Patent ID: 8203752

Claim:
A computer implemented method of generating a multidimensional printer profile look-up table (LUT) for color correction, the method comprising: a) receiving a plurality of target color signals defining a respective plurality of target color nodes in a multidimensional device independent color space; b) generating for each of the nodes an initial estimate of a respective multidimensional device dependent color space representation; c) generating for each of the nodes a respective multidimensional gain matrix, the gain matrix providing one or more gain functions associated with each node to provide a calculated multidimensional corrected device dependent color space representation of a target color as a function of the initial estimate of the respective multidimensional device dependent color space representation, and a color error associated with initial estimate of the respective multidimensional device dependent color space representation relative to the respective target color; d) generating an initial multidimensional printer profile LUT by associating each of the plurality of target color nodes with the respective initial estimate of the device dependent color space representation and the respective gain matrix; and e) generating a final multidimensional printer profile LUT based on the initial multidimensional printer profile LUT by performing one or more iterations to generate calculated device dependent color space representations of the target color signals and associating the calculated device dependent color representations with the respective nodes of the final multidimensional printer profile LUT.
