Abstract:
1. A color printing system, comprising: a color printer adapted to receive an image and text file and an international color consortium (ICC) profile associated with the color printer, printer inks and the printer paper, and adapted to print a color patch using chosen ink and chosen paper; a color measurement module adapted to generate a spectral measurement of at least one color output of the color printer; and a difference file containing a difference between a computed color patch and a measured color patch, wherein the printer contains information regarding: a set of ink files describing inks to be put in the color printer, a set of paper files describing papers to be fed into the color printer, and a set of spectral files which describe a spectral reflectance of a set of patches for a particular ink and paper combination; wherein the color printing system is adapted to create a corrected color consortium (ICC) profile for the color printer, when at least one of an ink and a paper is replaced in the color printer, wherein when an ink is replaced, an ink characteristics replacement module is adapted to modify the ink characteristics, by replacing the characteristics of the removed ink with the characteristics of the new ink, and wherein when a paper is replaced, a distributed profile assembler is adapted to combine the new paper characteristics with the printer characteristics, the ink characteristics and the joint paper, ink and paper characteristics.
