Coral 4 Mug Press Instructions

Coral 4 Mug Press


The Coral 4 Mug Press provides you all all-in-one capability to transfer photos, images and words onto mugs. Our popular mug press makes it easy for you to create your own promotional products, gifts, decorations and giveaways. 

Capable of printing on various sized mugs, the Coral 4 Mug Press can handle most of your printing needs.





  1. Before you begin heating, you must adjust the pressure of the device by using the pressure adjust nut. Be sure that the pressure is adequate yet not too tight.
  2. Print your image with a sublimation printer and paper (the maximum image size is 200x90). Cut the paper and attach it to the mug using heat tape. Leave about a 2 cm. gap on each side of the handle.
  3. Place the mug onto the heating mat.
  4. Turn the power on.
  5. Set the time and temperature (recommended pressing time is 180 seconds; recommended temperature is 160 - 200° Celsius. 
  6. Once the allotted 180 seconds have passed, an alarm will sound. Turn off the temperature and time switch and wait 180 seconds before lifting the handle. Remove the mug and peel off the paper. If you find it difficult to remove the paper, we suggest placing the mug into lukewarm water for 30 seconds.
  7. Please remember to turn off the unit after each pressing and never heat the blanket without a mug.  A good option is to use a spare mug to preheat the blanket, or to use between pressing, in order to avoid causing the blanket to burn out.



Potential problems with the Coral 4 Mug Press, and their solutions

Potential problems with your transfer results, and their solutions
