That would make a lot of sense - I can well appreciate the scientific
reasons for this. It then makes one wonder whether there are similar
anomalies between the spectral reflectivity of different ink
formulations that are "visually" the same. I'm sure there are,
especially when the substrate (paper) is factored in too. And the
spectral output of the viewing illuminant not being the same as the
one in the spectrometer...and...and.... :-0

Perhaps we worry too much!! I spent hundreds, thousands even, of hours
in a darkroom, processing my own colour prints. I soon learned that a
colour analyser was a guide rather than an absolute assessment - the
*eyes* had it in the end!
