Instructions:
 
• Set the temperature of your press to 356F and put 180 seconds on the timer. 
• Mirror the image before you print it on sublimation paper. 
• Use high heatproof tape to secure the paper tightly around the mug. 
• Do not preheat the mug. As soon as the sublimation paper touches heat the image will activate. Make sure it is centered in the cuff and the handle of the mug is to the far left. 
• Press down the lever. If you use a World Paper mug press the timer will start automatically each time. 
• Just wait for the beep and release the mug from the machine. Be careful, it's hot. Make sure to only hold it by the handle.
