Indeed we can! We use a premium clay-coated white corrugated material called Dreamcoat™, which creates a gorgeous satin sheen to the ink when printed.
With the Dreamcoat™ finish, the unprinted areas are a brighter white. The deeper the ink color you use, the more shimmer and contrast you'll see, so this is best selected for designs with deep colors over significant portions of the box.
