  • Patent number: 8379266
    Abstract: Systems and methods are provided for generating at least one look-up table, wherein the look-up table holds at least one luminance value in a second color space. In some embodiments, the luminance value can be computed for distinct combinations of color component values corresponding to a plurality of color components in a first color space. The method comprises computing at least one luminance value in the second color space based on a portion of the color component value combination; deriving an address in a look-up table based on the portion of the color component combination; and storing the computed luminance value in the look-up table at the derived address.
    Type: Grant

  • Publication number: 20090086272
    Abstract: Systems in accordance with the presently claimed invention use parameters to choose the correct output file for translating the color values in a print job into device specific values in an output data file that may be used for printing. A data structure, such as a linked list of parameters, may be used to identify the correct output file to be used by the printer to form the correct device specific data file. The color values for each pixel in the device specific data file may allow a printed document to exhibit high color quality.
