What Does DTF Stand For in Transfers?

DTF, short for Direct-to-Film, refers to a printing technique where ink is directly transferred onto a specialized film. This film is subsequently applied to a range of surfaces, notably textiles such as T-shirts. Characterized by its ability to deliver high-resolution, full-color prints, DTF printing stands out for producing detailed, vivid designs. It's celebrated for its adaptability and capacity to render complex images with sharpness and accuracy.

Key elements and factors to consider when adopting DTF (Direct-to-Film) printing include:
