7600 banding problem solved

2004-08-30 by Steven Karafyllakis

Hi All;

After all my grousing about this dither-banding problem, I thought I 
should post the solution I arrived at, with some greatly appreciated 
help from Michael Askew. I'm sure this has been posted before, but 
it bears repeating-I can't be the only one that missed it the first 
three times (can I?).

The head alignment (Uni-directional and Bi-directional) did not 
help. Mind you, I got better resolution, and got rid of most of the 
color fringing, but the banding was still there. On Michael's 
advice, I turned off first the "finest detail" option, and then the 
Bi-directional. Turning off "finest detail" made a huge difference-
80% of the banding went away. Turning off Bi-directional (aka high-
speed)got rid of the rest of it, and cleaned up the fine detail some 
more. Never did think much of that HI-speed option, every printer 
I've ever owned has done better without it. Now if I can just 
translate this to QTR-ese, I'll be a happy camper, and I can do 
something else with the 7500-has anyone perfected that coating-fluid 
in-the-printer process yet?
