Gradient Resolution Problem in Illustrator CS6?

Hi friends, I've encountered a problem when using simple gradients in Illustrator CS6 v v16.0 on the Creative Cloud. My gradients are not smooth, you can see vertical/horizontal delineations in color when in linear mode, and circular delineations when in radial mode. This seemed strange to me since this is vector based. The attached picture is an example of this problem, it's 18x24 at 300dpi. It also persists when I export/save the image. This problem is also present in Photoshop.

Any thoughts?

    It's called banding. Read up on it - the math reasons behind it, why it may merely be a display artifact, how to minimize it and so on.

    audioverb,

     

    I can duplicate this gradient at the same resolution in Photoshop/Illustrator CS5 on my other desktop, and it comes out smooth.

     

    You may get (quite/rather) different appearances on different monitors.
