How TO USE: Direct-to-film ( DTF ) Printing
DTF, which stands for Direct-to-Film, is a garment printing technique that involves transferring a pre-printed design onto fabric using heat and pressure. Here’s a breakdown of the DTF printing process:
1. Design and Film Printing:
- Your design is created digitally on a computer.
- The design is then printed onto a special heat-resistant film using a specialized inkjet printer with DTF inks. These inks are designed to adhere well to the film and activate with heat during transfer.
2. Powder Application:
- Once printed, the film gets dusted with a fine, thermosetting powder (often called “hot melt powder”). This powder melts during the heat press process and creates a strong bond between the design and the fabric.
3. Curing:
- The powdered film is then cured in an oven to further activate the powder and ensure proper adhesion.
4. Heat Transfer:
- The prepared film with the design and powder is placed onto the desired garment and heat-pressed. The heat activates the powder, causing it to melt and permanently bond the design to the fabric.
5. Peeling:
- After heat pressing, the film is peeled away, leaving the design vibrantly printed on the garment.
Advantages of DTF Printing:
- Versatility: DTF can print a wide range of colors and designs, including complex details and photographs.
- Fabric Flexibility: DTF works well on a broader range of fabrics compared to DTG, including cotton, polyester blends, synthetics, and even leather (with proper adjustments).
- Durability: DTF prints are known for their good wash and wear resistance.
- Lower Setup Cost: Compared to screen printing, DTF requires a less expensive initial investment in equipment.
Disadvantages of DTF Printing:
- Multi-Step Process: DTF involves several steps compared to DTG, potentially increasing production time.
- Material Cost: The film and powder add to the overall printing cost per unit.
- Environmental Impact: The film and powder used in DTF create some additional waste compared to DTG.
In summary:
DTG and DTF printing are both great options for creating custom garments, but they cater to slightly different needs.
- DTG is ideal for on-demand printing, small batch orders, and working primarily with natural fabrics.
- DTF offers more flexibility in terms of fabric choices and potentially lower setup costs but involves a multi-step process and additional material costs.
