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.
In the current issue of Fogra News “Fogra Aktuell” Proof GmbH is involved in two places. Firstly, a summary of the Fogra report on our first FOGRA55 certification for seven-colour printing with extended colour space in CMYKOGV appeared. You can also find more information on our FOGRA55 certification on the Fogra website: https://fogra.org/en/press-releases/fogracert-erste-cpc-zertifizierung-fuer-fogra55-cmykogv-330 and on proofing.de: And secondly, there was a report on the completion of the research project for textile digital printing, FOGRA58, in which we were allowed to investigate and test the proof capability of the new textile … read more

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
Whether it’s a large global corporation or a small company, the following often applies to designs or redesigns today: we develop everything for digital first.
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
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
Even almost 9 years after the introduction of the successor colour space PSOCoatedV3, ISOCoatedV2 / FOGRA39 is still the most widespread colour space in Europe. We at Proof GmbH count around 200 jobs from time to time for the German Printing and Media Industries Federation, among others. In the last count, proofs in ISOCoatedV2 accounted for around 68% of all proof jobs at our company. This is a clear sign of the continued widespread use of the colour space. ISOCoatedV2: From the classic colour space to the beacon of the … read more
Peter Jäger is an expert in colour management that reliably works across the boundaries of printers and monitors, web and print – essentially: cross-media.
In this short image video we – the Proof GmbH – introduce us and our work. Find out who we are and what drives us. What do you think of our short film?
In 2021 proof.de was again Fogra certified including Fogra “Spot cert” certification, i.e. for the display of spot colours such as PANTONE C and U.
