Official reference material for proof comparison
Der Ugra/Fogra-media wedge CMYK is the internationally recognized proof reference standard. Common practice for contract proofs requires that the Ugra/Fogra V2 or V3 media wedge be contained on the print. The resulting measurement values must conform to the nominal ISO 12647 values and the ISO 12647-7 tolerances.
Patch reading of the control wedge is achieved with basICColor catch control.
