DTF Printers

What is DTF (Direct-to-film)?

Direct-to-Film (DTF) printing is a method used to transfer designs or images onto various textiles, most commonly clothing. The process involves printing the design onto a PET film, which is then transferred onto the desired material using heat and pressure. DTF printing is often used in garment decoration, promotional products, and other applications where high-quality, detailed prints are desired.

Design Preparation

The design or image to be printed is prepared digitally using graphic design software (Adobe Illustrator, CorelDRAW etc.). This can include artwork, logos, text, or any other desired graphics. The design is then converted into a format compatible with the DTF printer. The design must be run through a RIP software (Print Factory) to make the compatible printing file.

Film Printing

The prepared design is printed onto a PET film using a DTF printer. It is printed with the design in reverse and the colours are typically coated with a top layer of white to make the image appear more vibrantly on fabrics. DTF printers are equipped with specialized printheads and inks optimized for this production process.

Film Coating

After printing, a layer of adhesive hot melt powder is applied to the printed film using a coating machine. This coating must have the correct amount of powder applied so a shaker is often required to get rid of excess powder. The print is then heated to high temperatures to melt the adhesive powder and seal the design.

Film Transfer

The printed and coated film is carefully placed onto the surface of the substrate, ensuring proper alignment of the design. The film is then pressed onto the fabric using a heat press. The high temperatures and pressure cause the hot melt powder to adhere the design to the material.

Cooling and Peeling

After the transfer process is complete and the substrate is allowed to cool down this allows the adhesive to solidify and bond the design securely to the surface. Once cooled, the film is carefully peeled away from the substrate, leaving behind the printed design.

Some DTF films (like ours!) can be peeled instantly without needing to wait for it to cool down.
