- Preheat and Mount Item: Place the appropriate fixture (e.g., phone case fixture) into the machine. Allow the machine to preheat. Once preheated, mount your item (e.g., phone case) onto the fixture.
- Position Sublimation Film: Place the printed sublimation film onto the item. Ensure the matte side of the film is facing the print side of the item. Secure with heat-resistant tape if necessary.
- Start Transfer: Close the lid and initiate the heat press process. The machine will apply heat and vacuum pressure.
- Remove Film: Once the transfer is complete and the machine signals, carefully open the lid (using heat-resistant gloves). Peel off the sublimation film while the item is still hot for best results.
