DTF (Direct-to-Film) printing begins with file preparation in the DTF RIP software.

Using the right DTF RIP software and DTF printer makes DTF printing easier and ensures you get perfect DTF transfers. In the next sections, we’ll go over each step of DTF printing so you can better understand how it works.

DTF (Direct-to-Film) printing begins with preparing design files ready.

  • Create your design using any graphic software like Photoshop or Illustrator by Adobe.
  • You DTF design needs to be high resolution and in formats such as: PNG, JPG, EPS, or PSD. 
  • You upload your design into your RIP software.
  • Once your files are loaded, you add a layer of white ink over the entire design.
  • For dark fabrics, make sure your design includes a layer in the background layer. It’s the ultimate secret to improve your DTF prints. Your

Can I print DTF without white ink? White ink is essential for DTF printing. Let’s say you want some parts of your design to look brighter (the ones requiring white ink), without the white ink, these parts will look so boring and faded. So please, try not to forget your white ink in DTF printing.

After applying the white layer, you print the design onto a special PET film, designed to work with DTF.

Once the design is printed on the PET DTF film, you can use the adhesive powder and heat to create a lasting transfer onto the garment.

Applying Adhesive Powder

Next, adhesive powder is sprinkled evenly onto the printed design while the ink is still fresh and not completely dry. This creates a strong adhesive layer. It’s important to spread the powder evenly across the design to avoid clumps, as this ensures a smooth transfer.

After the adhesive is added, heat is used to activate it. The printed PET film is either placed in a drying oven or pressed with a heat press. The heat melts the adhesive, which then binds the ink to your PET DTF film.

This will make your DTF print solid and ready for transfer.

Film Removal and Final Pressing 

After transferring your design onto the textile, you can remove the PET DTF film. First, let the transfer cool down a bit. Then, begin peeling the film from the corner with the most ink, making sure to do it very carefully. It’s important to peel off the film carefully while it’s cold to avoid leaving any extra adhesive or residue on the fabric. Doing this step gently will give you a clean DTF design.

The garment is ready for the Final Pressing. The final press helps make sure the ink sticks permanently to the fabric, making the design more durable. It also improves how well the design resists to washing, wear, and other factors.

This means you will be giving your customers long-lasting DTF prints. Now, you can start with packaging and shipping your DTF print.

In the case of multiple designs and DTF workflow automation, you will need a prepress automation software like Caldera PrimeCenter and a cutter like Secabo DTF MultiCut Pro.
