Digital BW, The Print

I think this discussion has now completed a full circle.

It originally started with a discussion of acidity as a limiting
factor for print life then evolved to a discussion of all the other
weaknesses of modern inkjet inks and papers (acids, OBAs, surface
separation, binders in ink, oxidation, etc)

Then I posted this reply with my own results about acid levels in a
few paper coatings and papers using a pH pen:

At this point I'm not sure of the relative importance of the factors
that have been raised and skeptical of how long any of these prints
will last.  As long as it's longer than my Fuji Frontier prints I'm
happy as that's my alternative.

Will Epson luster, despite its RC composition, OBAs and surface
acidity really outperform cotton papers like Somerset Velvet?  In
Wilhelm years, yes, apparently, but in reality?  See here for the
9880: http://www.wilhelm-research.com/epson/9880.html

Also, John, the Harman FB Al Baryta doesn't do all that well relative
to standard Epson papers in the Wilhelm tests- except when used with 
HP pigment printers.
