"Bleed" is a publishing industry term used to define printing that goes beyond the edge of where the sheet will be trimmed. The “bleed” is the area trimmed off. For example, if you have pages with images that extend all the way to the edge of the page, you would need to run the image to the “full bleed” edge of the page. The bleed portion of the image would be trimmed, ensuring the live area is visible with no white border (unprinted paper) around the edges. Most of our files require 0.125” bleed on each edge of the document, adding 0.25” to the total height and width.
