CONVERSION TABLE GENERATING METHOD, PRINT METHOD, CONVERTER, AND PRINTER

摘要

PROBLEM TO BE SOLVED: To provide a method for generating a color conversion table wherein color fluctuation in a gray color is less. SOLUTION: The method for generating a conversion table for converting a gray value into a non-gray value includes steps of: deciding a prescribed value in an L*a*b* color space as a non-gray value after the conversion; deciding a white point in the L*a*b* color space so that the non-gray value after the conversion belongs to the same quadrant as that to which a prescribed value in the a*b* color plane belongs; deciding a target axis passing through the prescribed value and the white point so that at least a value on the target axis between the prescribed value and the white point belongs to the quadrant; and creating a conversion table for converting a gray value on the L* axis into a non-gray value on the target axis.
