Abstract:
The purpose of the present invention is to create a color conversion table with good gradation using a plurality of inks from a printer. Provided is a method for creating a color conversion table, the method comprising: a virtual color value determination process in which a plurality of virtual color values at a lattice point in a color conversion table in a virtual color space are determined; and an ink amount determination process in which a combination of ink amounts at the lattice point in the color conversion table is determined on the basis of a predetermined conversion coefficient and the virtual color values. At least one of the virtual color value determination process and the ink amount determination process is executed using a cubic spline function that is defined from the plurality of virtual color values or the ink amounts.

Claim (Index 3):
The method for creating the color conversion table according to  claim 1 , wherein\n at least one of the virtual chromatic value determination step or the ink volume determination step defines a first cubic spline function, the first cubic spline function having the virtual chromatic value or the ink volume as a dependent variable and a value of a lattice point in a device color system as an independent variable with respect to three consecutive lattice points to be processed, the three consecutive lattice points to be processed including an intermediate lattice point with the virtual chromatic value or the ink volume to be determined and two end lattice points with the virtual chromatic values or the ink volumes that are already determined sandwiching the intermediate lattice point, defines a second cubic spline function, the second cubic spline function having the virtual chromatic value or the ink volume as a dependent variable and a value of a lattice point in a device color system as an independent variable with respect to another three lattice points with the virtual chromatic values and the ink volumes that are already determined, the another three lattice points being respectively adjacent to the three lattice points to be processed in a direction different from a direction of definition of the first cubic spline function, the second cubic spline function being defined in a direction identical to the direction of definition of the first cubic spline function, and determines the virtual chromatic value or the ink volume at the intermediate lattice point to minimize a sum of squares of differences between a first-order derivative parameter determined by the first cubic spline function and a first-order derivative parameter determined by the second cubic spline function of respective sets of the lattice points adjacent to each other in the direction different from the direction of definition of the first and second cubic spline functions.
