            At this point, let's explain the term "Bleed". The sheet 
            of paper that goes through the printing press is always larger than 
            the actual page size of the final book. The final printed sheet is 
            later folded and cut to size. This is the trim size. "Bleed" 
            refers to the process of extending any image that comes to the edge 
            of the trim and adding 1/8 inch more image. The reason for adding 
            "Bleed" is that a sheet of paper going through the printing 
            press can bounce slightly against the many "guides" used 
            to keep it going straight through the press. If you didn't incorporate 
            bleed, a sliver of white could show on some pieces when your cover 
            is finally folded and trimmed. Note that "Bleed" must be 
            added not only to your cover, but also to any pages where an image 
            goes right up to the trim.
