Abstract
A profile is created for making correspondence between a lattice point in an ink color space composed of ink colors and a lattice point in a device-independent color space by: defining 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 the profile by making correspondence between both.
