Abstract
A method for optimizing colored images emitted by a color printer on the non-white surfaces of substrates and for optimizing the amounts of printing ink used, wherein an image motif is processed by a computer-assisted image processing system in order to form a master copy which is ready for output. The method determines, for each pixel, whether and with what color density, a white underprint can be applied to a corresponding pixel, using an algorithm based on overall color density S . The surface of the substrate is thus only underprinted with white on the pixels of the master copy where the overall color density is lacking or low.
