Direct to Film (DTF) printing is a modern textile decoration method that has transformed the custom apparel industry. It involves printing designs onto coated PET film and then heat-transferring them onto garments using a specialised adhesive and heat press.
With compatibility across a wide range of fabrics and no need for pre-treatment, DTF stands out for its speed, versatility, and vibrant results.
How DTF Printing Works: Step-by-Step
Here is how Direct to Film (DTF) Printing works:
1. Artwork Preparation
- Designs are created or imported using graphic software such as Adobe Illustrator, Photoshop, or CorelDRAW.
- Colour profiles (ICC) are applied for accurate reproduction based on the printer and ink combination.
2. Printing the Design
- A dedicated DTF printer prints the design in reverse onto PET film.
- White ink is printed first (for opacity), followed by CMYK colours.
3. Adhesive Powder Application
- While the ink is still wet, thermoplastic polyurethane (TPU) powder is applied manually or using an automatic powder shaker.
- Excess powder is removed to avoid clumps or residue.
4. Curing the Film
- The powdered film is heated in a curing oven or using a shaker with an integrated heater (120°C–140°C for ~2–3 minutes).
- This melts the powder just enough to bind with the ink.
5. Transferring the Design
- The film is positioned on the garment, ink side facing the fabric.
- A heat press applies heat (typically 160°C) and pressure for 15–20 seconds.
- The film is then peeled off after cooling (cold or warm peel, depending on film type).
6. Optional Final Press
- A second press with parchment paper helps flatten the print, improve wash resistance, and soften the hand feel.

- Fast Turnaround: Simplifies workflow with quick processing times.
- Durability: Transfers are long-lasting and resistant to multiple washes.
- Eco-Conscious Options Emerging: Many manufacturers are developing biodegradable powders and recyclable films.
Limitations of DTF Printing
- Equipment Costs: Requires investment in printers, heat press, films, and curing devices.
- Learning Curve: Operators must master powder application, curing, and peeling timing.
- Thicker Print Layer: The final print can feel more rubbery than screen or sublimation prints.
- Flat Surfaces Recommended: Best suited for garments or items with smooth, pressable areas.
- Environmental Factors: TPU powder and PET film must be responsibly managed to reduce waste.
