Abstract: The advantages of a planographic dye transfer matrix over a conventional relief matrix include improved image sharpness and reduced image graininess in the resulting print, and greater flexibility in construction of the raw stock and its use by avoiding the requirement for exposure through the film base. A plano-graphic matrix may be prepared by reversal processing of the stock after exposure, followed by toning the reversal silver image. The dye resist formed by copper toning of this image is believed to be a semipermeable membrane of copper ferrocyanide which forms at the interface between the silver-gelatin “non-image” and the gelatin “image” or at the surface of the film. A mechanism is proposed for the formation of this membrane and experimental evidence in support of this mechanism is presented. The importance of such factors as Cu/Fe ratio, pH, properties of the stabilizing ligand, and nature of the anion in the toning solution is discussed.
