How to print a sublimation mug
Print the transfer
Measure the printable band on a blank. Keep lettering and faces away from the rim, base and handle where the press may make less contact. Mirror the artwork once and print with compatible sublimation ink and paper.
Wrap and tape
Wipe the cold mug with a clean, lint-free cloth. Wrap the paper with the printed side against the dry ceramic. Secure it with heat-resistant tape so the paper stays flat when the press closes.
Press a sample
Follow your equipment instructions for coated ceramic. Published starting points for this mug include 180°C for 180 seconds at medium pressure with a cold peel, and 180–200°C for 150 seconds. Use these to plan a test. Presses differ in how they measure heat and when the timer starts.
Cool and inspect
Use heat-resistant gloves and a heat-safe surface. Follow the press and transfer instructions for cooling and peeling. Check small text, edge definition and colour against the proof before pressing the whole batch.
