In printing terminology, the bleed is the extra margin on a print product that is meant to be trimmed off when the product is trimmed to its final size. Bleed basically means that the color and graphics on a product “bleed off the page” to ensure continuity of the color to the edge of your product.
A full bleed is required for all print-ready files. For the correct bleed for your product, please view the list below. For example, most business cards have a 0.1″ bleed, so a 2″ x 3.5″ business card without round corners will have a bleed size of 2.1″ x 3.6″.
