QTR-Quadtone RIP

Tom,

I guess my attempted description could be taken either way. The 
banding I'm seeing is actually in the same direction as the print 
head motion. If I look at 1 of the small squares on the Ink pattern 
page (produced in calibration mode) I can see approx; 7 dark lines 
where the ink has laid down heavier, or about 7 light lines where 
the ink hasn't been laid down heavy enough, guess it depends on 
opinion.

I wish it was the pizza wheels, thanks for your input Tom,

Jamie
