Method for Direct Application of Dampening Fluid for a Variable Data Lithographic Apparatus
摘要:
A system and corresponding methods are disclosed for applying a dampening fluid to a reimageable surface of an imaging member in a variable data lithography system, without a form roller. In one embodiment, the system includes subsystems for converting a dampening fluid from a liquid phase to a dispersed fluid phase, and for directing flow of a dispersed fluid comprising the dampening fluid in dispersed fluid phase to the reimageable surface. The dampening fluid reverts to the liquid phase directly on the reimageable surface. In another embodiment a continuous ribbon of dampening fluid may be applied directly to the reimageable surface. This embodiment includes a body structure having a port for delivering dampening fluid in a continuous fluid ribbon directly to the reimageable surface, and a mechanism, associated with the body structure, for stripping an entrained air layer over the reimageable surface when the reimageable surface is in motion.
