Abstract:
1. A system for iteratively acquiring optical color measurements for device color profiling comprising: a scanner input operative to receive a first color measurement data set corresponding to a measured value for each of a plurality of L discrete printed color patches in an M row by N column planar array thereof, wherein the color measurement data is encoded in a first multidimensional color space, and wherein L, M and N are positive integers greater than 2, and wherein L is less than M×N; a color data input operable to receive color data corresponding to each measured value, wherein the color data is encoded in a second multidimensional color space; a display operable to generate a visual rendering of display color patches arranged in M rows and N columns and corresponding to each printed color patch, which visual rendering is completed from color measurement data encoded in a second multidimensional color space; a profile generator operable to generate profile data corresponding to a transition between color data and color measurement data in accordance with a relationship between available corresponding printed color patches and displayed color patches; a partial result generator operable to generate, when L is less than M×N, a visual indicator corresponding to one of the M rows on the display, which row corresponds to a row wherein the current L value resides; an input operable to receive at least a second color measurement data set uniquely defined from the first color measurement data set, and which second color measurement data set includes a plurality of the M×N patches not found in the first color measurement data set; and wherein the color profile generator is operable to further generate the profile data in accordance with the second color measurement data set.
