The problem is what it implies about paper permanence.. One would reasonably expect it to have longevity significantly beyond that of more widely used paper media. >Many years ago I bought an Ansel Adams print, (dogwood blossoms), at the >Yosemite Gallery.

Well, >over the years the mat has most definitely yellowed, and quite a bit. > Generally, Archival Matte has been taken to mean acid free... The focus there has always been on making a matte that will not add to any degradation or additional aging of the matted media.. So, yellowing of the matte is acceptable as long as it does not cause yellowing of the print, etc.. That's part of the confusion, the term is used differently... > >The white dogwood blossoms are pure white.

Here are two: 1) It is based on a threshold % of image fading.. What happens when with color images you get seriously skewed differential fade? Isn't a print that fades that way worthless sooner than one that fades at a fairly consistent rate across the spectrum? 2) Witness how the "orange shift" fiasco caught EPSON and Wilhelm off-guard.. Only time in the REAL WORLD (not the MTV version either) under a variety of conditions can tell any of us for sure.. >But if they last as long as a silver print, maybe that's good enough. > > > I think that if B&W images last a long as an archivally processed fiber based silver print, I'll be more than happy... For color images if they make it as far, say, as Fuji Crystal or Ilfochrome prints, I'll be happy.
