ABSTRACT:
Absolute perceptual values are stored in the design lab, for maximum-density-tone cutoffs—preferably a maximum yellow-blue chrominance b* for yellow and minimum luminosity L* for other colorants. Automatic field operations in each printer then force the printer to subsequently print nominal full-saturation colorants so as to match the stored values. In addition to the stored cut-offs, black-and-white reference values measured in the printer are also used in linearizing printer response, for specific combinations of printing medium and printmode.
