A reimageable layer of an imaging member is provided with a dampening fluid layer. The reimageable layer has specific properties such as composition, surface profile, and so on so as to be well suited for receipt and carrying the dampening fluid layer. An optical patterning subsystem such as a scanned modulated laser patterns the dampening fluid layer. Ink having a first set of properties such as color, composition, etc., is applied at an inking subsystem such that it selectively resides in voids formed by the patterning subsystem in the dampening fluid layer to thereby form an inked latent image. The inked latent image is then transferred to a substrate, and the reimageable surface cleaned. The process is repeated for a second ink having properties different than the first. Each ink image may successively be applied to the substrate, or a composite image may be formed then applied to the substrate.

A trapping determining unit determines, for each color plane of an N-valued image, on the basis of the calculated characteristic values, whether the pixel of interest is to be subjected to trapping processing. A pixel value calculator sets, for each color plane, a position of a reference pixel in a reference area, and calculates a pixel value for changing the pixel value of the pixel of interest on the basis of a pixel value of each color plane at the position of the reference pixel. A pixel-of-interest value changing unit changes the pixel value of the pixel of interest into the calculated pixel value when the trapping determining unit determines that the pixel of interest is to be subjected to trapping processing.

Автор: Chu-heng Liu, Peter Knausdorf
Принадлежит: Xerox Corp

A system and corresponding methods are disclosed for controlling the thickness of a layer of dampening fluid applied to a reimageable surface of an imaging member in a variable data lithography system. Following deposition of the dampening fluid layer, a gas is passed over a region of the fluid layer prior to pattern forming. The gas causes a controlled amount of the dampening fluid layer to evaporate such that the remaining layer is of a desired and controlled thickness. Among other advantages, improved print quality is obtained.
