UV Inks

UV inks are the core consumables for UV inkjet printing systems, essentially being eco-friendly inks that cure instantly upon exposure to ultraviolet light. These UV inks undergo photopolymerization upon irradiation by UV-LED lamps after jetting, transforming instantly from liquid to solid ink layers, achieving an "instant-drying" effect without the need for subsequent drying processes. UV inks are generally classified into three types—rigid inks, flexible inks, and neutral inks—to accommodate substrates with different physical properties. Rigid inks, which form high-hardness, high-adhesion ink layers after curing, are suitable for hard surfaces such as glass, metal, and ceramics. Flexible inks offer excellent elongation and bending resistance, making them ideal for leather, soft films, and bendable materials. Neutral inks balance hardness and toughness, adapting to mixed-material scenarios. High-quality UV inks should possess characteristics including saturated colors, wide color gamut, excellent adhesion, strong weather resistance, and low odor. Users can select or customize formulations based on actual printing substrates to achieve optimal adhesion and durability.
