DTF Film Transfer Process Explained: From Printing to Heat Pressing

Direct-to-Film (DTF) printing has gained significant popularity in recent years as an efficient and effective method for creating vibrant prints on various materials. Unlike traditional printing methods, DTF printing involves printing designs onto a special film, which is then transferred to fabrics and other surfaces using heat press technology. This method provides a smoother and more durable finish, making it the go-to choice for businesses offering custom prints.

If you're new to DTF printing or looking to streamline your process, understanding the DTF film transfer process from printing to heat pressing is key. In this blog, we’ll break down each step in the process and help you understand how to achieve the best results.

Step 1: Preparing the Design

Before you begin printing, the first step is preparing your design. Whether you’re printing a custom logo, artwork, or graphic, your design needs to be ready for transfer onto the DTF film. The design should be created using graphic software such as Adobe Illustrator or CorelDRAW and saved in the appropriate format, resolution, and color profile for the best print quality.

It's also important to consider the material you're printing on (cotton, polyester, etc.) and adjust your design accordingly. You can make the colors more vibrant or tweak the design to fit different fabric types.

Step 2: Printing the Design onto the DTF Film

Once your design is ready, it’s time to print it onto the DTF film. DTF printers are specifically designed to print onto special transfer films.

This process involves printing the design in reverse (mirror image) onto the film. The PET (Polyethylene Terephthalate) film is coated with a special layer that allows for better adherence of the ink. DTF printers typically use CMYK (cyan, magenta, yellow, and black) ink along with white ink to create vibrant and detailed prints.

The white ink helps designs stand out more clearly on dark or colored fabrics. This is a key advantage of DTF printing over other methods like sublimation, where white designs may not show up well on non-white fabrics.

Step 3: Applying Adhesive Powder

After the design is printed onto the DTF film, the next crucial step is applying the adhesive powder. The powder is necessary for ensuring that the ink adheres properly to the fabric during the transfer process.

The printed DTF film is passed through a machine that applies the adhesive powder evenly onto the ink. Any excess powder is then removed. After this, the film is ready to be cured.

DTF adhesive powder is typically a polymer-based product. When heat is applied, the powder melts and helps bond the ink to the fabric. This adhesive powder ensures that the transfer will be durable and resistant to wear.

Step 4: Curing the Film and Adhesive Powder

Once the adhesive powder has been applied, the DTF film needs to be cured. This is done by heating the film using a curing oven or heat tunnel. The heat causes the adhesive powder to melt, bonding the ink to the film and ensuring the print is durable and long-lasting.

Curing also ensures that the transfer is resistant to fading, washing, and general wear. Proper curing is essential for achieving a high-quality and long-lasting print.

Step 5: Preparing the Heat Press

Once the film has been cured, the next step is to prepare the heat press. The heat press is where the transfer takes place, and it is the most critical stage in the DTF transfer process because it transfers the design from the film to the fabric.

Make sure your heat press is set to the correct temperature and pressure for the type of material you’re printing on. The fabric should be clean and wrinkle-free to ensure the transfer is smooth and even.

Typically, DTF transfers require a heat press temperature of around 160°C to 170°C (320°F to 340°F), with a press time ranging from 15 to 30 seconds depending on the material.

Step 6: Applying the Transfer

Place the DTF film onto the fabric, making sure the printed side is facing the material and the adhesive side is facing up. Align the design properly to ensure it’s positioned exactly where you want it.

Once aligned, apply the correct heat and pressure using the heat press. The heat causes the adhesive to bond to the fabric, transferring the design onto the material.

Step 7: Removing the Film

After the transfer is complete, carefully peel the DTF film off the fabric. It’s important to let the film cool down a bit before peeling it off to avoid damaging the design. Once the film is removed, the design should be permanently bonded to the fabric.

If your design has intricate details, it’s important to peel the film slowly and carefully to avoid any smudging or distortion. After peeling, the design should be vibrant and durable, with no fading or cracking.

Step 8: Final Touches

After the transfer is complete, check to ensure the design is fully adhered to the fabric. The print should be vibrant, smooth, and free of any cracks or peeling. If necessary, you can use the heat press again to press the transfer further and ensure a stronger bond.

The print should now be ready for wear, sale, or use in custom products. DTF transfers are highly durable, and with proper care, they can withstand washing and other wear, keeping the design vibrant for a long time.

Types of DTF Film
