3.3 Ink Installation
- Fill the external ink cartridges with the appropriate DTF inks (CMYK + White).
- Ensure the white ink circulation system is active to prevent pigment settling.

4. Operating Instructions
4.1 Preparing for Print
- Design Preparation: Create or import your design in TIFF, PNG, or JPG format. Ensure the resolution is suitable for 720x1440dpi printing.
- Film Loading: Load the DTF film into the printer. Adjust the press wheels to ensure the film feeds smoothly without wrinkles.
- Ink Check: Verify that all ink cartridges have sufficient ink levels using the visual external cartridges.
4.2 Printing Process
- Send to Printer: From the RIIN software, send your prepared design to the printer.
- Monitor Printing: Observe the printing process. The printer will apply the color inks first, followed by a white ink layer.
- Powder Application: After printing, the film will move to the powder application section (if using an integrated system) where hot-melt adhesive powder is applied.
- Curing: The powdered film then proceeds to the curing unit to melt and set the adhesive.

4.3 Transferring the Design
- Once the film is cured, it is ready for transfer.
- Use a heat press to transfer the design from the film onto your desired textile (e.g., clothes, backpacks, shoes, hats).
- Follow the heat press manufacturer's instructions for temperature, pressure, and time settings.
