Abstract

In Part I of this study, presented at IS&T's 19th Non-Impact Printing Conference, we tested the validity of current light-fade end-points for predicting the print-life of consumer digital output prints. It was demonstrated that current light-fade end-points generally under-predict the print life of home consumer prints, as perceived by typical end-users. The objective of Part II of this study is to go into more detail about the first-phase conclusions, as well as to assess possible alternative metrics. This study investigates how well end-points derived from colorimetric parameters correlate to end-user perception. End-points are evaluated based on both the 1976 CIELab and CIE-2000 color difference formulae. Color regions of interest, such as skin tones and neutrals, are looked at independently to improve the correlation of colorimetry-based metrics to the psychophysical results.
