    摘要： Negative-Working Lithographic Printing Plate Precursors can be provided with desired contrast coloration after imaging using a coloring fluid that includes a water-insoluble colorant that is soluble in a water-insoluble fatty alcohol. The coloring fluid provides an optical density change in the exposed regions of at least OD2 that is greater than the original optical density of those regions, OD1. The coloring fluid can be applied immediately after imaging and before processing, or it can be applied as part of the developer or processing solution, or it can be applied after processing. The coloring fluid can also be applied to imaged precursors that are designed for either off-press or on-press development.

    摘要： A method is disclosed in the context of a system comprises an electrophotographic subsystem, a transfer subsystem, an imaging member, and an inking subsystem. The electrophotographic subsystem comprises a photoreceptor, a charging subsystem, an exposure subsystem, and a development subsystem. In operation, the photoreceptor is charged areawise. An exposure pattern is formed by the exposure subsystem on the surface of the charged photoreceptor to thereby write a latent charge image onto the photoreceptor surface. The image is developed with an image definition material, such as a dampening fluid. The image definition material forms a positive pattern of the image to be printed. The image pattern is then transferred to the reimageable surface. The transferred pattern is then developed by selectively applying an ink over regions of image definition material. The inked image may be transferred to a substrate.

    摘要： A variable lithographic inking system includes a chamber blade system configured to supply ink to an anilox member of an inking system. The inking system includes a soft ink transfer roll and a hard form roll. Ink is transferred from the anilox roll to the form roll by way of the transfer roll, and from the form roll to a reimageable surface layer of an imaging member of a variable data lithographic system. An ink layer free of ink history is uniformly applied onto a surface of the form roll, and subsequently transferred to the reimageable surface layer while avoiding or substantially eliminating image ghosting related to inking non-uniformities.
