If you want the gradient affect, turn off the Vector and/or Bitbap ColorSure panel (take the check mark out of the box on the print properties screen). That way, ColorSure doesn't try to mimic the gradient in steps with ColorSure Palette colors. The other way is to convert your image to a bitmap and once again, take the check mark out of the Bitmap ColorSure panel box. This worked for me and solved many frustrations with the striped look of gradient fills.
