  • Publication number: 20130250344
    Abstract: A computer implemented system and interactive method for selecting finishing options for a print job are disclosed. The method includes receiving a print job which includes a document to be printed and associated job ticket information. Finishing options available are displayed using an interactive virtual representation of the document as it will be printed and a visualization of the document as it would be rendered with a user selected finishing option(s).

  • Patent number: 8451521
    Abstract: What is disclosed is a novel system and method for converting a set of L*a*b* values to CMYK color space in which all CMYK formulations that produce each L*a*b* value are found and enumerated. The CMYK formulations are found through a search algorithm starting with the lightest L*a*b* values then visiting neighboring L*a*b* values until the entire L*a*b* color set has been processed. The CMYK space is tessellated into a set of pentahedrons, and for each L*a*b* value, an enclosing pentahedron is found and the CMYK values corresponding to where the locus of this point penetrates each surface is recorded. Adjacent pentahedrons are then visited and this process continues until the gamut boundary is reached. The result is a piecewise linear representation of the CMYK locus containing all values that will give the target L*a*b* value. The present method provides a flexible and powerful approach for solving color management problems.
