I disagree that this is a significant issue with most 
artwork.  My wife and I are art collectors (and I'm 
an artist and photographer).  We have oil, acrylic, and
watercolor paintings, as well as monochrome intaglio 
prints and stone-plate lithographs that are over 100 
years old.    Some of these are displayed in rooms with
incandescent(halogen) lights, some under fluorescents,
and some under daylight (in my north-facing studio - not
direct sunlight).    I've never seen any significant color
shift between these different light sources.  When it gets
dark out and I turn on the lights in my studio they don't
shift.

So I don't think the inkjet inks can be let off the hook 
that easily.

The RIPs do a good job.   See:
