Hi,
I create a profile after calibration..
I'm not sure what you mean by that. Calibration using
what mechanism ?
(Calibration is not the same as Profiling !)
After new colprof command and applycal to the profile.
But the curves are not changed..
If your graph was the result of
xicclu -g profile.icc
then this is to be expected, since you are plotting
the printer RGB's that creates neutral colors (a* = b* = 0).
i.e. you are demonstrating that the printers native
R=G=B grey is not neutral, and what RGB values are
needed to print neutral colors. This behavior is what
the device profile captures.
The only way this would change is if something changes
the way the printer is working - i.e. different paper,
inks, printing mode, calibration etc.
