Control apparatus, multidimensional color correction method and non-transitory computer-readable storage medium storing multidimensional color correction program

摘要

A control apparatus includes a control unit, and a raster-image processor that performs color correction to correct colors of a user printing device into colors of a standard printing device by using a multidimensional LUT and performs color conversion by using a printer profile for the standard printing device and a target profile. The control unit creates the multidimensional LUT including a first LUT and a second LUT, and compares chromas of each fully saturated secondary color of the user printing device, the standard printing device and the target colors. On judging that the chroma of one fully saturated secondary color of the user printing device is greater than that of the standard printing device, the control unit instructs the raster-image processor to perform the color correction while specifying use of the first or second LUT according to a comparison result of the chromas.
