Proper use of DTF Powder is a prerequisite to ensure long-lasting prints. Some companies may encounter some problems when using DTF powder. No need to worry. Follow our easy-to-follow guide to using it for perfect prints!
What is DTF powder？
DTF powder is a special binder. In DTF Printing, heating connects the ink to the fabric, which helps transfer the printed design to various fabrics and provides resistance to washing and abrasion.

Step-by-step guide to using DTF powder
Preparation Steps
- Quality materials: Purchase quality DTF transfer film and suitable DTF powder. The transfer film should have a matte frosted surface for optimal ink adhesion and should be able to withstand high temperatures without curling.
- Print design: Load the DTF transfer film into the printer with the print side facing up.
Covering with DTF powder
- Coverage time: Apply the DTF powder while the ink is still wet.
- Even Distribution: Use a screen or auto disintegrator to distribute the DTF powder evenly over the printed design.
- Dithering: After applying the powder, gently shake off the excess powder so it remains only on the print pattern area.
Curing DTF powder
- Oven Curing: Place the transfer film in a conveyor belt oven to properly cure the ink and powder after covering the powder. Make sure it achieves a glass-like finish.
Transfer Printing
- Heat Press Setup: Place the printed DTF transfer film on the fabric to ensure proper alignment.
- Pressing: Adjust the heat press temperature to approximately 360°F, medium pressure, and press for 30 seconds. After pressing, let the film cool slightly and gently peel it from one corner.
- Back Pressing (optional): For added durability and a polished look, place a layer of t-shirt material or parchment paper on top of the pattern and press again for approximately 15 seconds.

Tips for using DTF powder
- Timing of application: Apply DTF powder to the transfer film before the ink dries to ensure adhesion.
- Even application: Shake the powder with a tool to distribute it evenly over the design area to avoid lumping.
- Shake the powder: Shake off the excess powder carefully after application to maintain the clarity of the pattern.
- Heat settings: Adjust the heat press temperature and pressure settings according to the type of fabric being transferred.
- Powder selection: white powder is suitable for light-colored fabrics, and black powder is ideal for dark-colored fabrics.
Benefits Of DTF Powder
- High print quality: prints with vibrant colors, rich details, and high image reproduction.
- Versatility: Can be used on a wide range of materials such as textile fabrics, metals, glass, ceramics, etc.
- Durability: Prints are very durable and wash resistant, tested over 60 washes without noticeable color fading.
- High adhesion: Ensures the pattern is firmly bonded to the fabric, preventing it from peeling or flaking off over time.
How to Store DTF Powders?
- Temperature range: It is recommended that DTF powders be stored in a temperature-controlled environment, with an optimum temperature of 20°C to 25°C (68°F to 77°F).
- Humidity range: It is recommended that humidity levels be maintained between 30% and 50%. A hygrometer will be used to monitor the humidity level in the storage area.
- Seal containers: Store DTF powders in tightly sealed packages to keep out dust and moisture.
- Expiry date: Check the expiration date of DTF powders regularly, and if the expiration date is imminent, test a sample before use.
- Update stocks: Use obsolete powders first within the optimal shelf life (6 to 12 months).
People’s Frequently Asked Questions
Is DTF powder toxic?
No. However, following the manufacturer’s guidelines for safe use is essential, such as using the powder in a well-ventilated area, wearing a dust mask, and avoiding direct inhalation.
Can you use DTF powder on the sublimation paper?
No, DTF powder is not suitable for sublimation paper. It is an essential part of DTF printing. Using it on sublimation paper will not produce the desired results.
What is the difference between black and white DTF powder?
The colors of the powders themselves are different. Black powder is used less frequently, mainly on dark-colored fabrics, to ensure no residue is left. White powders are used more often, mainly for light-coloured fabrics.
How long do you cure DTF powder?
It usually takes about 2 to 3 minutes to maintain a temperature of 160°C (325°F) in the curing oven.
When to use black DTF powder?
Lumping, hardening, discoloration, adhesion loss, and shelf life expiry
