DTF printing is becoming popular for custom T-shirts and fabric printing. It works on many types of materials and gives bright, long-lasting results. But like any machine, DTF printers can have issues.
In this guide, we’ll go over the most common DTF printing problems and show you how to fix them quickly, even if you’re not a tech expert.
🎯 1. Printhead Gets Clogged
❌ What Happens:
Your printer leaves gaps, faded spots, or lines in the design.
🛠 Why It Happens:
- You don’t use the printer often
- You’re using the cheap or the wrong ink
- The printhead isn’t cleaned regularly
✅ How to Fix It:
- Print something small every day or do a test print to keep the ink flowing
- Use good-quality ink like Winnerjet’s DTF ink, which is made to reduce clogs
- Clean the printhead regularly with the cleaning tools your printer came with
🎨 2. Colors Look Faded or Dull
❌ What Happens:
Your print doesn’t pop—it looks boring or pale.
🛠 Why It Happens:
- You’re using low-quality ink or film
- The software settings are wrong
- The film isn’t cured (dried) the right way
✅ How to Fix It:
- Use high-quality ink and PET film
- Make sure your design software has the correct color settings
- Heat the film at the right temperature (usually 120°C for about 2 minutes) so it dries well
❌ 3. Adhesive Powder Isn’t Sticking
❌ What Happens:
The powder you sprinkle doesn’t stick to the printed area, or it falls off.
🛠 Why It Happens:
- Not enough white ink was printed
- Too much or too little powder was used
- The heat or the room humidity isn’t right
✅ How to Fix It:
- Make sure your printer prints enough white ink underneath the design
- Shake off the extra powder gently and cure it evenly
- Work in a room with normal humidity (about 50%)
👕 4. Film Doesn’t Peel Off Cleanly
❌ What Happens:
The film tears or ruins your design when you try to peel it off.
🛠 Why It Happens:
- You’re using the wrong film type (hot peel vs. cold peel)
- You didn’t wait long enough (for cold peel)
✅ How to Fix It:
- Check the label: Is it hot peel or cold peel film? Follow the instructions
- If using cold peel, let the print cool down completely before peeling
- Winnerjet’s cold-peel film peels off cleanly and doesn’t leave a mess
🧺 5. Print Cracks or Peels After Washing
❌ What Happens:
The design looks great at first, but starts cracking or peeling after a few washes.
🛠 Why It Happens:
- Cheap materials (film, ink, powder)
- Wrong temperature or time when heat pressing
- The fabric isn’t suitable for DTF
✅ How to Fix It:
- Use trusted DTF products that are made to last
- Heat press your print at 160–170°C for 15–20 seconds
- Choose fabrics like cotton, polyester, or blends
🔁 BONUS: Tips to Avoid DTF Headaches
- 🧽 Clean regularly: Wipe the printhead, capping station, and other parts once a week
- 🖨 Test print daily: Even a small print can prevent ink clogs
- 🌡 Control room temperature and humidity: Too much moisture can cause printing and curing problems
- ✅ Use matching supplies: Not all films, inks, and powders work well together

❓ FAQ: Common DTF Printing Questions
Q1: Why does my DTF print look blurry?
Blurriness can happen if there’s too much ink or the film moves during printing. Try adjusting the print settings and make sure everything is flat.
Q2: Can I use any PET film?
No. Only use DTF-specific PET film that’s made to handle heat and powder properly.
Q3: How do I check if my curing temperature is right?
Use an infrared thermometer to make sure the film surface reaches around 120°C (248°F).
Q4: What fabrics work best with DTF printing?
DTF works great on cotton, polyester, denim, and fabric blends.
Q5: Can I leave ink in the printer if I don’t use it for a few days?
No. If you won’t use the printer for more than 2 days, run a test print or clean the printhead to avoid clogs.
