1. A method of replicating color images created on a first printer on a second printer or monitor comprising: printing a color chart having a plurality of predetermined color patches with the first printer; measuring said color patches to obtain colorimetric data; transmitting the colorimetric data to a computer; initializing a Neugebauer model with said colorimetric data; optimizing global parameters of the Neugebauer model on the computer; optimizing parameters of the Neugebauer model associated with Neugebauer primaries; optimizing parameters of the Neugebauer model that vary with the first printer coordinates; generating a first characterization file for the first printer; obtaining a second characterization file for the second printer or monitor; obtaining image data for first image to be replicated; converting the image data from the first characterization to the second characterization; and creating second image with the converted image data on the second printer or the monitor.
