Abstract:
An intermediate roller positioned between a fountain solution vapor supply and an imaging member decouples fountain solution vapor deposition from the surface of the imaging member. The intermediate roller may be temperature controlled. A uniform layer of fountain solution condenses onto the surface of the temperature controlled intermediate roller regardless of the imaging blanket temperature. The fountain solution condensate layer deposited onto the intermediate roller splits and deposits a thin uniform layer of fountain solution liquid onto the imaging member surface. This liquid layer split may be independent of the temperature of the imaging member surface, resulting in a uniform layer of fountain solution on the imaging blanket for better imaging quality. Remotely locating the vaporizing chamber away from the imaging member prevents undesired heat transfer from a hot vaporizing chamber/baffle to the imaging member surface.
