Often, while using Fountain Fills, some colors end up with undesirable color blends (color banding). With CorelDRAW X7, you can now apply smoothing to reduce the banding and give a smooth blend to Fountain Fills. See Figure (A) for reference. Smoothing can be enabled from within Edit Fill dialog box. See Figure (B) with the Smooth button highlighted.
