The printing machine and method include a movable photoreceptor having a photoconductive surface for supporting electrostatic charge; a first charging device for selectively charging only scattered portions of the surface of the photoreceptor; a liquid developer material supply and application apparatus for applying a coat of charged toner solids having a single polarity onto each charged selected scattered portion, thereby forming an image area patch of toner; an exposure device for image-wise exposing each charged selected scattered portion to form a first latent image therein; and a contact electrostatic printing (CEP) assembly including a conductive (CEP) roll and a bias source coupled thereto, for applying compressive and tensile forces to the image area centered patches of toner moving through an image processing nip formed by the photoconductive surface of the photoreceptor and the conductive CEP roll, wherein the bias source cooperates with a charge pattern of the image area centered patches of toner to generate image-wise electric fields within the image processing nip, and the image-wise electric fields together with the compressive and tensile forces, enable easy separation of background area toner solids from image area toner solids of the image area centered patches of toner, and onto the CEP roll; thereby resulting in an efficiently produced, quality toner image with significantly reduced non-development marking material generated and requiring removal.

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 and apparatus for producing high quality liquid toner images in an electrostatic printing machine. The method using the apparatus includes selectively coat a photoreceptor only in selected image area centered portion of the photoreceptor surface thereby forming an image area centered patch of toner with developing material; image-wise exposing each such portion; patch of toner. The method using the apparatus next includes forming a final toner image from each image area centered patch of toner using an air breakdown charge development (ABCD) assembly. The ABCD assembly includes a relatively large magnitude voltage biasing source, and a nip forming roll coupled thereto and forming a toner solids recharging nip with the photoreceptor, for image-wise recharging of the single polarity toner solids coating each image area centered patch of toner, by inducing an air breakdown electrical discharge in which free mobile ions are introduced into the vicinity of each image area centered patch of toner. The latent image underlying each image area centered patch of toner cooperates with the large magnitude voltage biasing source to cause free mobile ions to flow to the toner solids of each image area centered patch of toner in an image-wise manner corresponding to the underlying latent image. This, in turn, leads to image-wise recharging of the toner solids of each image area centered patch of toner in which toner solids in image areas of each patch then have a first polarity, and toner solids in background areas thereof then have a second and relatively opposite polarity. The method of the present invention then includes separating the image area toner solids of each patch of toner from the background area toner solids thereof, thereby resulting in an efficiently produced, quality toner image with significantly reduced non-development marking material generated and requiring removal.

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.
