Abstract
A method of production of photopolymer printing plates particularly characterized in the transfer procedure. In the method, an electrostatic latent image of original material is produced on a photoconductive medium, the image is developed by application of toner particles, and the toner image is transferred onto photopolymer printing plates having photosensitive resin layer or containing polymerizable monomer through linear pressure of line contact. The toner image thus transferred is then exposed to light without being fixed, plate portions defined by the toner image being subsequently removed together with the toner particles.
