Getting Rid of Banding-
Setting the DPI and Speed
Banding is so annoying, especially after printing a 24 x 36 or larger. We've found that it occurs most visibly in prints that have large, dark, monochromatic regions. Meaning a large area of pure black, or dark blue, etc.
We've found two ways to help get rid of banding: Change the dpi or the print speed, or both.
Changing the DPI
This technique never ceases to surprise us. In some instances, raising the dpi will remove banding, while in other cases, lowering it will get rid the print of this flaw.
We have a canvas material that seems to band no matter what! We tried raising the dpi from 1440 to 2880, to no avail, then one day I set it to 720 dpi as a fluke accident, and the banding was gone. So we can't give you a specific setting, but if you have banding, play with the dpi.
Warning: changing the dpi changes the color output. If you decide to change the dpi, first make a small proof to check the color before you print the larger image.
Changing the Speed
This is more often the culprit to banding than the dpi. This one, however, does have a general rule to live by: Single speed (high speed off, or unchecked) does result in less banding. In fact, we've ended up saving money and time by never printing in high speed when doing the final print. It may take twice as long, but if the print has banding, it would take twice as long anyway!! Plus, you waste paper and ink as well.
If you are printing 8 x 10 or smaller, you are usually safe to print high speed without any repercussions.
