Digital BW, The Print

I agree. It would be great to have a comprehensive list of papers 
that use OB's. What I don't understand is 1) why OB's are used if 
they cause an otherwise good (but perhaps less white) paper to 
noticeably yellow over time (of course, the exception might be those 
cheaper papers that are used for proofing) and 2) if OB's are a 
problem, then why do many printers knowingly use papers that contain 
OB's. I've heard, for example, that some people on this list use EAM 
for prints that they sell. Is yellowing a problem with EAM or is it 
in truth not noticeable enough to warrant a change of paper.
