Description
Full wrap-around, handle-to-handle mug printing in a heavy-duty, made-in-USA press. Built for shops adding sublimated mugs, steins and travel tumblers to the product line — with the kind of even heat and reliability the Digital Knight name is known for.
Why Shops Choose the DK3
True Full Wrap-Around Printing
Prints handle-to-handle and top-to-bottom — images up to 5″ high and as close as 1/2″ from the handle, depending on the mug. Full-bleed transfers, edge to edge.
SuperCoil-Microwinding™ Heat
Heater windings packed tightly across the entire platen deliver even heat, fast recovery and quick heat-up — and the DK3 holds your set temperature instead of dropping to a low idle between presses.
Fits Real-World Mugs
A soft heater liner and fully adjustable clamp compensate for less-than-perfectly-straight mugs. Handles 11, 15 and 16 oz mugs, steins and stainless travel mugs (2.7″–3.4″ diameter).
Digital Control That Repeats
Digital temperature, automatic timer, programmable presets, a cycle counter and end-of-cycle alarms keep results consistent operator to operator — with ±2°F readout accuracy.
Built for Non-Stop Use
Thick solid-steel welded framework and a die-cast clamp assembly stand up to production. The clamp adjusts to very heavy pressure for full-bleed transfers on the most demanding mugs.
Industry-Leading Warranty
Where many mug presses rely on short-lived silicone blankets, the DK3 uses a patented stainless-steel mug-band heater backed by a 3-Year / 3,000-mug warranty and FREE lifetime tech support.
What You Get
The Technology Inside
Stainless-Steel Mug Band
GeoKnight’s patented stainless-steel band heater has proven far more reliable in the field than silicone-blanket designs — and it’s why the platen carries a 3-Year / 3,000-mug warranty.
Always At Temperature
The DK3 heats up in a few minutes and runs constantly at your set point instead of idling low, so every mug in a run sees the same heat from the first press to the last.
Heavy-Pressure Clamp
The die-cast clamp adjusts to very heavy pressure and opens extra-wide for fast load/unload, keeping cycle times short on production runs.
What You Can Make
Personalized Drinkware
Sublimated 11–16 oz coffee mugs, steins and stainless travel mugs — one of the highest-margin add-ons any apparel shop can offer.
Gifts & Promo Orders
Weddings, fundraisers, corporate gifts and team orders — full-wrap photo mugs round out gift lines and pad promotional jobs.
Works With Your Workflow
Compatible with dye-sublimation transfers, heat-transfer materials and Cricut Infusible Ink — pair it with a Sawgrass printer and sublimation paper for a complete setup.
