Abstract
A device for forming a flexographic printing plate is disclosed. A preformed, imagewise irradiated sheet of film is heat treated by the device of the present invention to remove unwanted portions of a top layer, leaving radiation hardened relief images on the plate. The device has a heating means for supplying heat to said film, a first delivery means for delivering a sheet of absorbent material to a surface of the film, a second delivery means for supplying film to the heating means, pressure means for causing liquified material to be absorbed onto an absorbent material, and a separation means for separating the absorbent material from the film.
