Print your mirrored design on sublimation paper with sublimation ink.

Align and tape your design onto the glossy side of the coaster.

Press at 385°F (195°C) for 60 seconds with medium pressure.

Peel immediately after pressing and let cool flat.

✨ Pro Tip: Use butcher paper above and below the coaster during pressing to prevent any stray ink from staining your press.

Can I sublimate directly onto these coasters?
Yes! The glossy white coating is made specifically for sublimation transfers—just print, press, and peel.

Are these waterproof?
They resist moisture from cups and glasses, but are not designed for soaking or dishwasher use.

Can I use HTV or vinyl instead of sublimation?
Yes, but sublimation provides the most durable and professional finish. Permanent vinyl can work for non-wash applications.

Are these single-sided or double-sided?
They’re sublimation-coated on one side; the back is a natural hardboard finish.
