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).
