Which safety margin do I need to observe?
Position critical graphic and text elements at least 0.2 inch away from the final trim size unless otherwise specified.
If you include the bleed, these elements should hence keep a distance of at least 0.24 inch from the edge of the print file.
Please bear in mind that wire-O bound products such as catalogs may require bigger safety margins.
For more information, see the data sheet of the product in question.
Important graphic and textual information which must not be cut should be located at least 0.2 inch from the final format if not specified otherwise.
