ABSTRACT:
Process for producing a silicone coated embossing roll for continuously embossing the surface of thermoplastic film. A laser beam is used to cut into the smooth silicone rubber surface of the roll, a pattern or design which replicates a negative of a leather grain, for example. The intensity of the laser beam and its movement is controlled by a signal generated by scanning the original leather grain. This process permits a simple and inexpensive way to produce an embossed structure in the silicone surface of an embossing roll, even when the structure to be repeated is extremely fine. No tedious manual steps are necessary to achieve the most natural possible reproduction in embossing.
