Smoothing lattice positions |
June 2, 2009 |
| 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 |
