DTF Printing Procedures

Printing on DTF (Direct-to-Film) film is an innovative process widely used in custom apparel printing. The process starts with selecting an appropriate printer capable of using special DTF inks, which are typically water-based pigment inks. First, the design is prepared using design software, ensuring the image is mirrored since it will be transferred onto the substrate. Once the design is ready, the DTF film is fed into the printer. It’s essential to use a high-quality PET (Polyethylene Terephthalate) film that provides smooth and even surfaces for better ink adherence. The printer then applies the design directly onto the film layer by layer, starting with the colors and finishing with the white ink layer to ensure the design's vibrancy on various backgrounds.

After printing, the film needs to be coated with a special adhesive powder, often referred to as hot melt powder. This powder sticks to the wet ink, creating a bond that allows the design to transfer effectively to the desired surface. To apply the powder, sprinkle it evenly over the printed design while the ink is still tacky, ensuring every part of the printed area is covered. Excess powder is shaken off, and the film is then cured. Curing typically involves placing the film in a curing oven or under a heat press at specific temperatures for a short period. This step ensures the adhesive powder melts and bonds securely to the ink, preparing the film for transfer.

Finally, the prepared DTF film is transferred onto the substrate, such as a t-shirt or fabric, using a heat press. Place the film design side down on the substrate and press it at the recommended temperature and pressure, typically around 300°F to 320°F for 10-20 seconds, depending on the film and substrate. Once pressed, allow the film to cool completely before peeling it off to reveal a high-quality print. This cooling process ensures the design adheres properly and results in a durable, vibrant finish. The DTF process is versatile and can be applied to various materials, making it a preferred choice for custom printing businesses.
