摘要

In color conversion definition creating method and color conversion definition creating apparatus for creating a color conversion definition defining a relation of data conversion between RGB data for a printer and CMYK data for printing to perform printing in which a color of an image outputted by a printer receiving the RGB data and outputting the image is reproduced, a data conversion algorithm 60, in which color conversion parameters customized by a skilled person in color customizing are set up, is used to determine a curve of K on a gray axis (a first K-function creating section 54), and the data conversion algorithm 60 is altered into a color conversion algorithm faithful in colorimetry as to K to determine values of K of the whole color spaces (a second K-function creating section 54). With respect to C, M and Y besides K, values are determined so that calorimetric values are matched.
