Abstract
Apparatus is provided for use in printing systems wherein regions of rupturable subminiature capsules of a layer of capsules are ruptured to release dye that prints an image on an image-receiving sheet. A thin backing sheet is positioned so the layer of capsules lies between the backing sheet and the image-receiving sheet. A rotating brush brushes against a rear face of the backing sheet which is opposite the capsules, to apply pressure against multiple small independent areas of the backing sheet, to deflect each small area of the backing sheet towards the image-receiving sheet to rupture the capsules between them and thereby transfer the dye to the image-receiving sheet.
