A sublimation mug is a ceramic, enamel, glass or polymer mug coated with a special polymer layer that bonds with sublimation ink when heat and pressure are applied. This process permanently embeds the print into the surface, creating vibrant, dishwasher-safe designs that won’t peel or fade.

A mug must have a polyester-based polymer coating that reacts to sublimation ink during heat transfer. Standard mugs without this coating will not accept sublimation prints. The mug should also be able to withstand high temperatures in a mug press or oven without cracking or warping.

Sublimation works on coated ceramic mugs, enamel mugs, polymer mugs, glass mugs and many stainless-steel travel mugs. The key requirement is a high-grade polymer coating compatible with sublimation inks. Each material offers a different look, durability and print finish.

The 11oz white ceramic mug is widely recommended for beginners due to its predictable heat response, consistent coating quality and compatibility with most mug presses. It offers the easiest way to achieve reliable, vibrant results.

No. Only mugs with a polyester-based sublimation coating will accept sublimation prints. Standard white mugs from supermarkets or wholesalers without this coating will not produce a proper transfer.

Print your design on sublimation paper using sublimation ink, tape it tightly to the mug, and press at 180–200°C for 180–240 seconds depending on your press. Remove the paper immediately and allow the mug to cool. Consistent pressure and correct timing help avoid ghosting, banding and faded areas.

Faded prints are usually caused by insufficient heat, short press times, or poor pressure. Ensure your mug press reaches the correct temperature, use quality sublimation paper and ink, and confirm the mug has a proper polymer coating. Moisture in the paper or mug can also reduce vibrancy.

Ghosting happens when the paper shifts during pressing. Prevent this by taping the transfer securely, using high-quality heat-resistant tape, and applying even pressure in the press. Remove the paper immediately after pressing to avoid secondary heat marks or shadowing.

Yes — high-quality sublimation mugs are tested for durability, often surviving thousands of dishwasher cycles without fading. The print is fused into the coating, not applied on top, making it far more durable than vinyl or transfer prints. Our ULTRA A+ Sublimation Mugs are independently tested for 3,500 dishwasher cycles and our other mugs are also tested for a high number of cycles too.

Ceramic mugs give classic glossy prints and are best for everyday use. Enamel mugs have a vintage look and are lightweight. Polymer mugs are shatterproof and ideal for children or outdoor settings. Glass mugs offer a modern, premium feel with frosted or clear finishes.

Most ceramic and enamel mugs work in standard mug presses. Glass, polymer and travel mugs may require adjustable wraps or a convection oven for even heat distribution. Always check the product’s recommended pressing method before printing. Sublimation latte mugs require a different element due to their conical shape that will not work in a standard 11oz element.
