Full bleed is printing from edge to edge of a document. Full bleed requires a minimum of 1/8" (0.125") on all sides of the artwork to ensure accurate cutting (e.g., artwork for a 5"x8" postcard should extend to 5.25" x 8.25"). If your image has a white border on all four sides, bleeds are recommended but not required. If your image is not white on all four sides, you must include bleeds in print-ready files.
To prevent an unwanted white border from showing at the edge of your document, be sure to extend any background colors or design elements all the way to the edge. Please use the provided guideline templates as much as possible to setup artwork.
