Process
DTF
Direct-to-film transfer printing process used to produce full-color heat-applied graphics for apparel decoration.
Definition
DTF stands for direct-to-film. The process prints CMYK ink and a white underbase onto a PET carrier film, then applies hot melt polyamide adhesive powder to the wet ink. The film is cured in a low-heat oven to set the adhesive into a continuous layer. Decorators apply the finished transfer to fabric using a heat press at 285 to 325 degrees F for 10 to 20 seconds with medium-to-firm pressure. DTF bonds to cotton, polyester, blends, fleece, denim, and most fabric types without weeding or garment pretreatment. The white underbase enables full-color decoration on dark garments without separate plates or screens. Long Island DTF Printing produces DTF transfers at $0.06 per square inch flat rate with no minimums.
