Direct-to-film (DTF) printing has become the most versatile textile personalization technique: cotton, polyester, silk, synthetic fibers, light or dark materials—all without pretreatment. This guide presents all the necessary equipment, the process steps, and the advantages of the technique.
Understanding the technique
Direct-to-film (DTF) is a digital textile printing technique that involves printing a design onto a PET film, coating it with a heat-fusible powder, and then transferring it onto fabric using a heat press. The result is a flexible, wash-resistant transfer that can be applied to virtually any textile—cotton, polyester, silk, synthetic fibers, light or dark fabrics.
Unlike traditional sublimation, which is limited to white polyester, or DTG, which requires pretreatment, DTF requires no pretreatment and is suitable for all types of substrates. It is currently the most versatile textile printing solution on the market.
Equipment
One of the advantages of DTF is that it doesn't require excessive investment to get started. Here are the 8 components of a complete DTF system.
Called "modified DTF printers," they are equipped with six ink tanks : CMYK in the standard tanks, and DTF white in the LC and LM tanks. The feed rollers are removed to prevent liners on the white layer. Models based on the Epson L1800 are among the most common.

White ink is the key component: it is deposited first on the film to create an opaque background onto which the colors are printed. Créadhésif offers DTF inks renowned for their excellent results on both light and dark textiles, with optimal white density and controlled consumption.

→ See DTF hot melt powdersTheautomatic powder agitator ensures uniform application and removes excess powder. The curing oven melts the powder at 160–170°C for 2 to 5 minutes. Alternatively, a heat press can be used in non-contact mode (4 to 7 mm gap between the film and the platen).
The RIP software manages color profiling, ink levels, droplet size , and the printing order of the layers (colors then white). It must be able to handle CMYK colors and white ink simultaneously—this is what determines the final quality of the transfer.
The heat press is used in two stages: first, for melting the powder (in non-contact mode), and then for the final transfer at 160–170°C for 15 to 20 seconds. A platen of at least 38×38 cm is recommended for an A3-sized T-shirt. The Stahls DTG/DTF heat press is particularly well-suited for this purpose.

From digital file to finished t-shirt, here is the complete process of a DTF production.
Mirror image printing on PET film — colors first, then white on top. The RIP software manages the order and densities.
Apply the hot melt powder evenly to the still-wet print. Carefully remove any excess – by hand or with an automatic stirrer.
Place in a curing oven or under a heat press in non-contact mode (space 4–7 mm). Temperature: 160 to 170°C for 2 to 5 minutes.
Press the fabric alone for 2 to 5 seconds to flatten it and remove residual moisture. This step is essential for optimal transfer.
The film is placed on the fabric in the heat press. Transfer at 160–170°C for 15 to 20 seconds. This is the curing stage — the powder permanently bonds the image to the fibers.
Allow the fabric to cool to room temperature before peeling off the film. Premature peeling can affect the finish. See also the hot peeling instructions for your specific film type.
Final pressing of the fabric for 10 to 15 seconds to improve resistance to washing and rubbing. This step is optional but highly recommended for a professional finish.

Frequently Asked Questions
No. DTF printing requires specific pigment inks (including an opaque white ink) that are incompatible with dye-sublimation printers. The printer must be modified to accommodate six DTF tanks. If you want to personalize cotton without investing in a DTF printer, our ready-to-press DTF transfer service is the most affordable solution.
A hot peel is removed immediately after pressing, while still hot. A cold peel must cool to room temperature before being peeled. Cold peel is more forgiving and often preferred by beginners. Both produce excellent results—the choice depends on your production workflow and the type of substrate.
Yes. With proper pressing and a 10-15 second post-press, DTF transfers offer excellent wash resistance. Wash at 30–40°C, inside out, without fabric softener. The quality of the hot melt powder and adherence to the pressing parameters are the two key factors in durability.
Absolutely. Créadhésif offers a DTF printing service : you send us your file, we print and ship your heat transfers ready to press, starting at €0.16 excluding VAT per unit (5x5 cm label), in A4, A3, A2, 56x100 cm and 56x200 cm formats. 24-hour express shipping is available. All you need is a heat press.
Traditional sublimation only works on white or light-colored polyester —the inks sublimate into the fibers without a visible intermediate layer. Direct-to-Fly (DTF) printing works on all textiles (cotton, polyester, silk, dark colors) using a transfer film with a heat-fusible powder. Sublimation provides an invisible feel; DTF offers a slightly noticeable but very light touch. In terms of color vibrancy, sublimation is slightly superior. See our sublimation paper guide for cotton alternatives.
