摘要： A method for reduction of differential gloss as found in hardcopy image prints. The method comprises selecting a first halftone having a high apparent gloss characteristic and a second halftone having a low apparent gloss characteristic while retaining an identical matching density characteristic to the first selected halftone. a A determination is then made of which areas of the halftone image correspond to potentially high gloss and low gloss regions under normal printing conditions. The first halftone is applied to those portions of the halftone image determined as corresponding to potentially low gloss regions, and the second halftone is applied to those portions of the halftone image determined as corresponding to potentially high gloss regions of the halftone image.

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 defining material, such as a dampening fluid. The image defining material forms a negative pattern of the image to be printed. This negative image is then transferred to the reimageable surface. The negative image is then developed with ink. The inked image may be transferred to a substrate.

摘要： A method for reduction of differential gloss as found in halftone image hardcopy prints. The method comprises selecting either a single halftone or employing two halftones: a first halftone having a high apparent gloss characteristic; and a second halftone having a low apparent gloss characteristic. A determination is then made of which areas of the halftone image correspond to potentially high gloss and low gloss regions under normal printing conditions. An overlay of clear toner is applied to the hardcopy print of the halftone image. In one approach a single halftone is employed to control the physical area coverage of the applied clear toner layer so as to adjust the local gloss across for the determined regions and thereby balance the evenness of gloss across the entire hardcopy print of the halftone image. Greater physical area coverage is provided as controlled by the single halftone in low gloss regions, and corresponding less physical area coverage is provided in the low gloss regions. In a further approach two halftones are employed. The first halftone is directed to those portions of the overlaid clear toner determined as corresponding to potentially low gloss regions of the halftone image, and the second halftone is directed to those portions of the clear toner layer determined as overlaying potentially high gloss regions of the halftone image.

摘要： The present invention relates to expanding the range of image densities over which the manipulation of differential gloss as may be inherent in halftoned images may be achieved. By selectively applying halftones with anisotropic structure characteristics which are significantly different in orientation while remaining identical in density, a gloss image may be superimposed within an image without the need for special toners or paper. This technique may be enhanced across low and high density areas by application of clear toner. Further, in color systems, light color toner may be applied to low density image areas and dark under-color applied in high density image areas, to expand the range of image densities over which a desired glossmark image will bear an effect.
