1. A processor-readable medium comprising processor-executable instructions for mapping color data, the processor-executable instructions comprising instructions for: adjusting a degree to which BG color coefficient generation is similar for process-neutral and K-only neutral images to produce BG coefficients; adjusting a degree to which UCR color coefficient generation is similar for process-neutral and K-only neutral images to produce UCR coefficients; and mapping CMY color data to CMYK color data using the produced BG coefficients and the produced UCR coefficients.
