Sublimation glass coasters are quickly becoming a must-have item in both homes and businesses.

With the rise of personalised gifts and custom decor, sublimation glass coasters are leading the way. Let’s explore why.
What Are Sublimation Glass Coasters?
Definition and Composition
Sublimation glass coasters are specialised drinkware accessories made from tempered or frosted glass, designed to hold high-quality sublimation prints. Unlike traditional coasters, their surface is coated with a polyester layer that allows vibrant inks to bond permanently during the heat press process.
These coasters typically come in various shapes—square, round, or hexagonal—and often include rubber feet to prevent slipping.
Types of Glass Used in Sublimation Coasters
The most commonly used types include:
- Tempered Glass: Resistant to heat and breakage.
- Frosted Glass: Offers a semi-opaque, elegant finish.
- Clear Glass: Provides a crystal-clear appearance, ideal for high-definition photo prints.

The Sublimation Process Explained
Step-by-Step Printing Guide
-
Design Preparation: Create your artwork using design software (e.g., Photoshop or Canva).
- Print on Sublimation Paper: Use sublimation ink and a compatible printer.
- Align with Coaster Surface: Secure the paper to the coaster with heat-resistant tape.
- Flat Heat Press: Press at 180°C for about 3-5 minutes depending on the coaster’s thickness.
- Cool & Peel: Allow to cool before removing paper. The design is now permanent.
Tips to Achieve Vivid and Durable Prints
- Preheat the coaster for a few seconds to eliminate moisture.
- Use high-resolution designs.

Comparing Glass Coasters with Other Sublimation Blanks

|---|---|---|
| Finish | Glossy | Matte |
| Durability | High | Medium |
| Water Resistance | Excellent | Poor |

Glass vs. Ceramic Coasters
Glass coasters offer a modern aesthetic and are lighter. Ceramic ones are heavier but absorbent. Choose glass for sleek prints and ceramic for rustic charm.
Glass vs. Slate Coasters
Slate provides a natural, rugged look. However, sublimation glass coasters are more customizable and smoother for high-definition prints.
