The present invention relates to a color management method for the conversion of internal color appearance space color values to CMYK device value, by interpolating CMY values from a plurality of CMY to color appearance space lookup tables, wherein each CMY table is associated with a specific value of K. A target internal color value is received and one of the plurality of CMY lookup tables is selected based on a lightness value and neutrality of the target internal color value. Next a CMY value is interpolated from the selected lookup table and the target internal color value. Finally, the interpolated CMY value and the associated K value from the selected table is provided as the converted CMYK color value. In this way, the present invention is able to control the output K value in a color appearance space to CMYK conversion. Accordingly, both neutral and non-neutral colors can be reproduced with better accuracy and higher quality.
