Digital BW, The Print

Mike -- I've had some problems with posterization of blacks with the Brandin curves with MIS quadtones. In fact, I've started to ensure that there are no 100% blacks in my prints -- I make sure the darkest black is 98%, and the prints come out much better. I'm sure I'm losing some depths in the blacks though, which bothers me. The other shades seem fine to me.

Also, oddly enough, the regions of pure black sometimes appear LIGHTER than areas that are primarily 75%. Maybe I'm not really understanding how the curves worked. I'd think that I got the lines crossed on my CFS, but I was incredibly careful to make sure that I got the right inks in the right order, checking NUMEROUS times while setting up, labelling everything carefully, etc.

Overall, however, I still prefer the Brandin Curves to the Nevin transfer functions, since I really like the dotless prints...the Nevin dots seemed very apparent to me when I tried that workflow.

later,
