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.
