Abstract
Density signals (S.sub.y, S.sub.M, S.sub.C, S.sub.K) representing yellow, magenta, cyan and black densities on an original color image are inputted and are subject to color computations in a color computation circuit (202). The corrected density signals (S.sub.Y1, S.sub.M1, S.sub.C1 S.sub.K1) are converted into halftone dot singals (S.sub.DY, S.sub.DM, S.sub.DC, S.sub.DK), respectively. The halftone dot signal for black is combined with the other three halftone dot signals individually in combining circuits (204.sub.y, 204.sub.m, 204.sub.c) and are employed for recording a color proof image on a color photosensitive film (PF).
