UV inkjet printing, short for ultraviolet-cured digital inkjet. It is an inkjet ink technology that rapidly transforms from a liquid to a solid state under ultraviolet light irradiation.
UV Inkjet printing Performance Requirements
Viscosity: The primary performance requirement for UV-curable inks used in inkjet printing is low viscosity. Typically between 10 and 20 cPs (ink temperature is usually between 40°C and 45°C during inkjet printing). (Most printheads have onboard heaters, which can reach 60°C in many cases).
Cure Rate: The cure rate is crucial for marking and coding processes. In practical applications, printing speeds are generally between 300 and 600 ft/m. Generally, UV Printing curing technology has an advantage in speed. But the requirement for a high cure rate is related to the concentration of high-functionality prepolymers. Otherwise, high-functionality prepolymers have higher viscosity and require dilution with low-functionality monomers, which reduces the cure rate.
Flexibility: Flexibility is also a requirement for UV-curable inks used in inkjet printing. Besides, choosing suitable monofunctional monomers helps improve flexibility.
Applications of UV Printing Inks
Home Decor
UV roll-to-roll printing machine technology is widely used in the customized home furnishing industry to enrich the surface decoration of home products. For example, various patterns, such as cartoon designs and wood grain effects. I can be printed on cabinets, living room furniture, and bedroom furniture. It maks these products more personalized and aesthetically pleasing.
In the crafts and gift industry, UV printing technology is used to produce mobile phone cases, suitcases, thermos cups, ID cards, gifts, toy parts, and sporting goods. This technology allows for the printing of complex patterns and text on various materials, increasing the personalization and aesthetics of the products.
However this technology can print various patterns and text on leather, making the products more distinctive and attractive.
In the packaging industry, UV printing technology is do produce packaging boxes, wooden boxes, tin boxes, and glass bottles. This technology makes packaging more beautiful and personalized, enhancing the product’s market competitiveness.
