✅ What Is a DTF Ink Printer?

A Ink printer is a specialized printer (often modified from flatbed or wide-format models) that prints full‑color designs onto PET film using DTF ink—including a white ink layer. After printing, adhesive powder is applied, and the sheet is heat-cured. Finally, the design is transferred onto fabric via heat press. This method allows vibrant, durable prints on almost any material.
🧼 It works on cotton, polyester, blends, nylon, leather, and more—without pretreatment.

🎯 Benefits of Using a DTF  Printer

• Full‑Color Printing with White Ink: Achieve vivid and accurate colors, even on dark fabrics.

• High Durability: Prints withstand washing and retain integrity over time.

• Flexible Fabric Compatibility: Unlike DTG or sublimation, DTF works on a broader range of materials.

• Low Setup Cost: Ideal for small runs or print-on-demand operations without needing screens or pretreatment.

• Scalable Workflow: Gang sheets allow efficient batch prints and cost savings.

🧰 DTF Printer Setup & Workflow

1. Choose the Right Printer Base

Select a printer compatible with refillable ink systems—often models from Epson or Mimaki modified for DTF use.

2. Install DTF Ink

Refillable ink tanks allow for CMYK + white ink. White ink must be recirculated to prevent settling.

3. Prepare Design Files

Use high-resolution artwork (300 DPI), export as PNG with transparency or vector formats. Set up a white layer under colors for dark garments.

4. Print onto Film

Load PET film, set the software to print with white ink backing. Ensure proper ICC profiles and color calibration for accurate output.

5. Apply Adhesive Powder

While ink is still wet, sprinkle adhesive powder evenly then heat-cure at approximately 160–180 °C to bond it to the film.

6. Curing & Pressing

After curing, let the film cool. Cut out designs or gang sheets and apply with heat press at 300–325 °F for 10–15 seconds. Choose between hot and cold peel types depending on the film and fabric.
