In the world of custom apparel and product decoration, Direct-to-Film (DTF) printing has emerged as a game-changer. This innovative technique allows businesses to create vibrant, durable designs that can be transferred onto a variety of materials. At the heart of the DTF process lies the DTF transfer film, which plays a crucial role in ensuring high-quality prints. This blog will explore the types of DTF transfer films, their uses, and the best practices to get the most out of this versatile printing method.
What is DTF Transfer Film?
DTF (Direct-to-Film) transfer printing is a relatively new and increasingly popular method for transferring designs onto fabric, garments, and other materials. Unlike traditional screen printing or heat transfer vinyl (HTV), DTF printing offers high-quality, full-color prints with remarkable precision and durability.
DTF transfer film is a special type of film that is used in conjunction with a DTF printer and heat press. It serves as the medium that holds the printed design before it is transferred onto the final product. DTF transfer films are typically coated to ensure that the ink adheres to the film and can later be transferred effectively to the fabric.
Key Features of DTF Transfer Film:
- Special Coating: DTF transfer films are coated with a layer that holds the ink. This ensures that the print is sharp, vibrant, and adheres well to the material when heat-pressed.
- Durability: The prints created with DTF transfer films are known for their durability and long-lasting qualities. The ink remains vibrant even after multiple washes.
- Versatility: DTF transfer films work with a wide range of fabrics, including cotton, polyester, and blends, as well as non-fabric items like wood, leather, and glass.
Types of DTF Transfer Film
There are several different types of DTF transfer films available, each designed for specific uses and materials. Choosing the right film is crucial for achieving the best results with your DTF printing process. Below are the most common types of DTF transfer films:
1. PET Film (Polyester Film)
PET (Polyethylene Terephthalate) is one of the most commonly used materials for DTF transfer films. It is a type of polyester film known for its strength, flexibility, and ability to hold vibrant colors.
Characteristics:
- High-quality transfer
- Flexible and tear-resistant
- Works well with various fabric types
- Ideal for high-volume printing and bulk orders
Best Uses: PET films are used for a wide range of applications, including t-shirts, hoodies, bags, and other textiles. They are often chosen for their excellent print quality and ease of use.
2. Matte DTF Transfer Film
Matte DTF transfer films are designed to produce prints with a soft, non-reflective finish. This type of film gives a more subtle, premium look to designs and is often used for higher-end apparel.
Characteristics:
- Soft, non-glossy finish
- Subtle texture that provides a premium feel
- Durable and scratch-resistant
Best Uses: Matte DTF films are ideal for creating stylish, understated designs on clothing items such as high-end t-shirts, fashion apparel, and accessories. This type of transfer film is often used in boutique or premium clothing lines.
3. Glossy DTF Transfer Film
Glossy DTF transfer films are the opposite of matte films, providing prints with a shiny, high-gloss finish. These films enhance the color vibrancy of the design, making them ideal for bold and eye-catching graphics.
Characteristics:
- High-gloss finish
- Vibrant colors that pop
- Smooth surface for fine detail
Best Uses: Glossy DTF films are perfect for bright, bold, and attention-grabbing designs. They are commonly used for custom t-shirts, promotional items, sports apparel, and fashion accessories.
4. Clear DTF Transfer Film
Clear DTF transfer films are transparent, allowing for designs to be transferred directly onto substrates like glass, wood, or clear acrylic surfaces. These films are versatile and can be used for a range of decorative and custom printing applications.
Characteristics:
- Transparent and flexible
- Ideal for a variety of non-fabric applications
- Durable and easy to handle
Best Uses: Clear DTF films are used in custom printing for non-textile items like phone cases, glassware, mugs, signs, and promotional items. They provide an excellent finish for custom designs on hard surfaces.
5. Super White DTF Transfer Film
Super white DTF films feature an extra layer of white coating, which is essential for printing vibrant colors on dark fabrics. The white layer acts as a base, allowing for better color reproduction on fabrics that would otherwise cause the design to appear dull or faded.
Characteristics:
- Extra white coating for better color vibrancy
- Works well on dark-colored fabrics
- Provides a solid base for detailed designs
Best Uses: Super white DTF films are perfect for printing on dark or black fabrics. They are commonly used in custom apparel printing, including t-shirts, hats, and jackets, where bright, vivid designs are needed.

Best Practices for Using DTF Transfer Film
To achieve the best results with DTF transfer films, it’s essential to follow proper best practices during the printing and heat transfer process. Below are some key tips for successful DTF printing.
1. Choosing the Right Transfer Film
Choosing the appropriate type of DTF transfer film based on your project requirements is crucial. For example, if you're working with dark fabrics, consider using a super white film to ensure your design pops. Similarly, if you're aiming for a soft feel on the fabric, a matte film may be more suitable. Always assess the final look you're trying to achieve and select the appropriate film.
2. Correct Printer Settings
Ensure that your DTF printer is calibrated and configured to the correct settings for the type of film you're using. Using the wrong printer settings can lead to poor adhesion or poor print quality.
- Adjust ink density and resolution settings to match the film type.
- Use high-quality inks that are compatible with your transfer film.
3. Proper Film Handling
DTF transfer films are delicate and should be handled with care. Avoid touching the printed surface with your hands, as oils or dirt can affect the final result. Always store films in a cool, dry place to prevent them from becoming damaged.
4. Adhesive Powder Application
After printing your design on the DTF film, it is necessary to apply adhesive powder before heat pressing. The adhesive powder helps bind the ink to the fabric during the heat transfer process. Ensure an even, light coating of powder to avoid clumps or excess that could affect the print quality.
5. Using the Right Heat Press Settings
The success of your DTF transfer depends heavily on the heat press settings. Too high a temperature or pressure could damage the transfer, while too low might result in poor adhesion.
- Set the heat press to the appropriate temperature (usually between 160-180°C or 320-350°F).
- Apply even pressure for the recommended amount of time (typically 10-15 seconds).
6. Post-Transfer Care
After heat pressing, it’s important to let the transfer cool down before peeling off the film. This helps ensure that the design stays intact and adheres properly to the fabric.
