"Bleed" is a printing term used to indicate the area with a background image that will be trimmed off after the file is printed and cut to final size. Since the bleed area will be trimmed, there should be no text or other important information in the bleed area. Projects that make use of image bleed should extend any bleeding background and/or images 1/8-inch over the final paper trim edge. You should keep all other text and graphics at least 1/4-inch' away from the final edge that will be cut. This will make your work look professional and that no images or type will me missing in the final product. When working in portable document format (PDF) in Adobe Acrobat, you can add a bleed in just four steps.
