CxF stands for “Color Exchange Format”, an open XML format for the exchange of colour information, which is increasingly being implemented by software manufacturers to attach information on the colour behaviour and overprinting behaviour of spot colours to PDF files, for example. This information can then be read and interpreted by proofing software to optimize colour reproduction in a proof.
Ideally, the CxF/X file then describes the spectral measurements of the spot colours (on paper white and, to determine transparency, on black) and is used for colour communication and data exchange between customer, designer, agency and printer.
For the freieFarbe e.V. CIELAB HLC Colour Atlas the achieved spectral values of all colour fields are published as CxF3-file which can be used e.g. by colour manufacturers and software like InkFormulation from X-Rite.

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

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
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

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