I would consider inks a can of worms. I am sure there are research papers
on ink life. I see degraded paper more often than faded ink but my experience
is quite casual. I will be interested in what others think.
Inks are a can of worms! What I have seen is more paper degradation than ink
fade. Back in 2006, ran a series of ink jet prints in a sun light aging test -
Epson Ultrachrome inks on various papers. Made the print, cut in half and
taped one half to a south facing window (uncoated glass so the UV cut-off is
about 330 nm) and the other half went into a dark box. About 4 months exposure
to New Mexico summer sun. After “aging” compared the two images and there was
no significant ink fade but there were color shifts in the base paper. Stored
all of the samples in a light tight box and after about 10 years of time, the
exposed papers had developed more color compared to the unexposed paper
samples. Checked again today (15 years) and the base papers that were exposed
to the sun had yellowed compared to the unexposed samples - the question is
paper stability rather than ink stability.
