Claims12
A liquid electro-photographic (LEP) printer, comprising a structure having a repel coating disposed on a portion of the surface of the structure that contacts an ink formulation, wherein the repel coating is a highly fluorinated compound, wherein the ink formulation is a non-fluorinated ink formulation, and wherein the ink formulation does not substantially accumulate on the surface of the structure and wherein the highly fluorinated compound is selected from the group consisting of a perfluoropolyether (PFPE), a fluorinated epoxy, a fluorinated urethane, a fluorinated acrylic, and a combination thereof.
A liquid electro-photographic (LEP) printer, comprising a structure having a release coating disposed on a portion of the surface of the structure that contacts an ink formulation, wherein the release coating is a fluorinated polyurethane, and wherein the ink formulation does not substantially accumulate on the surface of the structure.
