Document Bleed
8th August 2009
The term “bleed” is used for all objects overlapping the border of your document:
Let’s say you are working on a brochure with images that butt right up against the side of your pages. The trick is to place the element so that it goes over the border, where the document will be cropped after printing.
You will be supplying the printer with a document a little larger than the finished document will be. After the brochure is printed it will be cropped to its correct size.
Important: The “bleed” in your document also allows the cropping some room for error as the paper itself may expand or contract, the cropping machine (Guillotine) could be set up incorrectly or the operator working on the brochure may occasionally make a mistake. If you hadn’t allowed for “bleed” then the images wouldn’t be neatly aligned with the side of your printed document
As a general rule we require 3mm of bleed to all edges.
