Graeme, Martin,
Thanks for your patience.
I don't want to be a hassle but, even if your explanations are very clear,
I'm getting a little bit confused...

With xicclu -g -fif -ir -kp 0 .1 1 .95 .25 -l330 -L95 FOGRA39.icc I get a
new image1 where I can see that the black shape is changing toward the shape
I want but I'm not able to "move" the enpo further toward the 1 value as I
think would be appropriate to emulate the black shape in image2 ( xicclu -fb
-g -ir ISOcoated.icc).
