ABSTRACT:
According to the present invention there is provided a method for making driographic printing plates comprising the image-wise exposure of a heat-sensitive recording material comprising on an ink-accepting support an image-forming layer containing nydrofobic thermoplastic polymer particles and a compound capable of converting light into heat, said compound being present in said image-forming layer or a layer adjacent thereto and a cured ink-repellant surface layer. After the exposure the printing plate is developed by wiping it with water or an aqueous solution before or after mounting it on the print cylinder of a printing press.
