QTR, 1800 and banding (was Re: QTR and R800)

2005-06-14 by s_m_fletcher

Dear Roy

Some more feedback on a great product: I've also downloaded QTR to 
try with my R800.  I'm getting banding regardless of the settings I 
use (i.e. at all dpi settings and using the different dither patterns 
and different curves/mixes of curves).  The 2880 dpi + normal dither 
setting with a 50% cool/black curve mix is currently the smoothest I 
can get - but not quite perfect.  The next best is the 1440x1440 + 
normal dither + black curve only.  If I can get rid of the banding, 
QTR will be a great solution: the B/W print tones are just what I 
want.  (NB: I have performed all the usual cleaning/alignment cycles, 
and colour prints through the Epson driver have no banding).

I have previously printed B/W using MIS inks with Paul Roark's curves 
in a 1290.  These have worked really well, when they worked - I have 
had recurrent banding problems with the old VM inks and the latest UT 
inks, which can be frustrating to say the least.

Many thanks 

Stephen
