Jon, I have to agree completely with you. I often, when working with nudes, will use PhotoRag with the Wells River profile. It just works a little better at times. How do you go about adjusting local contrast? With a mask and the curves? David Myers

I run a digital imaging studio and print for a lot of different photographers so I see more varied files than most. I have tested several of the popular inks and workflows, currently using the MIS FS and the cone driver. The "posterizing" and sometimes "edge breaks" are most evident in portraits and nudes but do occur in other types of images. My experience leads me to believe one of the basic problems with gray ink printing is that at the precise tonallity where the different gray inks "cross over"undesireable things can happen. The choice of papers does affect how this effect occurs, because of how each paper responds to different coverage. I have had some sucess curing this problem by mismatching profiles and their papers. Otherwise I alter the local contrast of the file where the tonal problem is manifested. If one has not seen this ocuring, they are either extremely lucky or they are simply not viewing their prints objectively enough. Broken up histograms have almost no bearing on this "posterization" that I'm specifically referencing. J.Z.
