Example files can be found here for each drinkware product.
No bleed is added as the entire content of the file is required to reproduce on the drinkware item without any additional scaling.
The only exception to this is the 11oz ceramic models, which as standard carry 2mm bleed on each edge of the file. The expectation is that the image runs off the top & bottom of the mug. Configurable file options are available to tailor file content to your specific workflow requirements, please ask your Partner Manager for further information.
