Abstract: 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.

Abstract: 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.

Abstract: Systems and associated methods provide for converting an RGB color image to a grayscale image via a lookup table of correction values. The lookup table is generated and used to compensate for errors in converting the color image to the grayscale image. The lookup table is generated by generating a reference image having pixels with color values in the RGB color space, converting a first copy of the reference image to a grayscale reference image via interpolation, and converting a second copy of the reference image to an intermediate image. The intermediate image comprises chrominance and luminance values (e.g., YCbCR or YCgCo). The chrominance values are removed from the intermediate image. The intermediate image is then compared to the grayscale reference image to generate the correction values. The lookup table may then be applied to a grayscale image that has been converted from the RGB color image.

Abstract: A method and system for mapping an input color value in an input color space to an output color value in an output color space comprising a lookup table mapping an input value to an output color value, the lookup table having n number of possible values for a first fixed color component and q number of possible values for a second fixed color component, wherein q and a number m of possible values for t color components in the input color space are less than n. Surrounding input values are determined in the lookup table in a t dimensional space, wherein each surrounding input value has a same value for the fixed color component(s). Surrounding output values to which the surrounding input values map are determined. The determined input and output surrounding values and the input value are used to estimate an output value corresponding to the received input value.

Abstract: Methods and systems herein provide for color conversion. Such color conversion includes a method of optimizing gray component replacement in a color image that includes receiving a color image from an input imaging device (e.g., a digital camera, scanner, etc), determining a color gamut of an output imaging device, such as a printer, and generating a CIELab to CMY numerical model to convert the color image to a color space within the color gamut of the output imaging device. The method also includes generating a CMYK to CIELab numerical conversion model, removing a portion of CMY color values generated from the CIELab to CMY numerical conversion model, and replacing the removed portion of the CMY color values with black color values. The method also includes optimizing CMYK color values via a multidimensional optimization using the CMYK to CIELab numerical model.

Abstract: Provided are a method, system, and program for decoding compressed data. Compressed data is received and decoded. An error is detected while decoding a first location in the compressed data. A reentry data set is accessed having a pointer to a second location in the compressed data following the first location and decoding information that enables decoding to start from the second location. The second location in the compressed data is accessed and the decoding information in the accessed reentry data set is used to continue decoding the compressed data from the second location.
