Digital BW, The Print

hi all,  i am using a 1280 with the u2 inkset and i can print fine
either directly printing to the printer or applying curves and then
printing, it all looks fine. when i print using qtr, i get banding
across the entire image. the effect  looks like to be 4mm in width and
a different shade of what i am printing.


i am using a 1280 with u2 inkset and the yellow position loaded with
glop. and printing using the following curves in
ut2-EpermLuster-netral-3 @ 100.

resolution: 1440: super
speed faster
dither algorithm: ordered
