Bleed is the amount of artwork that falls outside of the printing bounding box, or outside the crop marks and trim marks. You can include bleed in your artwork as a margin of error, to ensure that the ink extends all the way to the edge of the page after the page is trimmed or to ensure that a graphic can be stripped into a keyline in a document.

You can specify the extent of the bleed and add a variety of printer’s marks to the file.
