When using perforations, margins are crucial to the artwork setup. In the example shown below, all 4 sides bleed (ink goes to edges) and you simply follow the dimensions shown. The overall canvas size is 6.75 x 3.75. If your artwork does not bleed, the overall canvas size is 6.5 x 3.5. All other guidelines for preparing artwork, see Specifications.
