MULTILAYER GRAPHIC ARTS ROTATING SLEEVE

摘要

A graphic arts sleeve includes a cylindrical plate presenting an outermost sleeve surface operable to engage and thereby texture, print, and/or hot foil stamp on a substrate. The cylindrical plate presents an innermost support surface opposite the outermost sleeve surface and operable to engage a mandrel. The cylindrical plate includes an intermediate carrier layer and an overlying engravable layer cladded to and supported by the carrier layer. The cylindrical plate further includes an underlying expansion layer cladded to the carrier layer. The expansion layer has a greater coefficient of thermal expansion than the carrier layer, with heating of at least the expansion layer causing diametrical expansion of the innermost support surface to facilitate mounting or removal of the cylindrical plate relative to the mandrel.
