The Most Popular 16 x 20 Heat Press Machine in the Industry

I have a 50 year old Sears Craftsman 5hp 12" table saw in my shop that I purchased years ago at an industrial sale. It's an absolute beast of a machine and after 50 years of duty in a high-volume cabinet shop, it ended up in mine for a mere $400. It cuts up to 5" raw wood beams like butter.

I love tools like that. Just like I love my George Knight DK20S heat press that shares a space in my shop opposite that old tank of a table saw. I have a suspicion that in 30-40 years, someone else may end up with my DK20S in their shop. And I bet it will still work like it does now for me.

That's because DK20S heat presses are built the same way as that old saw - to last.

Is the DK20S a sublimation heat press machine?

The DK20S is a sublimation heat press machine. The swing-away design makes it ideal for sublimation by allowing the operator full access to the pressing table with a swing of the handle.

The heat platen uses SuperCoil-Microwinding heater technology, a system of embedded heater windings that wind tightly and closely together throughout the entire platen for extremely even heat, fast recovery & fast heat up times.

What it takes to be a sublimation press:

  • Top "swings-away" for full access to pressing table
  • Even pressure across all 4 corners
  • Consistent heat across all 4 corners
  • Digital controls and timer
  • Solid steel construction designed for heavy use

Check the specs and the DK20S checks all the boxes.

Sublimation transfers require anywhere from 375° to 425° F and demand serious force in pressing often from 40-80 psi. With a DK20S you know you're going to get consistent heat and consistent pressure every single time.
