How to Do Sublimation on DTF Film?

For users of sublimation printing, one of the biggest challenges has always been the limitation of printing only on polyester fabrics. Now, with the release of a brand-new product from Koala Paper — sublimation on DTF film — that barrier is finally broken.

This innovative solution allows you to use your existing sublimation printer and ink to transfer vibrant designs onto cotton, canvas, and other non-polyester materials, without the need for costly upgrades. In this guide, we’ll walk you through the full process of using this technology, so you can quickly get started with confidence.

What You'll Need

Before you begin working with sublimation on DTF film, make sure you have the following supplies on hand:

• A sublimation printer (e.g. Epson L805, L1800)
• Sublimation ink (no need to switch)
• Koala Paper’s sublimation DTF film
• DTF hot-melt powder (we recommend a fine, eco-friendly formula)
• A heat press or manual heat transfer machine
• Cotton, canvas, poly-cotton blends, or other non-polyester materials

? One of the biggest advantages of this method is that it’s fully compatible with dtf with sublimation ink. There’s no need to modify your printer or switch to pigment-based inks — high-quality transfers are totally achievable as-is.

Step-by-Step Printing Process

Step 1: Print Your Design onto the DTF Film

Use a sublimation printer to print your design in mirror image onto the matte side of Koala Paper’s sublimation DTF film.
For best results, choose a high-resolution print mode such as “Photo” or “Fine” to capture detailed lines and vivid color.

Step 2: Apply Powder and Cure

While the ink is still wet, evenly sprinkle DTF hot-melt powder over the printed design.
Shake the film gently to ensure the powder coats the image fully, and pour off any excess.
Then, use a heat plate or heat gun to cure the powder at around 110°C (230°F) for about 2 minutes, allowing it to slightly melt and bond to the ink.

Step 3: Transfer the Design with a Heat Press

Place the printed film face-down on the surface of your fabric (we recommend pre-pressing the fabric to flatten it).
Set your heat press to 160°C (320°F) and press for 20 seconds with medium pressure.
After pressing, remove the film and let it cool down to room temperature.

Step 4: Cold Peel to Complete the Transfer

Once the design has fully cooled, gently peel away the film.
Your image should remain cleanly on the fabric, with a smooth feel, no excess powder, and no color bleed — perfect for daily wear and washing.

Pro Tips and Best Practices

• Print Settings: Avoid “draft” or “high-speed” modes. Opt for high-resolution output for sharper prints.
• Powder Application: A mesh sifter helps distribute the powder evenly, avoiding clumps or uneven edges.
• Heat Press Pressure: Medium pressure gives the best results. Too much may leave marks; too little can affect adhesion.
• Washing Instructions: Let the garment rest for 24 hours before washing to maximize the image’s lifespan.
