Abstract
Apparatus is provided for use in color printing systems wherein an image is projected by a plural monochrome pictures corresponding to the pictures separated into three primary colors onto an imaging sheet which contains a dye and a photosensitive composition encapsulated in a layer of pressure rupturable capsules. The imaging sheet projected the image is positioned so the layer of capsules lies between the imaging sheet and an image-receiving sheet. A pressure roller applies pressure against the imaging sheet and the image-receiving sheet to rupture the capsules between them and thereby transfer the dye to the image-receiving sheet.
