art techniques for eliminating banding

[Dawid Michalczyk]

Hi,

I'm looking for different techniques used to eliminate banding. The most
common ones are adding noise and rendering at higher bit depths for
gradients etc. What else do you recommend? I'm interested in general
ideas not specific instructions. Thanks.

Are the bands more in the reflections or from the surfaces? Some
things you might try.
Increase the brightness of the colors and decrease the brightness of
the scene.
Decrease the contrast of the bump map or change its height in the
renderer – try using a high pass filter on it.
Choose colors that are closer together.
Try lighting with a different environment map.
Blur your reflection map.
Increase the number of anti-aliasing samples.

Hi Dawid - I've never experienced banding in any print jobs, and I use
gradients all the time. I have heard of doing the gradients in
Photoshop though, then taking them into InDesign as an image.

I'm fairly sure you mean banding on the print - it is caused by the
printer. First do the necessary drill of cleaning and calibrating the
head, however rarely works to cure banding, so your next question might
be whether you should get a new and better printer or contract the
printing out.

To be more specific I'm talking about color banding (not bending) of
colors on screen (not in print). Here is a description of what banding
is with an example:

Color banding can often be a problem even with 32bit rendering. As I
wrote, I'm interested in the less common techniques used to eliminate it.

I've not experienced it myself in the past several years.

Loads of years, it seems it has more to do with screen-quality...and
that is a very hard thing to overcome.

I had a similar problem with an Illustrator image a couple of years ago,
where I had a series of blends and gradients between two fairly similar
golours. It looked OK on the screen but banded horribly when I printed
from Illustrator. Solved the problem by exporting a fairly high
resolution bitmap image and then printing that (was OK as a one-off
solution, but wouldn't want to do it every time). The problem was only
apparent when the end colours of the blend/gradient were _fairly_
similar in hue, saturation and/or value.
