure CMYK primary and secondary colors after conversion. The ColorLogic separation DeviceLink profiles are optimized for conversion of AdobeRGB, sRGB and eciRGB_V2, meaning that the above problems are avoided. In addition, the special ColorLogic rendering intents optimally preserve the color appearance of the original RGB data in the target color space by taking both the paper color and the dot gain into account.

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:”

SmartLink

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!

SaveInk

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.

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.”
