    摘要： The present invention is directed to a method and a system for forming a relief image on a photosensitive printing element. The system comprises an enclosure housing a conveyor and a heatable roller. The photosensitive printing element is positioned on a continuous loop of the conveyor and the heatable roller is urged towards the photosensitive printing element on the conveyor. An absorbent material is conducted over the heatable roller and is used to absorb at least a portion of the liquefied or softened material from the photosensitive printing element when the heatable roller is heated. The system also comprises ventilation means operatively connected to the enclosure for treating and recycling air containing contaminants that are released into the enclosure as the portion of the photosensitive material is heated and then softens. The ventilation means typically include a particulate filter and a bed of adsorbent material. The treated air may then be returned to the enclosure.

    摘要： The method of manufacturing an electrotype printing plate comprising the steps of electroforming a shell having raised characters on its front face and corresponding recesses on its backface, fusing a nylon coating to the back of the plate to fill the recesses, providing a metallic backing plate having a predetermined curvature, applying thermosetting adhesive to one of the backing plate or the coating. The plate is applied to vacuum apparatus comprising an apertured saddle member which includes heating means and diaphragm means constructed and arranged to cover the plate. The plate is heated and a vacuum is simultaneously drawn through the apertures wherein the diaphragm firmly presses the plate to the backing member and the adhesive is cured.
