Digital BW, The Print

Som people (like me) are expceptionally sensitive to slight color 
shifts in monchrome printing. Others don't notice it at all. I felt my 
ABW printing on EPSG paper was just ever so slightly blue green so I 
used the toning wheel feature with settings 2H and -1v to move the tone 
just a bit toward the magenta and it looks neutral to me. You might try 
these very subtle toning wheel moves and see if it solves 
your "problem". It did for me. My wife who is an artist thinks I am 
nuts, but I suspect we all have very different sensitivities to this 
phenomenon of red-green sensitivity.
