Okay! Nevermind the last one, i learned about the -r command!
So, i fixed the issue with the last row, now the peak error is only 7. And
the generated profile looks like it's an actual printer profile.
Right now i don't have access to my 7800, but i was comparing my profile
with the GRACoL one, and mine is around a third of the gamut volume of the
gracol one. Is this the best i can get? Am i maybe doing things wrong that
i am getting such a small space?
Thanks again!
