Abstract
An imaging member surface contains a swellable elastomer doped with a release oil. This aids in complete transfer of ink to a receiving substrate when a thin film of release oil forms upon the surface during application of pressure at the nip.
Claims11
A offset lithographic imaging member comprising a reimageable surface layer surrounding and in contact with a substrate, and a liquid boundary layer, the reimageable surface layer having a micro-roughened surface configured to receive, carry, and transfer ink to a receiving substrate and to retain the liquid boundary layer on the micro-roughened surface, the reimageable surface layer cured and comprising a swellable fluorosilicone elastomer having a release oil therein, the fluorosilicone including a polyorganosiloxane having a backbone formed from silicon and oxygen atoms, and sidechains containing carbon, hydrogen, and fluorine atoms, the liquid boundary layer on the micro-roughened surface of the reimageable surface layer including a portion of the release oil, wherein the surface layer is configured to transfer the portion of the release oil to the liquid boundary layer.
