Regarding the customer's questions about UV inkjet printer inks, Arnoldjet gives this answer_Identification accessory products

Compared with traditional inks, UV inkjet printer inks have the advantages of high efficiency, low cost, and environmental protection. However, due to the lack of mature protection technology in the UV ink printing process in the past, and the high cost, the promotion and application of UV inkjet printer inks have been largely restricted. However, in recent years, the improvement of environmental protection requirements, the maturity of protection technology, and the increase of market revenue have prompted more and more applications of UV inks in printing. Customers who are unfamiliar with inkjet coding may have questions at the beginning, so let's take a look at it; what happens if the ink of the UV inkjet printer is over-cured? One theory is that when the surface of the ink is exposed to too much ultraviolet light, it will become harder and harder. When the operator prints another ink on this hardened ink film and dries it for the second time, the adhesion between the upper layer of ink and the lower layer of ink will become very poor. The over-cured ink film is not only inferior in flexibility, but also prone to surface embrittlement. How to ensure that the UV inkjet printer ink can be properly cured? The curing of the ink film when it passes through the curing unit for the first time is very important. Proper curing can minimize the problems of substrate deformation, over-curing, re-wetting and insufficient curing, and can optimize the adhesion between ink and humor or between coating and coating. In order to test the curing efficiency of UV ink, we can start printing at the lowest speed allowed by the substrate first, and cure the first printed sample. Then, set the power of the curing lamp to the value specified by the ink manufacturer. When dealing with colors that are not easy to cure, such as black and white, we can also increase the parameters of the curing lamp appropriately. A question that is often asked is that it is possible to cure the ink of the UV inkjet printer without replacing the UV lamp with a nitrogen curing unit? The curing system that uses nitrogen to cure printed matter has appeared as early as ten years ago. These systems are mainly used in the curing process of textiles and membrane switches. The reason why people use nitrogen to replace oxygen is mainly because oxygen inhibits the curing of ink. However, because the light from the bulb in this type of system is very limited, the curing effect for UV inks or UV inkjet printers is not very good.
