Claim:
1. A variable lithography system imaging member, the imaging member comprising a reimageable surface layer surrounding and in contact with a substrate, the reimageable surface layer being the outermost layer of the imaging member and having a micro-roughened surface configured to receive and transfer ink to a receiving substrate and to retain a dampening fluid on the micro-roughened surface, the dampening fluid being different than the surface layer, the reimageable surface layer configured to remain with the substrate during rotation thereof within the variable lithography system and during ink transfer to the receiving substrate, wherein the reimageable surface layer comprises a fluoroelastomer-fluorosilicone composite formed from a reaction of a fluoroelastomer, an oxyaminosilane, and a fluorinated oxysilane-terminated compound, wherein: a weight ratio of the fluoroelastomer to the oxyaminosilane is in a range of between 50:40 and 85:5; a mole ratio of the oxyaminosilane to the fluorinated oxysilane-terminated compound is in a range between 2:1 and 1:10; and the weight ratio and the mole ratio are maintained in a final surface layer of the imaging member.
