Digital BW, The Print

I think you are totally wasting your time and the printers capability by trying to print out of 
one channel. It just seems silly and retrograde to me.  I've done it for years with the 10K 
which has a  superior heads and it is very limiting, If you would just do as Tyler suggested 
and buy QTR for Ultracrome you will be MUCH happier. I produce totally neutral and totally 
metamerism free prints every week this way. Not Piezzotone, but very very good.  If you 
are looking for an Iflord Ilfobrome hue try Ultrachrome with Matte black and a curve 
setting of - Warm - 60/ Cool -40, or for a more neutral result - Cool -70 Warm- 30. This 
is with Innova or Hahnemuhle Rag. The Innova FibaPrint paper works very well with similar 
settings.
