The portal for colour binding proofs, colour proofs, digital proofs, online proofs. Compact knowledge on colour management, graphics, measuring technology & more.
Digital proofs (correct: contract proofs) are an ISO-certified test equipment for the graphic arts industry. Digital proofs simulate the colourfulness of offset or gravure printing in a colour and legally binding manner within the narrow tolerances of ISO 12647-7. Today, they are almost exclusively calculated using a RIP and then produced with inkjet printers on special proof papers.
An online proof (correct: contract proof) is an ISO 12647-7 certified test equipment for the graphics industry. It is called online because it is ordered “online”, i.e. via the Internet.
