Abstract
A method for preparing a printing plate is disclosed. The method comprises contacting a heat sensitive medium, comprising a support and provided thereon a heat transfer layer containing a colorant, a heat fusible substance and a photo-curable composition, with a recording material having a hydrophilic recording surface through the heat transfer layer, applying heat in an image pattern to the contacted materials to transfer the image onto the recording material, and exposing the transferred image to actinic radiation to cure the transferred image.
