We propose a novel color mapping method that generates smooth color transition and can accommodate the color
preference. The method consists of two stages; rough calibration and black generation. The rough calibration process
generates a three dimensional (3-D) Look-Up-Table converting input RGB data to printable CMY values. When the 3-D
LUT is created, a new intent for color mapping, target color is internally used. The target color is predefined from a
reference color book based on the color preferences of testers involved in the target definition phase. All of the input
data of the 3-D LUT are mapped to the printable values in a printer based on the target color, and then simply converted
to CMYK values. We evaluated the proposed algorithm comparing with a commercial printer profiler and found that the
proposed algorithm makes better printing quality.
