摘要： Force K processing is presented to replace gray color values of input data with only levels of black ink/toner when color management is not specified in the print job. A system converts input data of a print job to a CMYK color space of a printer by processing a lookup table of color values for the color space of the input data based on a detected color space of the input data to identify gray color values of the lookup table. The system also determines that these gray color values produce an output in the CMYK color space of the printer that includes one or more of cyan, magenta, and yellow color components. The system replaces the gray color values with black color values and corresponds the black color values of the lookup table with gray color values of the input data for conversion of the input data.

摘要： Systems and methods for color conversion from one CMYK color space to another CMYK color space. The system receives a color defined by a first coordinate in the first CMYK color space. The system converts the color to a second coordinate for the second CMYK color space, and determines a location in a perceptual color space for each of the first coordinate and the second coordinate. The system further identifies a distance between the locations in the perceptual color space, and reduces the distance in the perceptual color space between the two locations by iteratively revising the second coordinate in the second CMYK color space while holding the black level of the second coordinate constant.

摘要： In summary, the present invention provides a method, apparatus and program product for calculating an estimate of the amount of toner coverage required for printing print data defined in a compressed data stream. The estimate is obtained with reduced processing by obtaining coverage data from a partially decompressed formed of the data stream and using this to obtain the coverage estimate, thus removing the need to do a full de-compression of the data stream. For example the coverage data is a count of toned pixels for at least one intensity level.

摘要： Methods and systems herein provide for calibrating for a plurality of different paper types. In one embodiment, a system for calibrating a printer includes a measurement module operable to detect colors printed on a first tangible medium by the printer and convert the detected colors to a detected color characterization. The system also includes a storage module operable to store a calibration file. The calibration file includes color characterizations of a plurality of different tangible mediums and each color characterization includes color measurements for one of the plurality of different tangible mediums obtained from the printer via the measurement module when the printer is calibrated. The system also includes a calibration module operable to compare the detected color characterization to at least two color characterizations of the calibration file and determine an adjustment to an output color scheme of the printer based on the comparison to calibrate the printer.
