摘要
First, the inking behavior of the printing units of a multicolor rotary printing machine is determined by means of test forms. The inking nonuniformities on the test forms are transmitted to the pre-press stage. Using the data about the inking nonuniformities of the test forms, the raster tonal values of the color separations of a printing form are modified in such a way that the inking nonuniformities are compensated locally on the basis of the location of their occurrence in the print on the printing forms or films.
