ABSTRACT:
A latent image on an exposed and developed sheet S of photosensitive material coated with microcapsules containing a color forming substance is transferred to a superposed image receiving sheet C by applying pressure to rupture some of the microcapsules. The applied pressure is selectively varied between at least two levels to attendantly control the color density of the transferred image.
