CUSTOM GRAPHICS: In order to print custom graphics on your cover, all graphics must be uploaded below in Illustrator/Vector format (preferred) or a high-resolution, layered, Photoshop file (20" wide). Graphics that do not meet these requirements may incur additional processing fees. Custom graphics may take two to three weeks to process. If you have any questions, please call 1-877-99-COVER before placing an order. Creative art services are available if you need help.
