Images should be 300 dpi or higher - PNG/JPEG files with less than 300 dpi will be rejected.
Your artwork should include a 1/8" border around the final trim size. This means your final file size will be a total of 0.25" larger than your expected printed piece (ie, a 4"x6" postcard should be submitted as 4.25"x6.25"). There is no need to include crop marks in your submitted content.
Include a safe zone – make sure no critical elements are within 1/8" from the edge of the final size.
Do not include any additional postage marks or indicia.
File sizes should be no larger than 5MB.

Submitted images must have the same length to width ratio as the chosen product. Images will not be cropped or stretched by the API.
