Digital BW, The Print

I have no data but since I've made reference to the breakdown of
previous assumptions about traditional processes I'll respond. I don't
recall where I saw it or do I recall any actual fade data. Somewhere
in my aging memory is a glop of several comments over the last few
years that collections were experiencing problems they hadn't
expected, so it's a topic I've bandied about perhaps too loosely, but
it's out there. I have heard reference to the partial toning problem
Paul refers to as well.
Also, here is an interesting discussion, based on a magazine article,
addressing various suppositions we held regarding mounting, and
mounting materials, as well.

Due to inks and coatings apparent sensitivity to pollutants, I've been
using this board though it may be overkill, please don't take this as
me promoting the product, only pointing you to an interesting article.
