Apparatus is provided for use in printing systems wherein regions of rupturable capsule layer are ruptured to release dye that prints an image on an image-receiving sheet. An optical valve member is positioned between a light source and an imaging sheet which has the layer of capsules on its surface. An image pattern formed on a ferroelectric ceramic plate of the optical valve member by the irradiation of an electron beam together with an ultraviolet light in accordance with each color separation signal is projected onto the imaging sheet. The imaging sheet projected with the image is positioned so that the layer of capsules lies between the imaging sheet and the image-receiving sheet. A pressure roller applies pressure against the imaging sheet and the image-receiving sheet to rupture the capsules between them to thereby transfer the dye to the image-receiving sheet.

Capsule rupture printing system

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.
