Digital BW, The Print

I guess my point was that the 2200 seems to be the best candidate for 
B&W with Ultracrome inks. Even if BO printing were allowed with 
either the 800 or 1800 don't we still need the light gray. I would 
like to think that the Ultracrome B&W prints made on the 2200, 4000, 
7600, 9600, etc. Would be hard to tell from those made with a 
dedicated Quad tone ink setup, or at least, from a setup which 
contails sepia and blue toner. Is one More archival than another. Is 
one tonely superior or would it be hard to tell.
