ABSTRACT:
A three-color offset printing machine produces, during the printing of sheets, color measuring strips with several color measuring fields. A gray half-tone field produced by the overprinting of three colors serves as the reference field. The color location of the reference field is compared in a color deviation computer with the color location of a correlated desired reference field. From the color deviation, a layer thickness variation computer calculates a layer thickness variation control vector by means of a sensitivity matrix calculated on the basis of a linear model by a matrix computer. The matrix computer evaluates a series of secondary fields comprising three single color half-tone fields, three single color full-tone fields, three two-color full-tone fields, and a three-color full-tone field.
