Dampening fluid deposition by condensation in a digital lithographic system
Abstract:
A system and corresponding methods are disclosed for depositing of a layer of dampening fluid to a reimageable surface of an imaging member in a variable data lithography system by way of condensation. Dampening fluid in an airborne state is introduced proximate the reimageable surface in a condensation region. Conditions in the condensation region are such that the airborne dampening fluid preferentially condenses on the reimageable surface in a precisely controlled quantity, to thereby form a precisely controlled layer of dampening fluid of desired thickness over the reimageable surface. Among other advantages, improved print quality is obtained.
