A UV sticker (or UV DTF sticker) is a durable, vibrant decal made with special UV-curable inks that are instantly hardened (cured) by ultraviolet light, allowing for detailed designs to be transferred onto almost any hard surface like glass, metal, or plastic, offering waterproof, scratch-resistant, and fade-proof results for customization. These differ from traditional stickers by using a Direct-to-Film (DTF) process where designs are printed on a film and then transferred with an adhesive layer, making them ideal for curved items and complex designs without heat presses
