Live Area, Trim, and Bleed:
If you are supplying artwork that runs off the page, you need to create a "bleed" so no white will show on the final print. Usually we refer to three margins on a page:
Most programs have an option to add bleeds to your document (usually in document set-up), but you may simply make your document slightly larger than the trimmed size (e.g. 1/8" or 1/4" all around).
Printer's Marks:
We do not require any Printers marks.
