Abstract
For coating printing cylinders or sleeves with a seamless, smooth photosensitive layer, two or more strata of a thin, prefabricated, essentially solvent-free, unsupported, thermoplastically processible, solid, photosensitive layer are applied to the printing cylinder or the sleeve, without bubbles and with displacement of the air between the individual strata, and the total photosensitive layer material is then heated under pressure and with joining or fusion of the individual strata to form a single, continuous photosensitive layer, and the surface of the resulting photosensitive layer is aftertreated to shape it exactly to size and is smoothed, with formation of an exactly cylindrical shape.
