Printing on DTF (Direct to Film) transfer film

Printing on DTF (Direct to Film) transfer film

Printing on DTF (Direct to Film) transfer film involves a specific process that differs from standard printing. Here’s a breakdown of the key steps:

1. Design Preparation

• Image Creation
  • Create your design using graphic design software.
  • Ensure the image is high-resolution for optimal print quality.
• Mirroring
  • Crucially, mirror your image before printing. This is because the design will be transferred in reverse onto the fabric.
• White Underbase
  • DTF printing often involves printing a layer of white ink behind the color image. This is essential for vibrant colors, especially on dark fabrics. Specialized DTF software handles this.

2. Printing

• DTF Printer
  • You’ll need a dedicated DTF printer or a modified inkjet printer that uses DTF inks.
• DTF Ink
  • Use specialized DTF inks designed for this process. These inks adhere well to the film and fabric.
• DTF Film Loading
  • Load the DTF film into the printer, ensuring the correct side is facing up. Typically, the matte side is the print side.
• Printing Process
  • The printer will first lay down the white ink layer (if applicable), followed by the color inks.
  • DTF printing software is a very important part of the process, as it controls the white ink layer.

3. Powder Application

• DTF Powder
  • While the ink is still wet, apply a specialized DTF hot-melt powder evenly over the printed design.
• Powder Adhesion
  • The powder will adhere to the wet ink.
• Excess Removal
  • Carefully remove any excess powder by gently shaking or tapping the film.

4. Powder Curing

• Heat Curing
  • The powder needs to be cured (melted) to create an adhesive layer. This can be done using:
    • A DTF curing oven.
    • A heat press (hovering over the film).
• Curing Process
  • The heat melts the powder, creating a glue-like layer that will bond the ink to the fabric.

5. Transferring to Fabric

• Heat Pressing
  • Place the prepared DTF transfer film onto the fabric.
  • Use a heat press to apply heat and pressure, transferring the design onto the fabric.
• Peeling
  • Depending on the type of DTF film (hot peel or cold peel), either peel off the film immediately while hot or wait for it to cool down.

Key Considerations

• Software: DTF printing software is vital for accurate color reproduction and white ink management.
• Equipment: High-quality DTF printers, inks, and heat presses are essential for professional results.
• Ventilation: DTF printing can produce fumes, so ensure proper ventilation.
