摘要： A method of printing a job having a type using an electrophotographic (EP) printer includes receiving the job and its type. A processor is used to automatically select a first or a second job mode based on the job type; the first job mode indicates aggressive gray component replacement (aGCR) is used but not clear toner, and the second job mode indicates clear toner is used but not aGCR. The data of the job are processed using the processor according to the selected job mode to provide six separations corresponding to respective colorants. Toner corresponding to the six separations is then applied to the receiver using at least one EP printing module in the EP printer to produce a print image of the job.

摘要： An image processing method and apparatus for generating a gray level rendered pixel value that has been subjected to a halftoning process. In the method and apparatus a gray level pixel value of the pixel to be rendered by the halftoning process is provided as one input to a lookup table. A coordinate value that is determined from a pixel location in the image of the pixel to be rendered by the halftoning process is also provided as a second input to the lookup table. The first and second inputs represent an address in the lookup table of a rendered halftone value for halftone rendering of the pixel having the input gray value and the pixel location in the image.

摘要： A system and method for selective color-correction when applying three-dimensional texture to a printed substrate hinges either on a metric that is elicited from the image, or as determined by an operator. The metric may be associated with the human visual acuity curve for textural information. Other textural metrics may also be used.

摘要： A method and apparatus of reproducing an image in which an original image is scanned to produce a digital representation of the original image as a plurality of original pixels regularly located within the original image and each having a grey level value. Replacement pixels randomly located within boundaries of the original image are generated. The grey level values of the original pixels are interpolated and an interpolated grey level value is assigned to each of the replacement pixels. A reproduction of the original image is generated using only the replacement pixels and their assigned interpolated grey level values.

摘要： A method and apparatus for reproducing an original image includes a scanner or other image source for generating digitized raw image data for each pixel of an image. For each pixel, the raw image data is transformed into a rendering gray level value by comparing the raw image data value with threshold values from a threshold mask set. There are various threshold mask sets that may be used in accordance with signals related to a toner particle size.

摘要： A method and apparatus for modifying a digitized image in which the digitized image is received as input pixel values for a plurality of pixels, first selects an unprocessed one of the pixels to be a current pixel. The current pixel is modified by adding a total error value and a screen frequency component to the input pixel value of the current pixel to produce a modified current pixel value. The modified current pixel value is thresholded to produce an output pixel value for the current pixel, which becomes a processed pixel. The output pixel value is then mapped into an image range, and a total error incurred for the processed pixel caused by the mapping is determined. The total error incurred is distributed to at least one of the other of the plurality of pixels that is an unprocessed pixel. The procedure is repeated for each pixel in the plurality of pixels to provide a modified digitized image.

摘要： An electrographic printing system for forming a tactile printed image on a receiver medium, comprising an image processing path, one or more printing modules and a fixing subsystem. The image processing path provides a sequence of image patterns including a plurality of annular shapes having associated inner and outer sizes, the inner and outer sizes of the annular shapes varying in a monotonic sequence. The printing modules are controlled to form a sequence of toner particle images corresponding to the sequence of image patterns, and to sequentially transfer the sequence of toner particle images in register onto the receiver medium such that the annular shapes in the toner particle images overlap to form a tactile image feature having a hollow core. The fixing subsystem is used to permanently attach the transferred toner particle images to the receiver medium.

摘要： Automatically determining the cost of a printed job on a digital printing press before the job is run. A job control component in the digital front end of the printing press collects and stores the processing information from the job processing components from prior runs. A job-reporting component displays the stored and estimated processing information and automatically computes and displays the estimated cost of the job. The method includes determining a future toner cost using a toner cost, a future press usage cost, and a substrate cost based on historical toner consumption and then rasterizing the job to determine the total job cost.
