Patent ID: 8014028

Claim:
A color management method for using a rendering model encapsulated in a transform-based profile in a measurement-based color management system (MBCMS), the method comprising: converting a predetermined collection of source device color values to generate perceptually rendered values using the rendering model encapsulated in a perceptual transform of the transform-based color profile; converting the perceptually rendered values to generate perceptually rendered appearance values of a color appearance space using predefined viewing conditions; mapping the generated appearance values to generate destination device color values within a color gamut of a destination device using a gamut mapping model, wherein the gamut mapping model uses a perceptual intent reference medium gamut (PRMG) boundary description and a gamut boundary description of the destination device to perform the mapping, wherein the PRMG represents the color gamut of an idealized medium; constructing a measurement-based color transform from the predetermined collection of source device color values and the corresponding destination device color values generated by the gamut mapping model; and converting color values of an image generated by the source device to color values of the destination device using the constructed transform.
