Abstract: The present invention is a laser engravable embossing roll exhibiting improved wear characteristics and life span through the use of an epoxy resin based material. Specifically, the embossing roll according to the present invention can be produced using standard laser engraving techniques that have heretofore been applied to rubbers. Rubber rolls, while produced significantly faster than engraved steel rolls, have the disadvantage of poor life span due to wear. The epoxy based resin rolls of the present invention overcome these disadvantages by being quickly and easily produced using laser engraving but exhibiting significantly improved wear characteristics.
