The term metamerism is understood as the effect that two things may look the same under one light, but completely different under another light.
In practical terms can be mooring at an example: If a yellow sheet of paper and a sheet of white paper under yellowish light are considered, both appear the same. If the same sheets are viewed under white light, one sheet is white, whereas the other sheet is yellow, so a completely different colour.
This metamerism can especially occur very strong, if different colours and methods are used for the production. The gray of a proof is often made of several inks of the 11-colour proofing systems, while a neutral gray in an offset print ist often made from only one colour: black. The risk of colour shift is therefore higher for the proof than for the pure black in offset printing. Even in colourpatches of fabrics and prints strong metamerism may occur.
Lighting can also be a reason for metamerism. A perfect proof-to-print-match unter D50 standardized light might well be, but under sunlight with UV influence or incandescent light in the evening there can be huge colour deviations because of metamerism.
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
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
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
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
From now on you can order proofs for metal decor printing on white sheet metal at proof.de: The ICC profile for Fogra60 is Metal-Printing_MPC1_FOGRA60.icc
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 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 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?
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
