Digital BW, The Print

Frank,

This is what everyone here means when they talk about posterizaton. It is a
loss of tones in some part of the image giving it a pasty look.

First off check the Histogram of your image with the RGB curve off and then
on. If it has lots of gaps and spikes than some data has been lost as a
result of making adjustments to the image or the applications of the curve
has caused too much data loss.

Solutions may be to try a different curve or combination of curves, go back
to the original 16-bit scan and do your large adjustments there before
dropping to 8-bit, do all of your adjustments in 16-bit mode or (long shot)
try color selecting the tonal range that is flat and apply a curve to
increase contrast.
