ICC profile optimization for proofer profiles
Exact standards are required for proofing and other high quality applications. Falling outside of tolerances in a pass/fail system requires corrective action. Outside of some high end RIPs, no other method has been available for achieving this level of perfection. By iterating the accuracy of individual colors within the output gamut, incredible precision can be achieved.
MatchPatch modifies an output profile to achieve higher accuracy in the reproduction of logo colors, other spot colors, or pass/fail quality control standard media wedges. One historically has had to compromise with matching the range of spot colors, due to limitations in simple colorimetric gamut mapping. Error can be introduced by reading too few color patches during target measurement, standard device error in target measurement, math rounding errors in profile building and viewing light special considerations.
