Methods for ink-based digital printing using imaging member surface conditioning fluid

摘要

An ink-based digital printing method includes applying conditioning fluid to an imaging member surface wherein the fluid is absorbed by imaging member surface, which includes VITON. Dampening fluid is subsequently applied to the imaging member surface for development by a laser imaging system to form a latent image. Ink is applied to the developed latent image on the imaging member surface to form an ink image that is transferred to paper to form a print that is free of tiger stripe image quality defects.

1. A method for ink-based digital printing system, comprising:
applying a conditioning fluid to an imaging member surface whereby the imaging member surface absorbs the conditioning fluid, the conditioning fluid comprising a hydrofluoroether liquid, the imaging member surface comprising a fluoropolymer elastomer; applying a uniform layer of dampening fluid to the imaging member surface, the surface being impregnated with the conditioning fluid; and inking the imaging member surface after applying the conditioning fluid.
