If you have ever dealt with a word processing application you are familiar with the document page. However, desktop publishing applications differ from word processing applications as they also have a pasteboard (among other differences). The pasteboard is that white area around the page where you can put objects that you might need while you design, but that will not be printed.

You then have the margins within your document's page. Now we are getting to the harsh part ... the bleed and slug. Jokes aside, here are the definitions of these two terms and an explanation of what they do:

  1. Bleed: "When any image or element on a page touches the edge of the page, extending beyond the trim edge, leaving no margin it is said to bleed. It may bleed or extend off one or more sides." Bleed Illustrated:

  2. Slug: "Usually non-printing Information (such as a title and date) used to identify a document" Yes there was a time where also I had to learn what a slug was. I wish I was a born DTPer ... Read Slug - Not a Bug (inspired by a inquiry I made in the forum).

In the illustration I have set the bleed to 3 mm and I have set the slug at the bottom of the document. But you can change these settings or not have any bleeds or slug at all. If you are printing to your desktop printer you do not need any bleed allowance. I will explain how to set bleed and slug in the next section.
