The portal for colour binding proofs, colour proofs, digital proofs, online proofs. Compact knowledge on colour management, graphics, measuring technology & more.
A Contract Proof is a color-consistent and legally binding proof according to ISO 12647-7 The Contract Proof is currently the highest proof standard with the narrowest tolerances and is therefore considered a “contract” between the proof maker and the printing house.
A Digital Proof (Contract Proof) is an ISO certified test equipment for the graphics industry. A digital proof simulates the colour of offset printing or gravure printing colour accurate binding within the tight tolerances of ISO 12647-7. Today, a digital proof is processed via a RIP and then produced with pigment inkjet printers on special proofing 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.
