General knowledge of the application of UV printing inks

the research on thermoforming UV ink is in full swing. This kind of ink has good adhesion and flexibility, and can be stretched in thermal forming, and can stretch 8 inches or more in vacuum forming. The formulation of thermoformed UV ink has been improved, which can be thermally bent, stretched and other post-processing on a variety of substrates, such as styrene, polycarbonate, acrylic resin, PETG (glycol modified PET), PVC and some metals

the in-depth study and understanding of the reaction mechanism of UV ink with thick ink layer to photoinitiators have enabled ink formula designers to deploy more special UV inks, including ink products with high pigment content that can form thick ink layers. Now, printers can choose 60 lines/inch thick, 300 m or more thick photosensitive glue silk to print. Alternative thick ink UV ink products include thixotropic coatings and inks that can produce relief printing effects. This kind of ink is expected to have a significant increase in application

the high ductility resin and monomer used in the preparation of thermoformed UV ink can also be used to configure a new type of thick ink layer UV ink forming substrate liquid ink, which includes a formula that can be called liquid substrate material. In other words, this ink is both an imaging material and a printing material after curing. According to different ink formulations, pressure-sensitive or electrostatic adsorption images can be generated after printing. This printing method saves materials and saves material and die-cutting costs, but also reduces the turnaround time

another product that extends from the thick ink layer UV ink technology and adopts microcomputer closed-loop control is magnetic UV ink. This kind of ink can be printed on a variety of substrate materials to make it magnetic, but this kind of ink does not turn the image into a real magnet, but can fix the printed image through the magnetic surface after the ink solidifies. This kind of ink is suitable for printing images that often need to be replaced, such as those in newsstands, shelves, combined mold displays, etc. Special effect UV ink thick ink layer UV ink technology has driven the development of several new inks with special effects. Flash UV ink with large particles of luminous particles can produce a sparkling effect on the printed pattern. This kind of ink requires coarse screen silk printing, so that the flashing particles can pass through. Another newly developed ink is a long-term luminous ink, which can shine for more than 14 hours. Other UV ink formulations use pearl like, spark like, or metallic particles in a range of colors, based on a rough classification of the substrate. Inks with high pigment content enable printers to consider printing on dark substrates, which can ensure better color hiding power

fire resistant UV ink another research hotspot of UV printing ink technology is fire-resistant UV ink. This kind of ink is proposed for some consumers to pay attention to the safety of printed matter, and the ink and substrate manufacturers work together to study solutions. Although UV ink has a relatively high flash point, once the combustion limit temperature is exceeded, UV ink will also decompose and burn. There are two ways to slow down the combustion of UV ink because of the large number of small and micro enterprises in China's experimental machine industry. One is to use inhibitors in the ink to prevent combustion, reduce or even eliminate flames. Another method is to imitate the foaming fire retardant coating to design UV ink formula. Foaming fire retardant coating inspects the damage and deformation of two materials of low carbon cast iron. Under the action of flame or high temperature, the coating foams and carbonizes violently, isolating oxygen, and then preventing combustion and suppressing flame. It should be borne in mind that fire-resistant UV ink alone cannot completely prevent fire, and the expansion performance of substrate and the ability to suppress flame are equally important

new application of UV printing inks recent technological innovations have enabled ink manufacturers to produce UV inks with good adhesion, durability, flexibility and water resistance. The latest development of UV ink technology has had an important impact on the following markets and application fields. In the past, only multi-purpose pop inks showed good adhesion on a variety of substrates, including paper, paperboard, styrene, stretched polyvinyl chloride, and even some polyolefins that are difficult to adhere. But a few years ago, the emergence of one component UV ink completely changed this situation. This kind of ink can adhere well to polyolefin materials (PE, PP) and has good performance characteristics, such as excellent ink film flexibility and water resistance in label printing and other fields. This new ink eliminates the use of additives, reduces the waste of similar two-component inks, and can also reduce ink inventory and improve economic benefits

application of UV printing ink technology on containers the greatest progress should be made in container printing. In the past, a variety of additives and ink systems were needed to adapt to different types of plastic containers, but now plastic containers made of HDPE, LDPE, pet, PVC, PP and other materials can be decorated with single component ink without additives. These inks can provide better hiding power, stronger resistance to chemical solvents, and also eliminate the use of additives and catalysts

application in hygroscopic plastics the development of multifunctional monomers is one of the latest developments in UV ink technology. Ink manufacturers are using it to solve the problem of printing hygroscopic plastics, such as polyethylene labels and HDPE materials. These substrates are easy to absorb moisture, and water vapor forms a subtle barrier layer between the ink and the substrate surface, affecting the adhesion of the ink. Therefore, the ink layer on these materials is easy to wear and peel off. The ink prepared with this new multifunctional monomer greatly improves its water resistance on hygroscopic materials, with faster curing speed, higher gloss and firmer ink layer, and the ink layer is almost completely water-resistant

with the continuous development of raw materials, the development of UV printing inks seems to be unable to see how successful UV curing products will be in the future, and how many robot products have been successfully developed and used in various processes of the tire industry. In the early years, UV inks added a variety of additives to improve performance, and printers had to play the role of chemists in order to achieve good ink performance. But today, ink manufacturers can develop products according to customer needs and adopt more advanced technologies in ink production. Raw material suppliers will also develop raw materials according to the needs of ink designers. Unlike at the beginning, there were only a few raw materials for designers to choose
