A colour is described as opaque if it is non-transparent or impermeable to light. As a rule, this means that light cannot shine through the colour and no objects or colours are visible behind it.
The opacity of a colour depends on various things such as the type of material or medium used, the thickness of the paint layer and the type of paint. Some colours can be naturally opaque, while others are the opposite of opaque, namely transparent or translucent.
Opaque colours are used to achieve an impermeable and opaque effect. They are used, for example, in the design of art, in prints or in the application of paints and coatings to achieve complete coverage and uniform colour reproduction.
The opacity of a colour is also associated with terms such as transparency, translucency and see-through.

MYIRO-9: New Spectrophotometer from KonicaMinolta in action
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
Proof GmbH 2025 once again Fogra and Fogra “Spot Cert” certified

Proofs with Digimarc EAN codes and verification
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

X-Rite i1Profiler no longer supports i1Pro2 and i1iO 2
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
New certified proof papers at proof.de
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
