Digital BW, The Print

Olivier-

It wasn't clear to me if you were actually asking whether to use 
perceptual or relative with the Create ICC profiles letting PS manage 
color.  The answer is, use perceptual.  I have never found that this 
gives a very convincing soft proof (the weakness of the black is 
exaggerated in my soft proof setup), but it gives a very convincing 
print and one learns to use the soft proof.
