Abstract
Seven color separation criteria are evaluated and compared for multi-ink
printer characterization, which is a union of five 3-ink and six 4-ink cellular
Yule-Nielsen spectral Neugebauer (CYNSN) submodels. In the experimental stage,
testing reflectances from printing samples and Munsell color samples are employed.
The results show that the prediction and actual accuracy of all the seven selection
criteria are approximately the same for printing samples. As for the Munsell
samples, the combE<sub>00</sub> & MI outperforms other selection criteria because it
combines one color difference with two metamerism indices, which are important for
the heterogeneous samples during prediction.
