   • Ensure it is coated specifically for sublimation.

2. Sublimation Printer

   • A printer equipped with sublimation ink (popular brands include Sawgrass and Epson).

3. Sublimation Paper

   • Specially coated paper to hold the sublimation ink.

4. Heat Resistant Tape

   • To secure your design to the tumbler.

5. Heat Source

   • A tumbler press or convection oven.

6. Heat Resistant Gloves

   • Protect your hands when handling hot items.

7. Butcher Paper or Parchment Paper

   • To wrap around the tumbler and protect it from ink bleeding.

8. Design Software

   • Use software like Adobe Illustrator, Canva, or CorelDRAW to create your design.

9. Lint-Free Cloth or Alcohol Wipes

   • To clean the tumbler before sublimating.

Step-by-Step Guide to Sublimating a 20 oz Tumbler

Step 1: Create Your Design

Start by designing your artwork. Ensure the dimensions of your design match the tumbler’s printable area. For a 20 oz straight tumbler, this is typically around 9.3 inches wide by 8.2 inches tall, but check your specific tumbler measurements.

1. Open your design software and create a new document with the correct dimensions.

2. Add graphics, text, or patterns. Be as creative as you like!

3. Remember to mirror your design before printing to ensure the text and graphics are correctly oriented on the final product.

Pro Tip: Use high-resolution images (300 DPI) for the best results.

Step 2: Print Your Design

1. Load sublimation paper into your printer.

2. Set your printer to the correct settings:

   • Paper type: Sublimation paper

   • Print quality: High

   • Color mode: CMYK or the mode recommended by your ink manufacturer.

3. Print your design onto the sublimation paper and allow it to dry completely before handling.

Step 3: Prepare the Tumbler

1. Use a lint-free cloth or alcohol wipe to clean the surface of the tumbler. This removes dust and oils that could interfere with the sublimation process.

2. Allow the tumbler to dry completely before proceeding.

Step 4: Attach the Design

1. Wrap your printed design around the tumbler, ensuring it aligns perfectly with the edges.

2. Use heat-resistant tape to secure the design in place, making sure there are no gaps or wrinkles.

3. Wrap the tumbler with butcher paper or parchment paper to protect your heat source from stray ink.

Pro Tip: Tape securely to avoid ghosting or shifting during the heating process.

Step 5: Sublimate the Tumbler

Using a Tumbler Press:

1. Preheat the tumbler press to the recommended temperature (typically 375°F to 400°F).

2. Place the wrapped tumbler in the press and apply even pressure.

3. Heat for 50-70 seconds, depending on your press and tumbler.

4. Rotate the tumbler 180 degrees and heat for an additional 50-70 seconds for even coverage.

Using a Convection Oven:

1. Preheat the oven to 375°F to 400°F.

2. Place the wrapped tumbler inside a shrink wrap sleeve or secure with additional tape.

3. Use a heat gun to shrink the sleeve tightly around the tumbler.

4. Place the tumbler upright in the oven on a heat-resistant surface or tumbler stand.

5. Heat for 5-7 minutes, rotating halfway through for even coverage.

Step 6: Cool and Unwrap

1. Carefully remove the tumbler from the press or oven using heat-resistant gloves.

2. Let it cool slightly, then gently remove the tape, butcher paper, and sublimation paper.

3. Inspect your tumbler to ensure the design has transferred completely and evenly.

Pro Tip: If you notice any imperfections, troubleshoot by adjusting the heat, pressure, or time for your next project.

Tips for Success

• Test First: Use a scrap tumbler or older design to test your settings before sublimating a new batch.

• Pressure Matters: Ensure even pressure to avoid faint or uneven designs.

• Work in a Clean Environment: Dust and lint can affect the transfer process.

• Double-Check Alignment: Misaligned designs can ruin a project, so take your time.

Troubleshooting Common Issues

1. Faded or Light Colors

• Cause: Insufficient heat, pressure, or time.

• Solution: Increase one or more of these variables slightly and retest.

2. Blurry or Smudged Design

• Cause: The design shifted during the process.

• Solution: Use more heat-resistant tape to secure the paper.

3. Ghosting (Double Images)

• Cause: The tumbler moved after heating began.

• Solution: Ensure the tumbler is securely wrapped and handled carefully.

Final Thoughts

Sublimating a 20 oz tumbler is a rewarding and creative process that allows you to produce beautiful, customized items. With practice and attention to detail, you’ll be able to create high-quality tumblers that are perfect for gifts, personal use, or selling in your small business.

Take your time, experiment with different designs, and most importantly, have fun! Happy sublimating!
