Digital BW, The Print

My best guess is that 50+ is safe.

Recall, of course, that these ratings are years of predicted display in
rather specific conditions.  The good news is that in photo albums, properly
stored, these pigmented inksets probably are truly archival.

The UC neutral prints are rated at 100+, and they are clearly superior to
the current VM inkset in my fade testing.  The old MIS archival color inks
were limited by the first generation yellow, which RIT rated at 49 years (if
memory serves me).  The VM inkset is better than this old yellow.  So, I'd
guess it's in the 70 year range (with good paper).
