I'm working with a gradient in Illustrator, but there is banding in gradient. I'm trying to increase the color depth, but I can't find the color depth setting.
If there are any other methods to remove banding, I'm open to those ideas too.
Interesting point. But you can not.
In the end, Normally Illustrator, or most vector programs for that matter only works with 256 levels of values. Even when working CMYK values, that are represented on a 0-100 scale, are using 256 values.
But the thing is it does not matter that you use for example a 16 bit per channel image. The values are going to be translated to a 256 depth on the output.
