  • Method of creating 4x4 LUTs using a source and destination ICC profile
    Publication number: 20070211268
    Abstract: A 4×4 LUT comprises a K to K LUT merged with a CMYK to CMYK LUT with values ranging from [0, 0, 0, 0] to [0, 0, 0, 255], said 4×4 LUT written to a known file format. A method for creating 4×4 look up tables (LUTs) uses the source and destination ICC profiles. A K to K LUT is built, a CMYK to CMYK LUT is built, the K to K LUT is merged with the CMYK to CMYK LUT, and the resulting LUT is written to a known file format. Such a process is important since it solves the issue of preserving K in a CMYK to CMYK transform while adding the performance improvement of a 4×4 LUT.
