Preparing Your Files

If you have not already done so, please review our guide to Preparing Your Files for acceptable file types and file specifications. This page covers important terminology and file setup, including:

  • Bleeds, inner margins and trim size
  • CMYK color and color matching standards
  • Image resolution and dpi
  • Embedded fonts and linked files
  • Copyrighted images and other content
  • PDF and printed proofs

Following these basic design specifications will ensure that your order moves through production without delay, that your order prints as you intend, and that your postcard meets the necessary USPS guidelines for mailing.

US Postal Service Regulations for Mailing

If you are using our mailing services, the United States Postal Service requires that certain areas of the address side of the postcard be left white for addressing, postage, and bar coding. This includes background color, text, and any photos/images. The dimensions and exclusions vary based on the postcard size, so please adhere to the exclusion areas defined in the layouts below.

If you are choosing Print + Address service, and plan to mail your cards yourself, the only exclusion you will need to follow is for the addressing area. To find out more about USPS requirements for your mailing, we recommend visiting your local post office or the official US Postal Service Web site.
