Fairchild Experimental Electronic Color Correction Investigation.

Fairchild's investigation of electronic color correction during the last several years is reviewed. The results show the feasibility of direct halftone screening of corrected color separations from transparencies. The masking corrections are linear; certain other corrections, derived from an inversion of Neugebauer's equations, do not seem completely necessary. The simplicity and value of the corrections are dependent on the method of making a contrast adjustment. The primary signals fed to the masking computer represent a gamma of about one-half the gamma of a neutral scale while the ratios of the primary signals are preserved.
