Abstract
Color separation image signals (Y, M, C, K) are converted into halftone dot image signals (Y.sub.d, M.sub.d, C.sub.d, K.sub.d) by a halftone block circuit (29). Red, green, blue and white beams are obtained from red, green and blue light sources (31R, 31G, 31B) or from a single white light source. These beams are modulated by acousto-optical modulators (32R, 32G, 32B, 35) responsive to the halftone dot image signals (Y.sub.d, M.sub.d, C.sub.d, K.sub.d) and thereafter converged onto a color photosensitive material (23), to produce a halftone dot color image on the color photosensitive material (23).
