  • Method for the printed reproduction of continuous-tone polychrome originals
    Patent number: 5095819
    Abstract: Continuous-tone polychrome subjects (O) are reproduced by ink printing on a substrate. The reproduction is achieved by the synthesis of three chromatic components, one of which corresponds to the color of the substrate and the other two of which correspond to the colored inks used for the printing. In one variant of the method, one of the colored inks is replaced by a black ink, printed with a plate made from the achromatic component of the subject.
