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 (correctly: contract proof) is an ISO 12647-7-certified testing device for the graphic arts industry. A digital proof simulates the colourfulness of offset printing or gravure printing in a colour and legally binding manner within the narrow tolerances of the ISO standard.
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.
