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.
PSO stands for “ProcessStandard Offset Printing”, a standard that was developed by Fogra and the German Printing and Media Industry together. The ProcessStandard Offset Printing is a set of standards for offset printing. With test equipment and control by measurments as described in the PSO, the printing process of the data delivery and data preparation on the platemaking is monitored, controlled and checked.
