We’ll also dive into step-by-step instructions, troubleshooting tips, and creative ideas to help you get the most out of sublimating on glass surfaces.
In this Sublimation on Glass Guide, we’ll take a look at:
What is Sublimation on Glass?
Sublimation is a heat transfer process where sublimation ink is converted into gas under high temperatures, bonding with the surface of the substrate. In the case of sublimation on glass, the process allows the ink to fuse with the special coating on the glass, resulting in vivid and permanent designs that won’t peel or fade over time.
Unlike traditional screen printing or vinyl transfers, sublimation penetrates the surface of the glass, creating a more durable and scratch-resistant design. This technique is perfect for personalized items such as photo frames, glass plaques, coasters, ornaments, and glass signage.
Why Choose Sublimation on Glass?
Sublimation on glass is an attractive option for several reasons:
- Vibrant Colors: Glass provides a clear and glossy surface, allowing sublimated designs to stand out with bold, vibrant colors.
- Durability: Sublimated glass items resist scratching and fading, making them ideal for long-lasting custom products.
- High-End Look: Glass adds a touch of elegance to custom designs, making it a popular choice for premium gifts, home décor, and awards.
- Customization: Sublimation allows for highly detailed designs, including photos, text, and intricate patterns, offering endless possibilities for personalization.
Materials Needed for Sublimation on Glass
You will need the right equipment and materials to achieve successful results with sublimation on glass. Here’s a list of the essentials:
- Sublimation Printer: A sublimation printer must print your designs using sublimation ink. Common brands include Epson and Sawgrass.
- Sublimation Ink: Special sublimation ink that turns into gas under heat is required to create the design.
- Sublimation Paper: Heat-resistant sublimation transfer paper holds the ink before transferring it to the glass surface.
- Heat Press: A heat press machine that can reach temperatures around 400°F is needed to transfer the design onto the glass.
- Glass Blanks: These are pre-coated glass products designed specifically for sublimation. Common glass blanks include coasters, photo frames, and plaques.
- Heat-Resistant Tape: This tape secures the sublimation paper to the glass and prevents shifting during the heat press process.
- Protective Sheets: Teflon or butcher paper protects your heat press and glass from excess ink during transfer.
- Silicone Pad: A silicone pad may be necessary to distribute heat evenly on the glass and provide a soft surface for pressing.
Step-by-Step Guide to Sublimation on Glass
Now that we’ve covered the basics, let’s walk through the step-by-step process of sublimation on glass.
Step 1: Prepare Your Design
The first step is to create or select a design that will be transferred onto the glass. You can use graphic design software like Adobe Illustrator, Photoshop, or CorelDRAW to create your artwork. Ensure your design is high resolution (at least 300 DPI) to ensure a crisp and clear final product.
Step 2: Print the Design
Once your design is ready, print it onto sublimation paper using sublimation ink. Remember to mirror your design, which will be reversed when transferred onto the glass.
Step 3: Clean the Glass Surface
Before sublimating, clean the glass surface thoroughly to remove any dust, fingerprints, or oils. This ensures that the design adheres properly without imperfections.
Step 4: Position the Design on the Glass
Place the printed sublimation paper face down onto the glass surface. Use heat-resistant tape to secure the paper in place, ensuring no wrinkles or bubbles could affect the final print.
Step 5: Prepare the Heat Press
Preheat your heat press to around 400°F (204°C), the typical temperature for sublimation on glass. Adjust the pressure settings to medium, as too much pressure can crack the glass.
Step 6: Press the Glass
Place the glass blank in the heat press with the sublimation paper facing up. Add a protective Teflon sheet or butcher paper to prevent ink from transferring onto the heat press. Press the glass for 3-5 minutes, depending on the thickness of the glass and the manufacturer’s recommendations.
Step 7: Cool the Glass and Remove the Paper
After pressing, carefully remove the glass from the heat press. Let it cool completely before peeling off the sublimation paper to reveal your vibrant design.
Step 8: Inspect the Final Product
Once cooled, inspect the glass for any imperfections. Your project is complete if the design is transferred cleanly and looks vibrant!
Creative Ideas for Sublimation on Glass
Sublimation on glass opens up a world of creative possibilities. Here are a few ideas to inspire your next project:
1. Personalized Photo Frames
Create custom photo frames with sublimated designs featuring names, dates, or special messages. These make great gifts for weddings, birthdays, or anniversaries.
2. Glass Coasters
Sublimated glass coasters are both practical and decorative. You can create sets of coasters with custom designs, family photos, or company logos.
3. Custom Glass Plaques
Glass plaques with sublimated text and images make elegant awards or recognition pieces for businesses or special events.

Troubleshooting Common Issues with Sublimation on Glass
While sublimation on glass can yield beautiful results, you may encounter some common challenges. Here’s how to troubleshoot these issues:
1. Faded Colors or Dull Prints
- Cause: The temperature or time may not be set correctly on the heat press.
- Solution: Increase the pressing time or temperature and ensure the glass is pre-coated for sublimation.
2. Uneven Prints or Blurry Designs
- Cause: The sublimation paper may have shifted during the pressing process.
- Solution: Use heat-resistant tape to secure the paper tightly to the glass and ensure there’s even pressure across the surface.
3. Cracking or Breakage
- Cause: Too much pressure or rapid temperature changes.
- Solution: Use medium pressure and allow the glass to cool gradually after pressing. Avoid exposing the glass to extreme temperature changes.
4. Ink Spots or Residue
- Cause: Ink may have transferred to the heat press or uneven areas on the glass.
- Solution: Use protective sheets, such as Teflon or butcher paper, to prevent ink from bleeding onto the press. Ensure the glass surface is clean before pressing.
Benefits of Sublimation on Glass
Sublimation on glass offers several advantages over other printing methods, making it a great choice for personalized items:
- Durability: Sublimated designs on glass are long-lasting, resistant to scratches, and won’t fade over time.
- High-Quality Finish: The sublimation process creates vibrant, full-color designs that appear sharp and crisp on glass surfaces.
- Customization: With sublimation, you can create highly detailed, personalized designs, including photos, text, and graphics.
- Versatility: Glass can be used for a wide range of products, from coasters and plaques to photo frames and ornaments, making it a versatile material for creative projects.

Sublimation on Glass FAQ
What type of glass can be used for sublimation?
Only specially coated glass, also known as sublimation glass blanks, can be used for sublimation on glass. These glass items have a polymer coating that allows the sublimation ink to bond with the surface during the heat transfer. Regular, uncoated glass will not work for sublimation, as the ink will not adhere properly.
What temperature and time settings should I use for sublimating on glass?
For most sublimation on glass projects, you should set your heat press to around 400°F (204°C) and apply medium pressure for 3 to 5 minutes. The exact time may vary depending on the thickness of the glass and the manufacturer’s recommendations, so always refer to the guidelines provided for your specific blanks.
How do I prevent the glass from cracking during sublimation?
To prevent cracking, use medium pressure during the sublimation process and allow the glass to cool down gradually after pressing. Avoid rapid temperature changes, such as placing hot glass in cold environments, as this can cause the glass to crack due to thermal shock.
