I try to build rgb profile that is equivalent to other cmyk profile. I
found that fakeCMY and excel do the trick (I found comment TTBD i fakecmy
source code and I tweaked resulting ti3 to be rgb). But I try understand
what fakeCMY is doing. It is possible to recreate effect of fakeCMY
manually with other tools like icclu/xicclu or fakeread? Source code in C
is too coplex for me and I can't figure it out.
Is it possible to make gamut file (and visualisation) of n-color profile
with argylcms? I checked iccgamut and it is not working with n-color
profiles. It is a feature or bug? Maybe someone knows other tool (open
source or free) to visualise gamuts including n-color profiles?
