A THEORETICAL INVESTIGATION OF COLOR CORRECTION MASKING FOR THE GRAPHIC ARTS A Research Thesis Presented to the Faculty of the School of Photographic Arts and Sciences Rochester Institute of Technology In Partial Fulfillment of the Requirements for the Degree Master of Science by Clarence R. Gutteridge Jr. June 1968 ABSTRACT 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 . Spectrophoto metric curves were used as originals and the needed ink amounts to reproduce these colors were specified by a set of transformation equations . The rela tionship obtained by regression analysis did not completely agree with con ventional masking requirements . TThe results of this investigation are com pared with the negative photographic mask technique to investigate the inadequacies of the photographic process to give adequate masking .
