Digital BW, The Print

Two more quick points, the yellowing I've seen has definitely not been
confined to PhotoRag or even Hahnemuhle, but other coated art papers
as well. Also, the packaging tape used on more recent orders has been
done with a tape that seems different, and I've experienced no recent
yellowing out of the box, as Jim said they seem to have addressed this.
Lastly if it's helpful, this quote from someone who seemed to know his
stuff-

"All rubber based PSA adhesives we have tested turned
the coatings (fine art paper) yellow. This not only will happen at the
point of
contact but the contamination can travel/as a matter of fact if you
have a poly
print bag (not Polyester) and put a piece of rubber based tape on top
of it the
print inside will yellow. USE ACRYLIC ADHESIVE PSA."
