Thanks for your answer Florian.
I can easly understand now why that patches look all dark: my profile starts
from L* 4 as darkest point...
I will write a mail to Keith asking him about his print test imge.
The step wedge is spread out so that the K steps are 5% apart. Maybe
recreating that wedge in some space with better perceptual properties
(Lab?) then transforming back to G2.2 could be an option.
The reason for the -no -ni -np parameters is that, according to an
expert that I have asked for some suggestions using colprof, this gives
better gradients. Withoud this 3 options he got steps in many gradients.
So I just followed his suggestion.
If you have never tried with that parameters try them and let me know
what do you think about it.
Interesting, thanks! I will definitely try it sometime.
