ABSTRACT:
First colorimetric data with respect to device data C, M, Y with device data K=0 % are determined as a first color-predicting LUT, and second colorimetric data with respect to rough device data C, M, Y, K are determined as second color-predicting LUT. Third calorimetric data with respect to device data C, M, Y, K having the same device data K are predicted from the second colorimetric data. A third color-predicting LUT representing a relationship of the third colorimetric data to the device data C, M, Y, K is determined from the third calorimetric data. The first, second, and third color-predicting LUTs are established as a desired color-predicting conversion relationship.
