Direct-to-film printing

Uptake of DTF began in the early 2020s among small and mid-size providers, followed by the introduction of dedicated DTF devices by major equipment manufacturers.^[1][2]

In DTF, the image is typically mirrored and the CMYK layers are printed on PET film, followed by white ink to create an opaque backing. While still tacky, a fine thermoplastic polyurethane hot-melt powder is applied to the printed areas and fused. The transfer is then heat-pressed onto the garment and the carrier film is peeled.^[1][3]

DTF transfers can be produced on modified direct-to-garment devices or on dedicated roll-to-roll systems that integrate the printer with a powder shaker and curing unit. Once cured, transfer films can be stored and used later in the press stage, decoupling printing from garment finishing.^[3][4]
