This article explains how to completely cover the printed page with an image without any unwanted white edges.
Correctly designed bleed
A correctly-designed bleed or full bleed layout means the image will print all the way to the edge of the page without leaving a white margin.
Below is an example of a full-bleed layout with the image touching the page edge/bleed edge.
- This was designed in BookWright so the bleed edge is the outer edge of the pink shaded area.
- The red dotted line is the estimated trim line.
- Regardless of the program you use to make your book, bleeds must be designed beyond the trim line and reach the outer page edge/bleed edge.
Below is a close-up of the bleed layout. Notice how the image runs past the red dotted trim line and all the way to the page edge. This is good.
Incorrectly designed bleed
An incorrectly designed bleed might look like this. The image was not placed all the way to the edge so there's a margin (white line) visible.
The printed book might look like this, with a thin (and unwanted) white edge. The trim line is only an estimate so bleeds must go past the trim line and all the way to the page edge to avoid this problem. You might want to read up on designing bleeds in our different creation tools.
