Without double a gated spectro (and many hours of time) it is not possible to
account for the source and destination of all fluorescence in a given
inkset... so about the only thing we can practically manage is to determine if there
are paper whiteners, to allow some compensation for that (this option doesn't
really require spectral data) and model the appearance of a given spectra (and
assumedly the sample patch it was measured from) under a different light
source. Given your single light source standard comments up front, we're really
back to simply checking for, and allowing compensation for, paper whiteners.
