    摘要: A method for producing a press-ready lithographic printing plate which comprises:(A) providing an uncoated lithographic substrate;(B) coating a photosensitive layer on one side of the lithographic substrate;(C) providing a flexible substrate;(D) coating an adhesive layer directly on the flexible substrate;(E) laminating the coated lithographic substrate to the coated flexible substrate;(F) imagewise exposing the laminated element of (E) to radiation to which the photosensitive layer is sensitive; and(G) peeling off the flexible substrate along with the nonimage areas of the photosensitive layer, leaving the press-ready image areas of the colored photosensitive layer and the adhesive layer on the lithographic substrate.

    摘要: A process for producing a color image on color proofing film which comprises:(i) providing digital data representative of the shape and color of an original image;(ii) inputting the digital data into a computer;(iii) providing a color printer which is in communication with and controlled by the computer;(iv) providing the printer with a precoated photosensitive color proofing film, a thermal wax and means for transferring the wax to the color proofing film;(v) melting the thermal wax, in response to the digital data, in a manner which provides a pattern corresponding to the shape of the original image, the pattern providing a temporary wax optical mask;(vi) exposing the photosensitive layer of the color proofing film, through the thermal wax optical mask, to actinic radiation, the wax on the color proofing film absorbing the actinic radiation, whereby a photoreaction occurs in the exposed areas of the photosensitive layer of the color proofing film; and(vii) developing the color proofing film to provide a color image corresponding to the original image.
