How to Set-up Bleeds

What is bleed?

Bleed printing - Marsprinting

Bleed refers to a background color, graphic, or image that extends to the edge of the finished paper size and beyond. It's difficult for equipment to apply ink up to the cut edge of a sheet of paper. So an extra .125" (3mm) margin is typically added on each side of the design, enabling the background color, graphic, or image to extend past (i.e., "bleed off") the paper's final trim edge. This extra bleed area off the printed sheet. For example, a letterhead sheet that incorporates bleed in its design will be 8.75" x 11.25" before being trimmed finished size of 8.5" x 11".

In contrast, a piece with no bleed keeps all the printed elements a minimum of .125" (3mm) away from the edge of the paper on all four Nothing is printed to the finished edge of the paper.


Bleed vs. No Bleed

The illustration on the left shows a page printed with bleed, before trimming. When trimmed, the finished piece will have color or graphic extending to the finished, cut edge on all four sides.The illustration on the right shows a page designed without any bleed. When trimmed, finished piece will have an unprinted border on all four sides.


What is the trim edge?

A sheet with bleed is larger than its finished size. The "trim edge" refers to each edge of the sheet after it has been cut to its finished Any printed elements that extend beyond the trim edge will be cut off in the process of reducing the paper to its finished size.

What is the safety zone?

Safety Zone - Marsprinting

To avoid being trimmed off, text and other important matter must stay within a "safety zone" that is is a minimum of .125" (3mm) away from trim edge. Any design elements that extend beyond the safety zone risk being cut off in the process of trimming the paper to its finished For example, the safety zone for an 8.5" x 11" letterhead would be .125" smaller on each side, or 8.25" x 10.75".


Bleed Before and After Trimming

The illustration on the left shows a document designed with bleed (finished size plus an extra .125" (3mm) on each side). Because minor can occur when cutting the paper to its finished size, to avoid being trimmed off, text and other important matter must stay .125" (3mm) the trim edge (the "safety zone").

The illustration on the right shows the printed piece after trimming. Note the last "e" in "Example" has been cut in half because it extended the safety zone and into the trimming area. Some of the artwork has been cut off for the same reason. Any elements that extend past the zone risk being lost in the process of trimming the paper to its finished size.


How do I create bleed in my design?

To create bleed in your design, simply make sure the background color, graphic, or image you want it to bleed extends off the the final of the page by .125" (3mm).

If you are creating your file in an application such as Photoshop, you must make your document height and width dimensions .25" (6mm) larger your final trim size. For example, if the finished size is 8.5" x 11" then make your document 8.75" x11.25". Position guides that are .125" each edge. For design purposes, these guides will represent where the paper (and any of your design elements) will be cut.

Position any background color, graphic, or image that you want to bleed so they extended past your guides, all the way to the outside edge document. Remember, the extra .125" will be cut off after your piece is printed.
