File with Bleeds
If a color, image or other part of your art touches the edge, you need to supply your file with a 1/8 inch bleed in addition to your file size. Supply your file at size plus 1/8 inch all the way around. If it is a business card your file size would be 3.75 inches by 2.25 inches. Half sheet flyer, 8.75 inches by 5.75 inches. The art should extend all the way to the edge of the file. All files should be supplied at 100% of the size at 300 dpi.
The best file type to supply is a PDF. Most programs can now save your art this way. This avoids any font problems that may arise, leading to incorrect print or delay of your job. Make sure you save your PDF as High Quality or Press Quality in the settings.
