Digital BW, The Print

Michael,

Which printer and inkset are you using?  I'm using the 2200 (currently 
with MIS Ultratones) and the tonal transitions are very smooth, with no 
apparent "roughness".  I was able to see highlight dots in some prints 
when using the UC inks, but just adding the UT light gray solved that 
problem and with the full UT inkset the tones are even better across 
the scale.  Are you using the "Adaptive Hybrid" dither pattern?  That 
one works fine for me at 1440x720 Highest Resolution.  Another dither 
pattern that looks very good is "EvenTone", but it does change the 
overall print tone and I would have to re-profile to correct the tone.
