Do I need to upload a file for a blank or solid-color side of a two-sided print?

If one side of a double-sided piece is meant to be blank or a single flat color, you do not have to build and upload a full design file for that side.

• Leave a clear note on your order describing the second side, for example back side blank or back side solid black.
• Or upload a simple placeholder file that shows the intended solid color so there is no guesswork.
• Specify the exact color as a Pantone or CMYK build if the side needs a particular tone rather than plain white.
• Reach 4OVER4 support before you approve if you are unsure, so the setup is confirmed before anything prints.
