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.
