Experiencing white ink running on your DTF PET film? Here’s some advice:
Tip 1: Adjust white ink loading
Recommended white ink resolution: 70–80%.
Using 100% can create a solid base but may cause bleeding. Reduce ink if bleeding occurs.
Tip 2: Use double-sided frosted DTF PET film
With 6 coating layers, it absorbs more ink than single-sided film (5 layers), reducing issues.
Tip 3: Use a heating plate
Dry the ink immediately after printing.
Many commercial DTF printers have a built-in heating plate; newer models may have two (before and after printing) for optimal drying, especially in cold environments or with high white ink coverage.

Tip 4: Check for moisture in the PET film
Moisture affects ink absorption.
Dry the film with a hair dryer on low or use the heat platen (before or after printing) to reduce moisture and prevent excess powder sticking.
Tip 5: Adjust multiple white ink heads
If using multiple heads, you can set one higher and one lower or both lower to balance ink coverage and avoid issues.
