In this lesson (Topic 4 of the American DTF Academy), we break down the three core consumables that make Direct-to-Film (DTF) printing possible: transfer films, inks, and adhesive powder. Mastering these materials is key to producing vibrant, long-lasting prints with professional results.
DTF Transfer Films
-
What They Are: PET-based films with a special coating designed to hold ink and release it cleanly onto fabric.
-
Thickness: Commonly 75 μm (standard use) and 100 μm (heavy-duty, high durability).
-
Peel Options:
-
Hot Peel → Peel immediately after pressing (faster, good for production).
-
Cold Peel → Peel after cooling (slower, but stronger adhesion and sharper details).
-
-
Finish: Matte (durable, smooth) or Glossy (shiny, vibrant).
-
Why It Matters: The quality of the film directly affects color vibrancy, detail sharpness, and how easily the transfer releases.
DTF Inks (CMYK + White)
-
Composition: Water-based pigment inks engineered for DTF printers.
-
White Ink: The foundation layer that makes colors pop on dark fabrics—more prone to settling, so it requires regular shaking and proper circulation.
-
CMYK Inks: Provide vibrant, accurate colors with smooth flow through printheads.
-
Quality Impact: Premium inks prevent clogging, deliver brighter prints, and extend wash durability.
-
Trusted Brands: STS, Image Armor, Kodak, and DuPont Artistri are among the most reliable options.
DTF Adhesive Powder (Hot-Melt Powder)
-
Purpose: Fuses the ink to the fabric during heat pressing, ensuring durability and flexibility.
-
Types: Different grain sizes (fine, medium, coarse) for different fabrics and finishes.
-
Best Practices: Apply evenly and remove excess powder to avoid rough edges or speckling.
Storage & Handling Best Practices
-
Keep consumables in a cool, dry environment.
-
Shake white ink regularly to prevent pigment settling.
-
Store films flat to avoid warping.
-
Seal powders tightly to protect against moisture.
Conclusion
The quality of your films, inks, and powders defines the quality of your final print. By investing in reliable consumables and following proper storage and handling practices, you’ll ensure vibrant colors, strong adhesion, and long-lasting results—every time.
