I recently got a 2015 i1 Pro 2 with very little use, and have been trying unsuccessfully to get usable profiles with several matte papers.
For comparison, I have profiles from the OEM and custom profiles done with an iSis and i1 Profiler. I also made some profiles with an i1 Studio about a year ago, and though I no longer have those, all three of these sources produces very similar profiles in gamut, smoothness of transitions, etc.
The i1 Pro 2 matches the gamut size, and is perhaps better in transitions, but the colours are off: in particular the saturated blues are shifted toward violet, and the very saturated yellows and oranges lose detail. These characteristics are consistent with every paper I have tried, and whatever patch count.
I'm using a Macbook, so I unfortunately can't use Gamutvision for comparisons, but using Copra a comparison of the linear graph shows a dogleg in the blues, again consistent in every profile, and unlike the OEM/Custom profiles. And a comparison of the gamuts shows that the gamut has a very similar shape to the custom iSis profiles, but the whole thing seems to be shifted away from the blues and the darks, and toward the yellows.
At this point I have run through a lot of paper, and run out of ideas. I wonder if I am missing something basic in Argyll, or whether the i1 Pro 2 measurements are off. I've tried a lot of variations (including specifying the default values for illuminant, etc), but I am mostly using these commands for targen and colprof:
targen -v -d2 -G -e8 -B8 -g128 -f2025 outputFile
colprof -v -qh -sAdobeRGB1998.icc -cmt -dpp inputFile
Does anyone have any suggestions, or ideas about what is going on?
I'm attaching images of the line graph from Copra, and the gamut comparison - the wire frame is the iSis profile (again, this is virtually identical to the OEM profile) and the solid colours are the i1Pro2.
