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.
Digimarc is a digital watermark that can be used to embed information in images, videos or other media. Digimarc watermarks are invisible to the human eye, but remain recognisable to special software or devices. Digimarc is becoming increasingly popular in the packaging sector in particular, as this technology allows the digits of the EAN barcode and more to be applied invisibly to all areas of the packaging. Digimarc and EAN barcode at the supermarket checkout When scanning at the checkout, the checkout staff do not have to search for the … 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.
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
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
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
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
Peter Jäger is an expert in colour management that reliably works across the boundaries of printers and monitors, web and print – essentially: cross-media.
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
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
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
