The theoretical functional relationship between mask density and original red, green, and blue densities has been described for a photomechanical reproduction system. A computational model simulating the reproduction system was derived and programmed on a digital computer. Spectrophotometric curves were used as originals and the needed ink amounts to reproduce these colors were specified by a set of transformation equations. The relationship obtained by regression analysis did not completely agree with conventional masking requirements. The results of this investigation are compared with the negative photographic mask technique to investigate the inadequacies of the photographic process to give adequate masking.
