How should I set up my bleed?

Bleed
Please include an 1/8″ (or .125″ extra on each side) bleed on all sides. For instance, a square business card is 2.5” x 2.5”, your canvas size needs to be 2.625″ x 2.625″. 1/8″ will be cut off during trimming, leaving you with a 2.5″ x 2.5″ square business card.
Safety
The bleed for all cards is 1/8” (or 0.125″) on all sides. What this means is that there is an accepted variance for 1/8” to be cut off on either side of the cut-line. We recommend that design of the card extends all the way out to the trim line, so that the design is consistent throughout the whole card. Also, the text needs to be kept at least 1/8” inside the safe-line to ensure it does not get cut off during trimming.
What resolution should my file be?
Why does my business card crack around the edges?
This usually happens on a small amount of cards in the run. To prevent this, use lighter colors or if you must use dark colors, use as little ink as possible.
