Digital BW, The Print

In an answer to my request for help, John Dean sent me the following:

"Finally there is a way to go into the 10K printer menu and slow your 
printer down to what I believe is called 8 pass printing that 
improves quality (4 pass is the standard but not as precise). I do 
this on mine as a standard procedure. I had some banding initially on 
the slower print setting. But I'm using SP with Smooth Diffusion 
dither. That setting did it for me."

I am using StudioPrint as he is and, following his suggestion, I 
looked for the commands that would allow me to change the speed of 
the head. I found it in the "Device Controls" tab where there are 
choices concerned with the pass and dot size. Unbeknownst to me, I 
was using "standard 1 [4 pass| Variable small]". There were other 
choices, one of which was 4 Pass Normal. I changed to that one and my 
banding disappeared! The print, however, darkened about 20% so I will 
have to re-linearize to get more correct ink lay down.

There was no setting choices that would allow an 8 pass mode. I am 
using smooth diffusion as a dither pattern.
Thank you very much, John! I don't know if the choice that I made is 
the best one but it did instantly eliminate my banding problems. I 
will look at the other choices and see what they might deliver.
