Complete Workflow of DTF Printing: From RIP Software to Film, Ink & Powder

To understand why Direct-to-Film (DTF) printing is called a revolution in textile printing, follow the process from design creation to heat and pressure transfer. The process begins with preparing the design for printing. A specialized Raster Image Processor, or the RIP software, plays a crucial role in the preparation.

Let’s learn the workflow to understand each step in detail

1. Design Preparation

Produce a high-quality digital image of at least 300 dpi using a graphic design software. You can use Adobe Photoshop, Illustrator, or any other tool you are comfortable working with.

Mirror the image: Flip the image horizontally so it prints correctly on the film. It is necessary to ensure a smooth transfer with all details clearly visible in the final print.

Process with the software: The software controls the operation by providing the finishing touch to the design. It does the following jobs:

• Creates a white ink underbase behind the print. Colors appear vibrant and opaque, especially on dark-colored fabrics.

• Ensures accurate color production by controlling color profiles.

• Manages ink flow, dot placement, and print size.

Most DTF printers come with built-in software. You can also buy third-party software for your DTF machine. Its role is crucial in enhancing the final design.

2. Design Printing

The printer starts processing the design for printing. It is first printed on a specialised DTF film, specifically PET (polyethene terephthalate) film. 

Print onto the film: The film is placed in the printer. The colors flowing from the machine produce a beautiful design on it. Finally, the print is layered with a specific white DTF ink. This white layer provides a strong foundation for the adhesive. 

Apply DTF powder: A hot-melt adhesive powder is sprinkled over the colors while they are still wet. The wet colors soak the powder well. The excess adhesive on the non-print areas is gently shaken or vacuumed to prevent it from going to the print. 

Cure the adhesive: The film is then heated to melt the adhesive into a fully cured and transfer-ready layer. You can use a curing oven for this process. The adhesive requires a specific temperature to cure into the colors.

3. Design Transfer to Garment

It is the final step involving the transfer of the design under specific heat and pressure settings.

Pre-press the garment: The garment is pressed for 10 seconds to remove whatever moisture or wrinkles it has. The pressing smoothens the textile for design transfer.

Press the design: The design is pressed onto the garment under a heat-press machine. The machine melts the design under high heat and presses the design onto the garment. The transfer takes a few seconds to complete.

Here, it is necessary to mention that heat and pressure settings are different for textiles. You choose the settings after considering the strength of the fabric and the complexity of the design.

Peel the DTF film: Finally, the film is peeled either hot or cold from the garment. Peeling the film exposes the design. It looks vibrant. The garment is then sent for packing.
