The Relationship Between Ink-Film Thickness in the Color Reproduction and the Design of the Photomechanical Process.

An experiment is described in which the magenta and yellow ink-film thicknesses were varied in a four-color lithographic process. Compensations in tone reproduction and color correction were made on a scanner for the changes in ink-film thicknesses, so that closely matched reproductions resulted. An insight was gained into the important factors one should consider in selecting ink levels, which could lead to improved quality and savings in ink consumption.
