While preparing the image for print is particularly important, applying the hot-melt adhesive is equally so with DTF; it uses a hot-melt powder made of polyurethane resin ground into adhesive powder. This is the integral process of the entire DTF printing process. While there are no harmful emissions, the powder adhesive is exceptionally fine and can generate dust, so it’s important to wear respiratory protection when working with the powder. It’s also best to keep the inkjet printer at a safe distance from the powder coating process to keep adhesive dust from penetrating the sensitive parts inside the printer.
