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.

New certified proof papers at proof.de
In recent years, various problems have arisen with our previous proof paper supplier. On the one hand, we sometimes had to wait more than three months for paper deliveries; on the other hand, we sometimes had significant problems with batch-to-batch discrepancies, surface defects and much more. After lengthy deliberations, we decided in December to replace all the paper. We therefore received pallets of new paper at the turn of the year, which we are now gradually incorporating into our production. There will be no hard cut, but the new papers … read more
Fogra Colour Management Symposium 2026 in Munich from 24 to 26 February
The most important colour management event takes place every two years in Munich: the Fogra Colour Management Symposium. Once again this year, all professionals are invited to make the pilgrimage to Munich: two days of lectures, discussions and a Bavarian evening await participants. Matthias Betz, owner of proof.de, will also be there again: for many years, he has been taking advantage of the opportunity to exchange ideas with colleagues and friends, learn about new technologies, hardware and software, and talk to colleagues from Fogra, freieFarbe, GMG and many more. In … 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
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
MYIRO-9: New Spectrophotometer from KonicaMinolta in action
Over the last few months, we at Proof.de have been thinking about further improving our already very good colour measurement technology in terms of speed and measurement precision. Relatively quickly it became clear that only two devices would come into question: The KonicaMinolta MYIRO-9, the successor of the former FD-9, or the X-Rite ISIS 2 XL. The starting point: Since we at Proof GmbH have 5 proofing devices, the calibration of targets for profile optimisation is a time-critical undertaking for us. Therefore, we had been looking around for an upgrade of … read more
Cross-media colour management really works
Peter Jäger is an expert in colour management that reliably works across the boundaries of printers and monitors, web and print – essentially: cross-media.
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

Colour deviations in 2023 PANTONE Color Bridge Guides
After Eddy Hagen pointed out in this posts, that there were some major colour deviations between the brand new PANTONE Solid Coated Guide 2023 and the previous version especially for the PANTONE 2635 C, I was curious to lookup the same colours in the new PANTONE Color Bridge Coated Guide of 2023 and compare the colours with the previous version. I measured a dE00 of 8,15 between the two colours that Eddy mentioned, which is really far apart from how accurate PANTONE colours should match between the different PANTONE guides. … read more
