Practical Ink Selection for Multispectral Printing in the Graphic Arts Industry
  DOI :  10.2352/CGIV.2006.3.1.art00035  Published OnlineJanuary 2006

This paper shows how to optimally select aqueous inkjet inks in order to reproduce objects typical for graphic arts use. Using a modified 7-channel inkjet printer various inks are printed on a proofing paper exhibiting no optical brighteners. First different methods for linearization and ink limitation are examined and discussed. This is followed by an analysis of the colour- and spectral gamuts, namely the spectral gamut index, resulting from the chosen primaries. A spectral reference dataset has been created representing the spectral variability of offset and gravure printing processes. A modified spectral Neugebauer model is used for the prediction of the spectra from driving code values while linear regression iteration was used for the backward model. Finally the resulting spectral matching accuracy is evaluated.
