Abstract
A method for determining a blended color transform for use in producing printed colors on a color printer having at least four device color channels, comprising: forming first and second color transforms, wherein the first color transform produces printed colors that have a reduced sensitivity to color printer process variations in at least a first region of color space that includes a near-neutral color region, and wherein the second color transform produces printed colors that have a reduced image noise visibility in at least a second region of color space; defining a blending function which computes weighting values for the first and second color transforms as a function of input color values; and using a processor to determine the blended color transform by blending the first color transform and the second color transform, responsive to the blending function.
