The Ugra/Fogra Media Wedge CMYK consists of 72 patches, which are defined with area coverages of the process colors C (Cyan), M (Magenta), Y (Yellow) and K (Black). The 72 selected color patches correspond to the most important patches of the ECI 2002 color chart. Therefore for each patch, colorimetric aim values according to ISO 12647 are defined, depending on the printing proceedure and the printing substrate. Thus the input and output color values are well-knwon and given for the production of proofs and prints. With the help of the Excel file provided with the Ugra/Fogra Media Wedge CMYK, the evaluation of a proof or a print is performed within a few seconds.
