Abstract
An original reference value table containing converted values of image data on the entire color space is made based on known look-up tables of a printer and a correction printer, and a reference value table is wholly or partly corrected adequately so that the results of printing performed by the correction printer by referring to the original reference value table may be similar to the results of printing performed by the printer while the mutual non-linearity of converted values held in the reference value table is maintained, thus making a reference value table with an improved precision of color reproduction.
