Hey Folks,
I have the answer to my problem. The MicroBanding, as it is called, is due my using the Epson 2200 at 1440x740 and not 2880x740. I have historically avoided 2880 because the printer moves slower than molasses (2 'l' s?)...however, we now have the answer to our problem.
Thanks all
James
PS Now, my second problem. I am starting to see metamerism in my prints...
