A sublimation tumblers FAQ list is here for you.
We’ll walk through the top 10 FAQs about sublimation tumblers, and hope they will be helpful to you.
About the sublimation tumblers (for new and beginners)
Before start, we’d like to address two common sublimation tumbler questions beginners often ask: what a sublimation tumbler is and how to do. (If you already know this, feel free to skip ahead.)
What is a sublimation tumbler?
A sublimation tumbler is basically a cup with a special coating that lets you transfer any design, such as names, photos, or fun graphics, onto it. Unlike stickers or paint, these designs on sublimated tumblers are smooth, vibrant, and long-lasting.
How to Sublimate a Tumbler？
If you’re new to tumbler sublimation, there is a simple breakdown process to get you started.
1. Gather Your Supplies
You’ll need:
- A sublimation printer and special ink.
- Sublimation paper.
- Sublimation tumbler blanks.
- Heat-resistant tape.
- A tumbler heat press or oven.
2. Prepare Your Design
- Size your artwork to fit the tumbler.
- Mirror your design (important！flip it horizontally) so it prints correctly.
- Print it and let the ink dry.
3. Wrap and Tape
- Wrap the printed paper tightly around the sublimation tumbler blanks.
- Make sure it’s flat with no wrinkles
- Secure with heat-resistant tape
4. Heat It Up
Heat the wrapped tumbler in heat press or oven. Common reference settings(may vary due to the material, thickness, or coating…):
- Tumbler heat press: 360–380°F (182–193°C) for about 50–70 seconds per section, rotating as needed.
- Convection oven: 375–400°F (190–205°C) for about 5–7 minutes.
5. Cool and Reveal
- Let the tumbler cool completely
- Remove the paper
Once everything is complete, you’ll have your own custom-made sublimation tumblers.
Your design is now part of the cup!
10 Top FAQs in Sublimated Tumblers
Now, let’s move on the 10 most frequently asked questions when we sublimated tumblers:
Q1: Why didn’t my design transfer to the tumbler at all?
Sublimation requires special sublimation ink and sublimation paper. Regular ink and paper won’t work. The tumbler also needs a proper sublimation coating.
Solution:
Use true sublimation ink and paper, and make sure the tumbler has a sublimation coating.
Q2: Why are the colors on my sublimation tumblers dull or faded?
Sublimation ink needs enough heat and the right surface to fully “sink into” the tumbler. When either is missing, colors look weak.
Solution:
Try increasing the heat time or temperature. If the issue still happens, the coating on the tumbler may be the problem, so try using sublimation tumbler blanks and run the transfer again.
Q3: Ghosting or double images on sublimation tumblers?
Ghosting happens when the paper moves during or right after heating. The ink is still hot; transform your design again.
Solution:
Secure the design firmly with heat-resistant tape and let the tumbler cool before removing the paper.
Q4: The pattern on sublimation tumbler look blurry or not sharp?
Blurry edges usually come from wrinkles, gaps, or low-resolution artwork. The design isn’t sitting flat against the tumbler surface.
Solution:
Wrap the paper tightly and make sure the design fits the tumbler’s shape. A hot air blower or heat shrink film can be used to help fix the pattern.
Q5: Why do white spots or patches appear after sublimation?
Something blocked the ink during heating. Moisture, dust, or oil on the tumbler or paper can cause white spots.
Solution:
Make sure everything is clean and dry before heating.
Q6: Why does black turn brown on my sublimation tumbler?
Excessive heat burns the black dye, shifting it to brown. When the temp is low, the ink does not fully bond, resulting in a brown color, too.
Solution:
Adjust time and temperature gradually and avoid overcooking the tumbler.
Q7: Can you sublimate on stainless steel tumblers(without coating)?
No. Sublimation ink can’t bond to bare metal. Only stainless steel tumblers with a sublimation coating (we call them sublimation stainless steel tumblers) will work; regular stainless steel tumblers cannot be sublimated.
Solution:
Use stainless steel cups with a sublimation coating instead of ordinary ones.
Q8: Why does my sublimation tumbler smell strange after heating?
This is because the coating is reacting to heat. A slight smell during heating is normal, especially with new sublimation tumbler blanks.
Solution:
Always work in a well-ventilated area and use safe coated sublimation tumblers.
Q9: Can I sublimate a tumbler more than once?
Not recommended. The coating can only absorb so much ink. You can reheat a tumbler briefly to fix light areas, but repeated sublimation can damage the coating and reduce color quality.
Solution:
Use a new sublimation tumbler or adjust the temp and time to achieve satisfactory results in a single heating process.
Q10: Are Sublimation Tumblers Dishwasher Safe?
Sublimation ink becomes part of the coating, not a surface layer, so theoretically, it’s possible. But you know, there is always a difference between theory and practice, so to prevent the pattern from fading or being damaged, hand washing is still recommended.
Solution:
If you cherish your sublimation tumbler, we recommend gentle and safe hand washing. However, if you are very busy or have many alternatives, a dishwasher is also ok.
