Dithering: which method produces the least banding issues

Dithering: which method produces the least banding issues

2007-07-22 by pglombick

I am experiencing horizontal banding problems in the upper and lower 2-
4 cm of prints. 

Printer: R300
Paper: Epson Enhanced Matte/Hahnemuehle Museum Etching
Ink: Piezo K6
Windows XP
QTRgui 2.5.1.8
Resolution: 2880 dpi
Speed: Unidirectional
Dithering: Ordered

The banding is confined to the upper and lower portions of the image, 
which I find strange. I do not believe it to be the result of clogging, 
head alignment, etc.

Any suggestions?

Thank you.

Paul
