Digital BW, The Print

I see it under fluorescent lighting, but really, the paper itself has 
a bit of a yellow cast and is really what I think is giving the 
prints the color cast and not a typical inkjet metamerism.  If you 
walk around with a hp print and a traditional b&w print for reference 
you will see it though.

Yeah, that's the rub.  With hp paper and Wilhelm results you can 
argue 100+ years, with anything else you are stuck making some flimsy 
personal replacement guarentee or something.

Mounting is a problem though.  For archival purposes most people 
don't like photos mounted even though they hang much better when they 
are, especially these hp prints.  Maybe hang mounted prints and give 
the buyer the option to get it unmouted if they prefer.  Isn't this 
an issue for anyone else?  In general, are people still dry mounting 
or just hinge or corner mounting photos?
