Digital BW, The Print

One additional point that might not have been mentioned in this thread is
that when a curve is applied to a file, the resulting image often prints
smoother if the file is 16 bit at the time of application, even if the file
was 8 bit and converted to 16 bit just before the application of the curve
and even if the file is converted back to 8 bit after the application of the
curve.
