Digital BW, The Print

After letting  2200 prints (on Epson paper) dry for several days and 
then, matting and framing, I notice a film deposit under the glass 
that matches the image. It happens in as little as 3-4 weeks and 
really dulls the appearance of the photo(b&w or color)and must be 
cleaned. Forced drying helps to greatly reduce this problem. 

I have seen this problem with older ink jet prints also. Any thoughts 
on this?

I've seen this on Epson 870 prints, but I haven't put any of my 220 
prints under glass yet.

BTW, someone here just criticized me for complaining that it was 
hard to find inkjet printers with the kind of deep-down intellectual 
curiosity about the chemistry of inkjet printing that was easy to 
find among some darkroom printers.   What practical use was such 
knowledge, he wondered.

I think rr6x7's question is a good answer to why such knowledge 
might be useful.
