UV white ink also differs from traditional solvent inks in its usage. Since UV ink can be combined with white ink, it enables the printing of a captivating relief effect. This phenomenon arises from the accumulation of white ink creating a relief effect, which is subsequently followed by the application of colored UV ink. The resulting embossed effect can be obtained through a single printing process. Conversely, other solvent inks cannot be blended with white ink, hindering the ability to produce a relief effect. Additionally, the diameter of pigment particles in UV ink is less than 1 micron, it does not contain volatile organic solvents, boasts ultra-low viscosity, and lacks an irritating odor, ensuring that the ink will not block the nozzle during printing. According to professional tests, UV ink has been subjected to high-temperature conditions for six months, showcasing very satisfactory results with no pigment aggregation, sinking, delamination, or other abnormalities.

Currently, UV inks dominate the packaging digital printing market. This dominance is primarily due to the high stability of UV ink, as it does not dry out due to exposure to air. Therefore, even when the print head is used intermittently, there is no need to worry about the inkjet head drying out or ink clogging. Furthermore, UV LED curing lamps possess a compact structure and outstanding drying effects, which can cure printed images almost instantaneously. The cured images are highly durable, making UV inkjet suitable for both industrial printing and high-fidelity image printing. For high-fidelity printing, UV inkjet offers two valuable add-ons: the ability to print on smooth surfaces and the aptitude to print on textured surfaces.
