ColorThink is calculating the TVI based on XYZ colorimetry while
Measure Tool is going to the spectral data and converting to Status T
(or whatever) and then computing TVI from there. Both use Murray-
Davies, they're just coming at it from two different metrics. Measure
Tool will agree more closely with your spectro-densitometer.
Let me guess...looking at the TVI in ColorThink, the yellow TVI was
higher than you expected while the cyan TVI was a bit lower?

Here's what I don't understand, when I compare the Measure Tool
measurement data dot gain to the ICC profile dot gain in ColorThink
Pro, the curves are nearly identical, except that they are complete
mirrors of each other. 0=100, 25=75, 75=25, 100=0.
Can anyone help with what I'm not understanding or what I'm seeing?
