<p>PURPOSE:To eliminate a need of generation of cut masks and repeated exposure and to improve the production efficiency of a negative film by projecting a laser beam to selectively expose only required parts of a color separation film on an unexposed film. CONSTITUTION:The laser beam is controlled based on mask data inputted from an image information input part and is projected to only required parts of a color separation film 1 put on an unexposed film 8. Consequently, unnecessary parts of the color separation film 1 are not exposed on the unexposed film 8 without cut masks. Thus, cut masks are unnecessary, and much time and the material cost required for generation of cut masks are eliminated to not only improve the productivity but also reduce the material cost.</p> |
