ABSTRACT:
Gravure printing plates which are highly abrasion-resistant and scratch-resistant can be produced rapidly and simply from a photosensitive recording material by exposing the latter through a photographic positive, washing out the unexposed areas and drying the resulting gravure printing plate, if the photosensitive recording material employed, which comprises a photopolymerizable and/or photocrosslinkable layer (L) applied to a dimensionally stable base, contains finely divided, hard, abrasive particles in the layer (L), the surface of this layer, which subsequently constitutes the surface of the printing plate, has a peak-to-valley height of <2 .mu.m, and the materials of this layer are chosen so that, after exposure and development, it has a Vickers hardness of not less than 10 N/mm.sup.2, measured under load.
