Slightly more info for you to file away...

The i1UV and DTP20UV have slightly different UV fliters, the cutoff 
is at a slightly different place and can be see if you graph the 
spectral measurements of paper white using a paper that has OBA (like 
EEM). Which one is more correct would be difficult to determine. The 
colors are also slightly effected, and certain printers show more 
change in the color than other printers. I just measured some targets 
for an HP 8450, and it shows more change between the two devices than 
the ink that I use, so I would conclude that their inks may contain 
some brighteners. And here is a picture for you:
