When incorporating gradients into your design, for example applying a vignette, it is important to think of the printing method to be used. The Flexo printing method tends to leave an abrupt edge when handling gradients if they fade to a zero value (white) in the middle of the label. It is better to carry the a very fine screen dot all the way to the edge of the label when using the flexo print method. Otherwise, digital printing may be a better solution for this design element
