Digital BW, The Print

Michael, I'm using a 1280.  I am flatbed scanning b&w prints in RGB reflective. After a minor amount of burning, dodging etc, contrast etc.  I am desaturating, then in color balance I will add + 2 or 3 midtone magenta, and sometimes +1 or 2 to the shadow of magenta.  I am set on Heavyweight matte, 1440, in the advanced mode, "color controls" all set at zero. Profile is Adobe RGB.
I'm printing on LPM or SEV.
