What is Direct-to-Film (DTF) transfer?

Direct-to-Film (DTF) transfer is a cutting-edge printing technique used primarily in garment decoration. It employs advanced inkjet technology to print detailed designs onto a special film. This film is then transferred to the garment using a heat press, where the ink adheres directly to the fabric fibers. The result is a high-quality, durable print that can capture intricate details and vibrant colors.

Essential components for DTF Printing

To successfully carry out a DTF printing project, you’ll need several key components. Here are the five essentials:

• DTF Printer: A specialized or modified inkjet printer tailored for film printing. Epson-based printers with piezoelectric printheads are commonly used in DTF applications.
• Specialized DTF inks: These inks are designed to adhere to the film and come in two types: CMYK process colors and white under-base ink.
• DTF Films: Non-adhesive films used to print the design. The film holds the ink and adhesive powder, and it dissolves under heat, leaving the print on the substrate.
• Powder adhesive: A powder that is sprinkled onto the film after printing. When heated, it melts and creates a strong bond between the print and the transfer material.
• Heat press: A machine used to transfer the design from the film to the material. The heat press melts the film and adhesive, ensuring the design is firmly attached to the substrate.

An Overview of the DTF Printing Process

Here’s a step-by-step guide to the DTF printing process:

• Design creation: Develop or modify your digital design using graphic design software like Photoshop.
• Conversion to printable format: Finalize your design and convert it into a format compatible with DTF printing.
• Printing on release film: Use a DTF printer to print the design onto a special release film. DTF printers utilize CMYK (Cyan, Magenta, Yellow, and Black) plus White inks to achieve vibrant prints.
• Applying adhesive powder: While printing, apply a unique adhesive powder to the wet ink on the film. This powder ensures that the design adheres properly to the final substrate, such as t-shirts or bags.
• Drying and melting adhesive: Pass the film through a ‘powder shaking machine’ to dry and evenly distribute the adhesive powder. This process helps in melting and setting the adhesive.
• Transferring to the final product: Position the film on the final product and use a heat press machine to transfer the design. The heat press applies specific temperature and pressure to bond the design to the fabric.
• Revealing the design: Once the product has cooled, peel away the release film to reveal the vibrant, durable design.

The result is a high-quality product with a beautifully transferred design, ready for display or sale.

The process also involves substantial electricity consumption and heat waste from curing units. Furthermore, proper disposal of leftover inks and solvents is crucial to avoid water and soil pollution.

Poor print breathability and feel

The adhesive powder used in DTF printing can affect the fabric’s breathability. The final print may feel rubbery or stiff, which can reduce comfort, especially in warmer conditions. This can make the garment less pleasant to wear compared to other printing methods that offer a softer touch and better airflow.

Comparing DTF with other printing methods

Understanding the differences between DTF printing and other popular methods can help you choose the best technique for your projects. Here’s a comparison of DTF printing with several other methods:

DTF Printing vs. DTG Printing

• • DTF Printing: Direct-to-Film (DTF) printing transfers designs onto a wide range of materials using heat. It excels at creating vivid, full-color prints, even on darker fabrics. However, DTF prints can sometimes feel stiff or heavy, and their durability may diminish after multiple washes.
  • DTG Printing: Direct-to-Garment (DTG) printing sprays ink directly onto the fabric, producing designs with a soft and natural feel. It offers high-resolution, detailed prints and retains vibrancy even after many washes. DTG is ideal for intricate designs with multiple colors, but it’s generally limited to cotton and similar fabrics.

DTF Printing vs. Screen Printing
