Abstract:
1. A profile creation method of creating a profile which makes the correspondence between a lattice point in an ink color space composed of ink colors and a lattice point in a device-independent color space, the method comprising the steps of: defining by a computer a virtual force acting on a focused lattice point in a device-independent color space and obtaining the focused lattice position in a stable state reached when the virtual force acts on the focused lattice point; and working based on a transform model for transforming a lattice point in the ink color space into a lattice point in the device-independent color space to obtain a lattice point in an ink color space corresponding to a focused lattice position in the stable state and creating by a computer a profile by making correspondence between both, wherein the virtual force includes a resistive force whose magnitude is proportional to a speed for movement of the focused lattice point.
