Digital BW, The Print

Steve,

I seem to be getting results that are different from what you are  
seeing.  Below is a comparison of density and Lab-L, with and without  
icc profile.  Printed with 2400, MK, Hahnemuhle PR BW, using default  
ABW neutral-darker settings and 2880 dpi (RPM).  QTR gray lab working  
space.  Create-icc (2.3.2) used to make the icc profile form the new  
step-wedge (10, 5, 1 % steps), but standard 21 step used for print  
with the icc applied.  Note that without the icc there is some  
compression in the shadow region that is improved with the icc.
