What to prepare
- Design file: PNG, preferably on a white or transparent background, in good resolution.
- Simple designs transfer better: a logo, short lettering, graphics in 2 or 3 colors.
- Decide where the print goes: chest, back, the whole front, the side of the mug.
If you do not have a design yet: logo with AI.

Limitations
- Small text and details can get distorted. Check every mockup by comparing it with the original.
- The garment and print color on the mockup must match what the buyer receives.
- The print size and placement too: if the mockup shows the print across the whole chest but you print a small one, that misleads the buyer.
- Other people’s logos, characters and brand lettering on a product for sale are not allowed: brands, logos and characters in AI.
For marketplaces
Mockups are handy in product listings, but it is better to make the first photo a real photo of the product or a sample, if you have one. More: product cards with AI, marketplace product images.
