摘要： A system for visualizing a print job includes a print job simulator which applies a print job model to print job image data to generate an image which simulates a rendered image of the print job if the print job were to be printed on a specific marking device. The system also includes a display in communication with the print job simulator for displaying the simulation image. The modified image data displayed on the display enables a customer to see a defect in the print job which would appear if the print job were to be rendered on the specific marking device. The print job model may be derived, at least in part, from information derived from the marking device, such as information derived from image data acquired by scanning a test image which has been rendered by the marking device.

摘要： What is disclosed is a system and method for generating a destination profile LUT. In a manner more fully described herein, a high resolution LUT (e.g., 100-cube LUT) is received. Regions of high curvature of the gamut of an image output device are identified. A non-parametric dynamic optimization node selection method is utilized to select a subset of nodes from the high resolution profile LUT which captures these nonlinearities. Down-sampling the high resolution LUT produces a low resolution LUT. The low resolution LUT is up-sampled to a size of the high resolution LUT to obtain a reconstructed LUT. An error is then calculated between the reconstructed LUT and high resolution LUT. The process of node selection is iteratively repeated until all the subsets of nodes are considered. A destination profile LUT is then generated from the subset of nodes with the least error.

摘要： The predicted tone response curve for each color channel and halftone is predicted using a binary printer model and stored, wherein the “predicted tone response curve” provides a model based approximation of the actual response for the printer for each addressable pixel location in the spatial range. Also stored is an “average predicted tone response” by averaging the “predicted tone response curve” over the spatial range of the printer. With the “true average” tone response curve, the “predicted tone response curve”, and the “average predicted tone response curve”, an estimate of the true tone response curve for the color channel can then be mathematically obtained, wherein the true tone response curve defines a predicted actual response for the printer for each addressable print location in the spatial range. The “predicted” and “average” tone response curves are obtained using the 2×2 binary printer model.

摘要： An image processing method involves processing image data indicative of an image represented with a prescribed number of input tones by each of pixel groups composed of a plurality of print pixels, and generating dot data representing a status of dot formation on each of the print pixels to be formed on a print medium. The method includes preparing a first conversion table and a second conversion table, determining the pixel group tone value in response to the input tone value corresponding to the pixel group, converting the determined pixel group tone value into the code values for each of the pixel groups, by referring to the first conversion table, decoding the acquired code value into the output dot arrangement for each of the pixel groups, by referring to the second conversion table, and outputting the dot data in response to the output dot arrangement.

摘要： A method for reducing the occurrence of print artifacts in an imaging machine includes the steps of applying an electronic printhead skew correction to image data corresponding to at least one of a plurality of image planes, e.g., of a cyan image plane, a magenta image plane, a yellow image plane and a black image plane, to generate skew corrected image data. Thereafter the associated halftone screens are modified to eliminated halftone noise introduced by the electronic printhead skew correction. If text characters are present, block boundaries are effectively shifted to reside in the spaces between adjacent text characters.
