Digital BW, The Print

Hi everyone

Read alot about BO printing on this forum so decided to have a go. 
I've compared side by side my BO prints with prints using all the 
inks and I must admit I'm rather impressed with the BO prints. The BO 
prints have better dmax, and have something about them. Digital Tri-X 
is a good description. However I noticed that in the shadow areas 
there is fine banding. This spoils the print for me. I'm using a 1160 
with MIS UT inks and eboni black printing on EAM paper. I have 
checked the printer head alignment and nozzle check is perfect. Is 
there a way to reduce banding or is this a product of using a printer 
that can only print at 1440 dpi.
