    摘要： A method of controlling a printer to print of an image, the printer having a predetermined marking material printed dot size, the method comprising the steps of rasterizing the image and defining halftone super pixels within the image, calculating the average density of the marking material within the super pixels, selecting a pattern for marking the pixels within the super pixels as a function of the printed dot size so as to expand the distribution of printed densities printable by the printer.

    摘要： A method of printing an image with a printer having magnetic ink character recognition (MICR) toning capability, the method comprising the steps of: converting the image into a digital bitmap comprised of an array of pixels wherein each pixel is assigned a digital value representing marking information; defining each pixel as either a background pixel, interior pixel, or an edge pixel; and, reassigning the digital value of one or more edge pixels or interior pixels independently, thereby altering the concentration of magnetizable substances within the image when printed in order to improve the readability of printed characters by reading instrumentation.

    摘要： A method of printing an image utilizing a printer having print nonuniformities, the method comprising the steps of converting the image into a digital bitmap comprised of an array of pixels wherein each pixel is assigned a digital value representing marking information comprises defining each pixel as either a background pixel, interior pixel, or an edge pixel; and, reassigning the digital value of one or more edge pixels or interior pixels to lower values independently in order to reduce toner consumption. The rendering of the present invention occurs post RIP.

    摘要： Computation of digital gains and offsets used in digital scanners for shading correction (linearity correction) is particularly vulnerable to imperfections in the reference strips, particularly the light reference strip. It is extremely difficult and expensive to create references which are completely free of imperfections or contaminated in some way. This invention eliminates artifacts caused by the presence of small imperfections on the references. It does so by detecting the presence of an artifact and then excluding data contributed by the artifact from the calibration computation process.
