The Geo Knight DK3 Digital Mug Press – Mug Heat Press Review

The Geo Knight DK3 Digital Mug Press is considered by many to be the best mug heat press.


This machine is built exclusively for pressing mugs, it is not part of a multifunction machine. It presses images from transfer paper onto mugs, and can complete a full wrap (from top rim to the bottom, and from handle to handle).


Let’s take a look at this high quality mug press from Geo Knight. 


Geo Knight Mug Press



The George Knight DK3 Mug Press is one of the most expensive mug heat press machines on the market, and it’s also the best (in my opinion). This is a commercial use mug press that is great for small and large business.
