Predicting ink behavior on a substrate m can be accomplished by combining spectral modeling algorithms with spectral ink measurements, as well as the substrate's colorimetric properties. A continuing trend in package printing is the increasing complexity of jobs and the use of multicolor printing, while at the same time meeting brand owner demands to reduce time to market. Many packaging jobs require different combinations of inks, substrates, screening, and other variables. For example, a chocolate wrapper might have two browns; fruit juice might have oranges, greens, and reds.
