I'm curious if any one has tried any of the UV sprays like 
ImageShield or PrintGuard (or your favorite one) with the new 
PiezoTone inks.  Unfortunately my SN-PT 1280 cart arrived w/the 
blue meanies so I've been unable to start my "kitchen wall" tests.

During the Cone workshop I attended in Aug, Jon said the black 
ink has an additional component in it which is not a dye, but may 
behave like a dye.  He also said in post  
http://groups.yahoo.com/group/piezography3000/message/1941
0 (at the very end), they would fix real problems.  So I hope 
people are sending samples to him!

From my perspective, quad tone printing is still in it's infancy.  I've 
been with the Piezography system for 2yrs and it just seems to 
take some time to understand what happens.  For example, I ran 
Concord Rag tests for a year.  Even w/a UV spray, I won't dream 
of selling a print.  Another example, my William Turner 190 test 
has been running for 10 months.  Even w/ImageShield, the 
fading is strong enough to really bother me.  However, the same 
print in the living room, 2ply mat on back, 4ply mat on front, 
w/glass and QuickClips has much much better density.  The 
living room receives much less light.  In fact, C prints will fade in 
the kitchen after a year as a point of reference.

The original Piezography inks damaged 3 different printers of 
mine.  For me, there is no going back to them.  The new 
selenium inks look great so I'm waiting to see if the black 
problems can be resolved by modifying the ink.
