Abstract
An apparatus is provided for use in color printing systems wherein an image is projected by a plurality of monochrome pictures corresponding to the pictures separated into three primary colors onto an imaging sheet which contains in layers pressure rupturable capsules, each encapsulating a dye and a photosensitive composition. The plural monochrome pictures are made by a laser scanner unit on the surface of a photosensitive drum according to image information and are transferred from the surface of the photosensitive drum to a transparent film. The transparent film is moved between a light source unit and a projection lens unit to project the plural monochrome pictures onto the imaging sheet.
