Abstract
A substantially tubular interchangeable sleeve is adapted for applying a printing or coating liquid to a substrate material or offset roller. The sleeve has a multi-layer construction primarily consisting of a first outer layer of a dimensionally stable substantially fluid-impregnable solid material, such as aluminum or steel, around the exterior surface of which is affixed or applied a print or coating liquid receiving plate or layer. The sleeve further comprises one or more further interior layers of relatively less dimensionally stable, compressible, usually fibrous materials disposed inwardly of the interior surface of the first layer which, under air pressure, can be compressed so as to enlarge the inner dimensions of the sleeve so that it can be slid over a suitable bridge mandrel. The sleeve further comprises at least one end ring of a dimensionally stable substantially fluid-impregnable solid material.
