A printed one side folder customizes the covers and the pockets which fold in from the front. You can design design the entire outside of your folder. The inside of your folder will stay white.
When you layout your artwork it is important to remember that your design includes the pockets since they fold in and are therefore part of the “outside” of your folder. So even after opening your folder, you will still be able to see your branding.
The one side print is the most cost effective way to create a custom printed pocket folder.
