For printers, bleed is what we call the images and graphics that go beyond the edge of page. In other words, the bleed area is the extra space on the edges to be trimmed off. Printers will print your file on large sheets and cut your document down to the final size. The cutting blade on every machine has a small amount of movement each time it cuts. This is where the bleed area comes in.
Printers need a minimum of 1/8” of extra graphics extending beyond the edges of the document. Because each edge of your document needs to include 1/8” bleed on every side, be sure to add 1/4” to your document’s height and width. Doing this will ensure plenty of room for us to cut your final print to the perfect size.
