art techniques for eliminating banding
Date:Thu, 18 Dec 2008 13:00:35 +0100
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. Dawid Michalczyk -- _DMEW_ Abstract art http://www.art.eonworks.com/gallery/abstract/abstract_gallery_1.html

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 =96 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. --- CL8'N.

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.

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

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).
