ABSTRACT:
Apparatus and method for producing color hardcopy from computer or video generated electronic information and utilizing a film with a repeating color stripe pattern on one side and an unexposed silver halide layer on the other side. A laser beam of a single monochromatic frequency scans across the unexposed silver halide layer from the side opposite the color stripes, the beam being smaller than an individual color stripe and being modulated in intensity to provide a variable strength latent image in the silver halide corresponding to red, blue and green intensity components of the video image so that the resulting film can be illuminated from either side to be viewed in color after processing.
