Introduction
DTF film is transforming the custom printing industry. It allows high-quality prints on various fabrics, including cotton, polyester, and blends. Unlike traditional methods, DTF printing is cost-effective, durable, and does not require fabric pretreatment.
In this guide, you’ll learn everything about DTF film, from its history and working process to equipment, troubleshooting, and business potential. Let’s dive in!
What is DTF Film?
DTF (Direct-to-Film) film is a special PET (polyethylene terephthalate) sheet used in DTF printing. It holds ink and adhesive powder, which is later transferred to fabric using heat and pressure. This process enables vibrant, long-lasting designs on various materials.
How DTF Printing Works
DTF printing follows these key steps:
- Design Preparation – Create a high-resolution design and mirror it before printing.
- Printing on DTF Film – Print CMYK colors first, followed by a layer of white ink.
- Applying DTF Powder – Sprinkle adhesive powder on wet ink and remove excess.
- Curing the Powder – Heat the film at 320°F (160°C) for 2 minutes to bond the ink and powder.
- Transferring to Fabric – Press the cured film onto fabric using a heat press at 300-325°F.
- Peeling the Film – Peel the film either hot or cold, depending on the type.
History & Evolution of DTF Printing
DTF printing is a relatively new technology, emerging as an alternative to DTG (Direct-to-Garment) and sublimation. Initially used for promotional apparel, it quickly became a go-to for businesses due to its versatility and lower setup cost.
Comparison with Other Printing Methods
| Feature | DTF Printing | DTG Printing | Sublimation | Screen Printing |
| Fabric Compatibility | All fabrics | Cotton only | Polyester only | Mostly cotton |
| Durability | High | Medium | High (on polyester) | High |
| Cost | Low | High | Moderate | High |
| Wash Resistance | High | Medium | High | High |
| Setup Time | Quick | Time-consuming | Quick | Long |
Types of DTF Film: Hot Peel vs. Cold Peel
- Hot Peel DTF Film – Peeled immediately after pressing. Provides a soft feel and saves time.
- Cold Peel DTF Film – Peeled after cooling. Produces a slightly glossy, durable finish.
Choosing the Right DTF Film
Factors to consider when selecting DTF film:
- Thickness: 75-micron for light fabrics, 90-micron for textured materials.
- Finish: Glossy for vibrant colors, matte to reduce glare.
- Adhesion Quality: High-quality films ensure strong transfers.
DTF Printing Process: Step-by-Step Guide
- Prepare Design – Use 300 DPI images and mirror before printing.
- Print on DTF Film – Load the coated side into the printer.
- Apply Adhesive Powder – Evenly coat the design and shake off excess.
- Cure the Powder – Heat in an oven or heat press.
- Transfer to Fabric – Press at 320°F (160°C) for 10-15 seconds.
- Peel the Film – Hot or cold, based on the type.
Essential Equipment for DTF Printing
- DTF Printer – Epson L1800 (budget) or Epson SureColor P600 (pro).
- DTF Ink – CMYK and white pigments for vibrant results.
- DTF Powder – Ensures strong adhesion.
- Heat Press Machine – Transfers the design to fabric.
- Curing Oven or Heat Press – For powder curing.
