Digital BW, The Print

Hi Jamie... I've been making measuring stepwedges printed with
different ABW settings and also modifying IJC profiles (and measuring
the stepwedges) to try to make neutral K3 prints.  Keeping the A and B
values "vertical," i.e., with a relatively constant value from 0 to
100, makes a print that is definitely not neutral looking.  Also,
getting the values to go quickly from paper white to 0, and then
keeping the values at 0 until the last few steps, did not produce
neutral looking prints.  I think Paul has stated it pretty accurately
in his previous post.
