摘要： A method for determining local defocus distance in a scanned image of a non-planar original object is provided comprising scanning at least a portion of the non-planar original object to produce first scanned image data at a first focal plane and scanning same the at least a portion of the non-planar original object to produce at least second scanned image data at a second focal plane. The first scanned image data is different from the second scanned image data wherein a distance between the first focal plane and the second focal plane is a predetermined quantity. The method further comprises estimating an out-of-focus distance of the object from the first and the second scanned image data.

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 to expand the range of image densities over which a desired glossmark image will bear an effect.

摘要： A method and apparatus for producing high quality toner images in an electrostatic printing machine. The method using the apparatus includes (a) (a) forming an initial developed toner image on a photoreceptor using a first toner image forming assembly including a charging device for uniformly charging the photoreceptor, and a development assembly, including charged toner solids having a single polarity, for image-wise applying a layer of the toner solids to the latent image to form an initial developed toner image; (b) refining the initial developed toner image using an air breakdown charging assembly, including a relatively large magnitude voltage biasing source and a nip forming roll coupled thereto, for image-wise recharging of the single polarity toner solids layer forming the initial developed toner image. The air breakdown charging assembly induces an air breakdown electrical discharge wherein free mobile ions are introduced into a vicinity of the initial developed toner image, and the latent image underlying the initial developed toner image cooperates with the large magnitude voltage biasing source to cause free mobile ions to flow to toner solids of the initial developed toner image in an image-wise manner, thereby image-wise recharging toner solids of the initial developed toner image such that image area toner solids then have a first polarity, and background toner solids then have a second and relatively opposite polarity; and (c) separating the image area toner solids from the background area toner solids, so as to refine the initial developed toner image, thereby resulting in a high resolution, high quality refined final toner image consisting of the image area toner solids having highly clean background areas.

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： The present invention relates to creating differential gloss images in clear toner by the manipulation of halftones employed prior to the depositing of the clear toner layer upon a substrate. By selectively applying halftones with anisotropic structure characteristics which are significantly different in orientation although remaining identical in density, a differential gloss image may be superimposed within even clear toner as applied to paper. Further, this technique may be used to enhance color toner Glossmark images across the low and high density areas of application where the differential gloss effect would otherwise be weak.

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.
