CGATS is the abbreviation for ‘Committee for Graphic Arts Technologies Standards’, which translates as ‘Committee for Standards in the Graphic Arts and Technologies’. It is an international organisation that deals with the development of standards and norms for the graphic arts industry. These standards cover a wide range of topics, including colour management, printing technologies, image processing, measurement and testing methods, to ensure that processes and products in the graphic arts industry are uniform and of high quality.
CGATS works closely with other standardisation organisations such as the International Organization for Standardization (ISO) to ensure that the standards developed are accepted internationally and can be applied in different countries and industries.
The CGATS standards play an important role in the graphic arts industry, helping to ensure the quality, consistency and accuracy of print products, colour management systems and other graphic arts technologies.
However, CGATS can also refer to files in which, for example, colours are stored in CGATS format. For example, all measurements of paper whiteness carried out by Proof GmbH can be downloaded with their spectral values in CGATS files from the Proof GmbH shop.
CGATS files usually contain standardised information that is important for accurate colour reproduction and quality assurance in print production. Some of the data that can be saved in a CGATS file is listed below:
- Measurement data: CGATS files can contain measurement data from colour measurement devices or spectrophotometers, which are used to record the colour values of printed products or colour samples. These measurements can be saved in the form of spectral values or XYZ colour space coordinates.
- Colour profiles: Colour profiles describe the properties of input and output devices such as monitors, printers and scanners. CGATS files can contain information about these profiles.
- Colour measurement standards: CGATS files can contain information about reference colours or colour measurement standards that are used to calibrate colour measurement devices.
- Print parameters: In print processes, CGATS files can save parameters such as print colours, ink application, print resolution and other print settings.
- Metadata: Additional information such as creation date, author, purpose and description can be embedded in CGATS files to document the context and purpose of the stored data.
- Reference data: CGATS files can also store reference data for specific colour standards or printing processes.
The exact structure and format of CGATS files may vary depending on the specific requirements and standards of the graphic arts application or industry. These files are important to ensure accurate colour reproduction and high quality in print production.

Proof GmbH 2025 once again Fogra and Fogra “Spot Cert” certified
This year we once again created proofs for Fogra certification and sent them to Munich-Aschheim for testing. With these proof prints, which we print according to three different proof standards and on three different papers, we point out that we not only deliver excellent proof quality through internal quality controls and checks, but that the quality of our proofs is also measured and confirmed by external experts. We have now had test prints certified by Fogra for the 12th time. We have also been “Spot-cert” certified for the display of … read more
PANTONE surveys users online about product and service direction
Today I received an email in which PANTONE asked how it should orientate its products and services in the future. The users were asked which countries, industries and company sizes they come from, but also what PANTONE products should look like in the future and what customers would be prepared to pay for PANTONE services in the future. Question: How much can PANTONE services cost? PANTONE appears to be orientating itself on the PANTONE Connect prices: All price queries have the lowest price category < $ 7,- / month, i.e. … read more
X-Rite i1Profiler no longer supports i1Pro2 and i1iO 2
Anyone who has reinstalled or updated their i1 Profiler app in the last few weeks has been confronted with disturbing news: X-Rite announced directly in the start window that it would no longer support its enormously popular i1Display and i1Pro2 devices. Users of the i1Pro 2 devices and i1iO 2 tables, which are extremely popular in printing and colour management, will be particularly hard hit by the announcement: An investment of €6,000 is quickly consigned to the electronic scrap heap. But what can you do if you own such a … read more
Precise proofing of tonal values of spot colours
In recent weeks, there have been lengthy discussions on the Fogra digital printing mailing list as to whether a research project should be launched to define standardised tonal value gradations for spot colours. What is this all about? In the field of CMYK and seven-colour printing, the definition of clear, printable and proofable standards is well established and has been tried and tested in practice. If the paper or paper class is known and defined, a measuring standard such as M0/M1/M2 has been established and the content of optical brighteners … read more
New PANTONE Formula Guides with incorrect ink formulations
Several errors have crept into the new PANTONE 2023 fan decks. In both the PANTONE Solid Coated and the Solid Uncoated color fans, there are colours for which the new ink formulations are incorrect. In the PANTONE Formula Guide Solid Coated fan 2023, PANTONE 107 C and PANTONE 108 C have absolutely identical ink recipes, as well as PANTONE 113 C and PANTONE 114 C. As the colors differ, this cannot be the correct. Several errors in the PANTONE Solid Uncoated fan 2023 In the PANTONE Solid Uncoated fan 2023 … read more
Incorrect grayscale display in Adobe Photoshop and InDesign
Adobe products are ideal for image retouching and layout and handle RGB and CMYK colour profiles very well. However, when editing and retouching grayscale images, for example for a black-and-white photo book, the experience is quite different. Suddenly, images look completely different in InDesign than they do in Photoshop, and even when exporting the image to PDF, greyscale images are suddenly treated differently. This article explains where the problems lie with black-and-white images and greyscale profiles in InDesign and Photoshop layouts, and how you can work in a more ‘colour-accurate’ … read more
We passed the first proof certification for the 7C proof under FOGRA55
A few days ago Proof GmbH was the first company to be certified for proofing for the new 7C exchange colour space FOGRA55. Fogra has developed characterisation data for extended multicolour printing with the printing colours CMYKOGV – i.e. cyan, magenta, yellow, black (contrast), orange, green and violet – FOGRA55 as part of a research project over the past few years. The characterisation data and the ICC profile Ref-ECG-CMYKOGV_FOGRA55_TAC300.icc have been published on the Fogra website in recent weeks. We have now carried out the certification via GMG ColorProof, as … read more

RGB colour spaces explained
RGB colour spaces are colour systems that represent different hues with the three primary colours red, green and blue. RGB colour spaces are used in digital image processing, photography and computer technology to precisely define colours. The most important RGB colour spaces and their special features are: sRGB sRGB is the most widely used RGB colour space and is used by most monitors, printers and digital cameras. It was developed by HP and Microsoft in the 1990s to create a standard for colour representation on the internet and on various … read more
