I agree that the UC inks are about the most stable I've ever worked
with and didn't mean to disparage them in any way.
When I profile presses, I typically have to measure dozens of sheets
and average them-it's a whole different game.

Ultrachrome shifts, not as much as dyes, but it DOES shift while it's

I suppose I have noticed some numerical shifting with Ultrachrome
inks when measuring the same target at different intervals the the
first few hours after printing (though my approach is likely much
less scientific), and yes the max delta E was probably around 1-1.5,
but the average delta E shift was much lower and the visual
difference was negligible...not to mention that if your profiling a
press, a color shift on press at this level can occur in the blink
of an eye ;-). Compared to what I've seen with HP dyes and an Epson
7000, the Ultrachrome inks are far superior in this regard.
