The portion of an image, line, or color that extends beyond the final page size.

Bleed is necessary for when you want images, lines or colors to go to the edge of the finished page. For example, a 6 x 9" page is created larger (6.25 x 9.25") and is centered .125"(1/8") around the finished page size. See the image below.

When creating a document with bleed keep in mind that important art and text should be .25"(1/4") from the edge of the finished page size. This will allow for trim variance as well as bleed. The variance is shown below from the blue dotted line to the orange dotted line.
