DTF (Direct to Film) transfers have revolutionized the customized attire business, offering a flexible and cost-effective technique for printing vibrant designs on a wide range of fabrics. Whether or not you are a small business owner, hobbyist, or looking to develop your print shop’s services, understanding how DTF transfers work can give you a competitive edge. Here’s a breakdown of all the process from start to finish.
What Is a DTF Transfer?
DTF stands for “Direct to Film,” a printing technique that involves printing a design directly onto a special film, then transferring that design onto fabric using heat and pressure. Unlike traditional methods like screen printing or DTG (Direct to Garment), DTF transfers permit for high-resolution, full-color prints on various materials together with cotton, polyester, blends, and more. They’re especially valued for their flexibility, durability, and ease of use.
Step-by-Step Breakdown of the DTF Process
1. Getting ready the Artwork
The process begins with preparing your digital artwork. The design is created or imported into graphic design software, normally in PNG format with a transparent background. High-resolution files (300 DPI or higher) ensure crisp results. Once the artwork is finalized, it’s mirrored (flipped horizontally) before printing, for the reason that image will be transferred face-down onto the garment.
2. Printing Onto the Film
Using a DTF printer, the mirrored design is printed directly onto a particular PET (polyethylene terephthalate) film. The printer typically makes use of CMYK ink for the colour layer and white ink as a base layer. First, the printer lays down the colour layer, adopted by a white ink layer that makes the design stand out on any fabric color. This twin-layering ensures vibrant colours and strong adhesion.
3. Making use of Hot Melt Adhesive Powder
After printing, a hot melt adhesive powder is evenly utilized to the printed side of the film while the ink is still wet. This powder sticks to the inked areas of the design. The film is then gently shaken or tapped to remove excess powder, ensuring a clean application. The adhesive powder is crucial, as it acts because the bonding agent between the ink and the fabric.
4. Curing the Adhesive Powder
Next, the film with the applied powder is cured utilizing a heat press, oven, or curing station. The goal is to melt the adhesive powder just sufficient to activate it without fully bonding it to the film. Typical curing temperatures range from 300°F to 350°F (149°C to 177°C), and curing time is usually around 2 to three minutes. Once cured, the film is ready for transfer and may be stored for later use.
5. Transferring the Design to Fabric
To use the DTF switch, the film is placed face-down onto the garment. A heat press is used to apply high temperature and pressure—generally round 320°F (160°C) for 15–20 seconds. This prompts the adhesive and bonds the ink to the fibers of the fabric. After urgent, the film is peeled off, revealing the switchred design.
6. Optional Finishing Press
For an additional smooth and durable end, a second press is commonly performed. This involves inserting a parchment paper or Teflon sheet over the design and urgent it once more for 5 to 10 seconds. This step helps embed the ink into the fabric more thoroughly and removes any residual shine from the film.
Advantages of DTF Transfers
DTF technology offers several benefits:
Works on a wide range of fabric types and colors
No weeding or cutting required, unlike vinyl
Wash-resistant and durable prints
Easy to scale for giant orders or one-off designs
Transfers may be pre-made and stored for future use
