Color conversion of image data

A color conversion system, comprising:

• an output imaging device having a color gamut and operable to present image data from an input imaging device, wherein the image data has a plurality of color values;
• and
• a processor operable to receive the image data from the input imaging device, generate a lookup table of color values based on the model, map the color values of the image data to a color gamut of the output imaging device, compare the mapped color values to the color values of the lookup table to retrieve from the table corresponding color values in the color gamut of the imaging device, and process the retrieved color values to convert the color values of the image data to the color values of the output imaging device.

A printing system, comprising:

• a printer operable to print to a tangible medium;
• and
• a printer controller operable to process a print job from a host system and transfer the processed print job to the printer, wherein the print job includes image data having color values and wherein the printer controller comprises a processor operable to generate a CMYK to CIELab model, generate a table of CMYK color values and corresponding CIELab color values based on the model, map the CIELab color values of the image data to a CIELab color gamut of the printer, compare the mapped CIELab color values to the CIELab color values of the table to retrieve corresponding CMYK color values, and process the retrieved CMYK color values to convert the CIELab color values of the image data to the CIELab color values of the printer prior to printing to the tangible medium.
