Bleed is the extension of imagery beyond the edge of the printed page. Generally printing is done on oversize sheets and therefore this 'bleed' is printed. The sheets are then cut to the finished size and this ensures that the colour will extend to the edge of the page when cut in a stack.
The use of bleed then eliminates any position variably from sheet to sheet during the print process. We like to have 2 - 3 mm of bleed around an image
For the same reasons as bleed is required we prefer to allow a minimum of 3 mm internally from the finished edge for all text and important parts of the imagery.
