Abstract
In order to create a profile that associates lattice points defined in an equipment-dependent color space with lattice points defined in an equipment-independent color space, a reference profile that associates a plurality of lattice points in the equipment-dependent color space with lattice points in the equipment-independent color space is retrieved. A virtual force that acts on a focused lattice point in the equipment-independent color space is defined, and a position at which the focused lattice point is located in a steady-state in which the virtual force acts on the focused lattice point is calculated. The reference profile is referenced in order to retrieve a lattice point in the equipment-dependent color space associated with the position of the steady-state focused lattice point. A profile is created by associating the position of each steady-state focused lattice point with a lattice point in the equipment-dependent color space.
