ABSTRACT:
A method for modeling color halftones that reduces both the number of parameters and the number of measurements needed to characterize an inkjet color printer. The method is based on the eigenanalysis of sample reflectance data and a probabilistic analysis that considers light scattering on the paper substrate as a breakage process governed by a log-normal distribution. The method estimates the reflectance of a print color by characterizing colors as a multiplicative composition of primary color reflectances rather than as an additive mixture of primary and secondary color reflectances as suggested by the theory of Neugebaeur.
