Digital BW, The Print

To be clear, the kind of yellowing I am referring to is unique to coated inkjet papers. Yellowing due to other factors like UV that affects all art (many objects actually) is not the issue I brought up. The yellowing I am talking about can occur literally overnight, depending on how much moisture is available to accelerate the reaction. It is a reaction between the properties unique to inkjet coatings, and particular chemicals. Many of these are common to adhesives or plastics, that slowly outgass to avoid drying and becomming brittle. Even the little rubber feet on my small paper trimmer, if placed on inkjet paper, will make little yellow stains in precise shape on the paper in a day or two. Believe it or not, Epson's own vinyl coated roll spring will do it to the roll it secures.
This is not a UV problem, in fact UV can bleach it back out and save a print. Mark McCormick-Goodhart and Jon Cone both, separately, told me it is most likely sulfur.
Many people here or in the wider community very active with inkjet have had unfortunate experiences with this issue, losing large bodies of work, and even clients.
I find we have to constantly educate and re-educate about this issue. People assume their knowledge and experience about handling art carries over into these new materials. I've had many a re-print job because frame shops either damaged the prints with rough handling (even throwing out all the interleaving and careful packaging, and just stacking and shuffling them, putting other things at their work space right on top of them) or using previously acceptable adhesives in some part of the assembly that then outgassed and yellowed the coating..
Everything is changing, a top expert ten years ago armed with a lot of knowledge and experience may quickly ruin an inkjet print, because they haven't been on the front lines like the users. These are the people that really ought to get up to speed and strongly support Aardenburg Imaging & Archives.
I appreciate everyone's replies. My specific issue is resolved. This was just to mount some text printed out and mounted to foamcore, and needs to last a few months at best. The imediate yellowing was the concern.
However continued attention to these issues is very important for the survival of this generation's artistic output. I also hope it leads to development of less sensitive coatings. To suggest some kind of information about care and handling from the manufacturers would be an understatement...

In general, spray adhesives are not archival so I have never concerned myself with the chemical properties and long term print reactions. Short term print yellowing tends to be due more to the surface of the print not being protected with glass, and being exposed to significant ultraviolet radiation (direct sunlight).
