Printer is a Canon Pro-1000
The Paper is from Red River Palo Duro Softgloss Rag (no oba, acid-free)
(I try not to use any paper with OBA as much as possible)
The instrument is a I1 Studio (ColorMunki)
I did a profile for the same printer and instrument but another Red
River Paper, Palo Duro Etching and I don't remember the error level but
at least the gamut is smooth, no wrinkles or similar the SGR profile
give me.
Hope this help, if needed I can provide links to image of the gamut.
Thanks,
Yves

The errors you report are at least ten fold greater than I have ever seen using
Argyll. It would be useful to know what printer and paper(s) you are
profiling. I do know that some textured matte papers can give higher errors
because of light scattering but in my experience it's usually less than 5%
compared to smoother surface papers. I don't know if OBA containing papers
would cause such errors as I do not print on those.

I use a couple of programs to view the gamut of a profile and I made my first
one using Argyll tools and it showed a smooth surface, very nice.
I tried to make another one and now the profile is most likely useless, the
gamut is not smooth as most I've seen, I have remeasured the patch just in case
but same results.
I guess the problem is with the target print themselves but is there a way to
verify before wasting a few sheets?
Also I see what seems to be relatively large errors is this normal? What should
I expect?
These are the values I get from my last attempt.
"Profile check complete, peak err = 24.124852, avg err = 4.267474, RMS =
5.726972"
