My limited experience with Piezo inks and different papers is that 
initially the print comes out with a slight green cast, regardless of 
what paper I use it on, but if I "develop" it in the sun for a day (or 
less), the prints take on a more sepia or warm tone. Papers I 've 
used are Concorde Rag, WR, Orwell, Cone Tech Matte, 
Somereset Enhanced and Xtreme Gamut Satine. 

Placed some test prints in a black box to compare with prints 
placed in a window for 10 days, and te prints in the box were 
slightly warmer than a fresh print coming out, but not nearly as 
warm as those in the window. Did not notice a density shift.
