Digital BW, The Print

I did notice they said that. At least they're bieng straight with us on 
that point. As for the remaining OBA's, some seem to hold up better 
than others. Photo Rag has OBA's, and and you pointed out many other 
papers, but a number of them don't yellow over time the way some RC 
papers do. I'd be curious to know if that's a function of the OBA's not 
burning off as quickly, or simply not yellowing as they do burn off.
For me the test is going to be the very scientific (NOT!) but brutal 
Florida Room test. It's warm, humid, and brightly (but indirectly) lit; 
if a paper makes it a month in here without yellowing, it's worth 
further testing. So far my champ in RC papers has been Sunset semi-
matte, sold by Lexjet; It has outlasted E-prem. semi-matte, which 
generally gets pretty high Wilhelm numbers. Problem is, the base color 
is very cold, in a particulalry bothersome cyan-blue direction, so I'm 
still looking.
