Banding In Gradients Created In Vector Programs
When artwork is created in a vector application such as Illustrator or CorelDraw, gradients can "sometimes" be a problem when separating the image in Photoshop. The reason is how these vector programs render gradients by using a mathematical equation, when compared to a gradient created in Photoshop which is a true raster gradient from the start. The video discusses the issue along with a quick fix on modifying gradients that contain banding to eliminate problems with mesh interference and moire.
To avoid nasty banding from the beginning, just draw or modify the vector art without gradient blends, or at least without a large dominant gradient that encompasses the entire piece of artwork. Then open the art using Photoshop and apply the larger gradient effects there.
