Abstract

A printing cylinder or a sleeve is coated with a continuous photosensitive recording layer by applying a first jointless stratum of a photosensitive recording layer to the printing cylinder or the sleeve, and uniformly preexposing this first stratum to actinic light and thereafter applying one or more further jointless strata of the photosensitive recording layer to this preexposed first stratum.
