XYZ refers to a colour space called ‘CIE XYZ’, which is also known as the CIE 1931 XYZ colour space. CIE stands for the Commission Internationale de l’Éclairage, i.e. the International Commission on Illumination, and XYZ refers to the mathematical coordinates of the colour space. For one customer, we print XYZ-EPS targets in the maximum colour space of our proofing systems. So if you have printed XYZ data, please contact us at any time.
The CIE XYZ colour space is a device-independent colour space that was developed by the CIE to model human colour perception. It is based on the primary colours X, Y and Z and serves as a reference for other colour spaces and colour models. The XYZ colour space forms a link between the physical properties of light and the human perception of colour.
In the XYZ colour space, all colours are represented as three-dimensional coordinates, X, Y and Z represent the brightness and the proportion of the respective primary colour. The Y value represents the brightness or luminance of the colour, while X and Z are the colour coordinates that indicate the spectral component of the colour.
The CIE XYZ colour space forms the basis for other colour spaces such as the CIE Lab colour space (see also the free CIELAB HLC colour atlas, whereby HLC represents a different form of the CIELAB colour space) and the RGB colour space. By converting between different colour spaces, colours can be displayed and reproduced in different systems.
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.

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
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
Shortly after Adobe’s announcement to remove PANTONE colours from their products, PANTONE removed the popular PANTONE Find a Color from their website
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
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
