Abstract

The accuracy of a six-color inkjet printing system was tested using object-color spectral datasets known to both span and exceed the system's spectral gamut. The theoretical basis of the system is the Yule-Nielsen modified spectral Neugebauer equation implemented in an iterative optimization process minimizing spectral RMS error. Results of the end-to-end system based on the reproduction of 170 object colors compiled by Vrhel, et al. show a mean ∆E*94 of 3.2 while 384 randomly selected printed color samples (in-gamut) were reproduced with a mean ∆E*94 of 0.9.
