I use Gamutvision. I can forward my profile to you for comparison in Colorthink.

Excuse my lack of knowledge here, but why would gamut volume be calculated "differently" by different software? Isn't it pretty straight forward math ... plot the points and see how much "volume" is contained within the points?
If this isn't the case, then gamut volume begins to lose meaning as a comparative measuring tool with profiles. Requiring everyone to standardize on a software package to obtain meaningful measuring data doesn't seem logical. A profile is a profile and profile evaluation software should apply the standard - it sounds logical to this non-engineer's brain anyway.
(sorry to get of topic ... but I've sort of dragged this thread off topic anyway )
Anyway, after printing a new test chart and remeasuring I now feel I have a very good profile for Kodak Prof. Glossy paper on the 6100, and soon my other papers as well. Fixing the problem mentioned yesterday shows a gamut volume of 729,592, slightly larger than the previous one. The sharp inverted spot is gone and that area is now included in the gamut of the profile. I guess I'll measure the original test chart again to see if is a problem in reading the data or a problem in the chart (just curious).
The profiles are identical except for the one problem area (as they should be), so as far as comparing gamut vs the 11880, nothing has changed. The 11880 has an overall larger gamu - slight in some areas, a little more in others (notably the yellows). The 6100 extends outside the 11880 in the dark blue/magentas, a little bit in the saturated red, and a very slight amount in the green- pretty much in those areas the primary inks can make a difference.
Meaning? Probably nothing ... both are great printers, have great gamuts and deliver amazing results - rich saturated colors, delicate and beautiful gradations.
If anyone is interested, I did a little movie in ColorThink that gives you an idea of what differences there are. find it at

Again,I appreciate what I've learned here.
