摘要： A shallow relief non-bottoming printing plate is disclosed having a polymerized layer of less than about 0.020 inch and which includes a plurality of dispersed particles sufficient to create small protuberances in non-image or background areas to prevent bottoming. Photopolymerizable elements, as well as processing techniques, are also disclosed for making such printing plates.

摘要： An apparatus for processing photopolymer plates includes an exposure unit, a washing unit, and a drying unit. The plate, which has a water-developable photopolymer surface, is continuously conveyed through each unit so that the functions therein performed, are done automatically. More particularly, exposure is accomplished by bringing a negative photographic image into alignment with the water-developable photopolymer plate, and then passing light through the negative and onto portions of the plate. Unexposed areas of the plate are then washed away in the washing unit, thus producing a relief surface necessary for letter-press printing. Finally, the photopolymer plate is conveyed to the drying unit where drying and postcuring take place.

摘要： Letterpress and offset photopolymer printing plates are disclosed having relatively thin water developable photopolymer layers, which, after being developed, have ink-repulsive, non-image areas. Adhesive layers are provided in the disclosed printing plates that are interposed between an ink-repulsive coating contained in the printing plate substrate and the water-developable photopolymer, and provide a balance between satisfactory adhesive and ink-repulsive properties in the resulting plate.
