Cathryn,

I tried to find the fairly recent posting on the ConsDist list in
regards to this but couldn't find it. The only "archival" quality
printer inks that I am aware of are the Epson inks that have been
tested for stability.

Perhaps one of the other conservators who are on the list can post
more specific information on them as I don't have it readily at hand
right now.

Cheers!
Dave

This keeps them from fading much longer than if unsealed (go figure).  The wall graphics in our special exhibits gallery have been in place since Nov '04 and most (but not all) are holding up really well.  The gallery lights are UV filtered, and the light levels on the graphic panels are pretty high.  Unsealed graphics in the same room have been replaced twice since the exhibit opened because of fading.
