As would I, John, but I am not willing to get obsessive about it, and I most certainly am not willing to risk shortening my own productive years to do it. >> I have a friend who said the exact same thing 20 years > ago about her 20x24 polaroids done in Cambridge.

I seriously doubt that overspraying either would have made them archival, and nobody ever made any archival claims about either Polaroid or C-prints. Both of those media are inherently incapable of being so. If there was an evaluation system in place back then, we were kept unaware of it, obviously for good reason. Which in turn led to Wilhelm & RIT testing, etc. We now have a much better idea of where things stand, so I have to ask myself: if a no color-component carbon ink gives a number of around 150-200 years of DISPLAY life (nobody interested in making artwork actually last that long keeps a piece on display constantly), how much trouble am I willing to go to for twice that? Obviously less than you. >I've looked at a lot of fine prints that are from the 16th - 19th > centuries and I"m glad they outlived their authors.

Who's information and claims are you trusting now? I think we're both old enough to have seen many such claims by industry/FDA/medical establishment get proven wrong, sometimes in just a few years, but almost always after a considerable amount of damage has been done.

All of this material has improved hugely in just the last generation; in another generation concerns about longevity may become purely academic. In the meantime, I'll take the approach of minimizing the color content, and reccomending display behind glass only. You do whatever makes sense to you, John, just do me the favor of not suggesting across-the-board spraying of all our work again, the hair on my arms stiffens just thinking about it... oh, no, sorry, that's overspray from the varnish...
