  • Method and apparatus for obtaining lithographic plate
    Patent number: 6096473
    Abstract: A method for making a lithographic printing plate according to the silver salt diffusion transfer process image-wise exposes an imaging element with a high intensity short time scanning exposure. The imaging element comprises on a support in the order given a silver halide emulsion layer and a layer containing physical development nuclei. A thus obtained image-wise exposed imaging element is subsequently developed in the presence of a developing agent and silver halide solvent. The image-wise exposure is focused substantially within the silver halide emulsion layer of the imaging element. The present invention further provides an apparatus for carrying out the above method.
