Method of making mating male embossing rolls
Abstract
A method for manufacture of a male embossing roll which registers exactly with another male embossing roll, which comprises forming in the second roll a mating female pattern, filling the female pattern depressions with resist, and then etching, thereby to produce a male design corresponding to the female design. The filling of the preliminarily formed female design by a resist comprising chrome plating is a preferred embodiment, the entire roll being chrome plated after the formation of the female design, the chrome plate then being removed from the surface of the roll except in those areas corresponding to the depressions in the female pattern previously formed therein.
