How to remove strange banding from PNG export with radial gradient
I'm using Illustrator CC 2014 and have a radial gradient that looks smooth in edit, but gets really weird bands when I export or Save to Web (any format, all settings).
Here's how it looks in Illustrators artboard (just the top):
And here's how it looks after export!?
Notice the two light bands? How do I stop this?
You can also try adding a grain on top of the gradient- it will kind of simulate PS's gradient dither. Effects > Texture > Grain. It's a raster effect so not optimal, but it should help.
