While commercial trimming equipment is highly accurate, environmental and mechanical conditions beyond our control can affect its precision. As a result, the actual edge of a trimmed piece can vary by as much as 1/16″ from the planned edge of the page. As printers, we use a “bleed” area to compensate for this variation.
If your printed piece calls for a border along its edge, you will need to extend that border 1/8″ beyond the outside cut line, in order to ensure that it prints properly. Otherwise, you might run into issues when the piece is cut to its finished size.
