[UV Adhesion] How to Improve the Adhesion of the UV Ink

The use rate of UV inks in the printing industry is getting higher and higher. However, when printing some materials with UV tablet printers, is there any problem that the UV ink has low adhesion to the bottom material because of the instantaneous drying of the UV ink? Below teach you how to improve the adhesion of the UV ink to the bottom material. 1. Electric halo treatment Electric halo treatment is a method that can effectively improve the adhesion of the UV ink. The positive and negative poles of the electro -halo device are grounded and induced electric air nozzles, respectively. With high -energy acceleration acceleration to the positive electrode, this can enhance the ability to combine with ink, improve the purpose of the ink layer attachment,. 2. In many cases, the UV ink attachment force promotion agent will increase the base material with alcohol will increase the adhesion of the UV ink on the bottom material. If the attachment of UV ink is very poor, or the product's requirements for the attachment of the UV ink are relatively high, then you can consider using the primer/UV ink adhesion to promote UV ink attachment. Third, UV ink solidification is generally speaking. In the case that UV inks are not completely solidified, we can observe the phenomenon of poorly attached UV inks on non -absorbing substrates. Increasing the degree of solidification of UV inks can start from the following aspects: 1. Increase the power of UV -optical curing lights. 2. Reduce printing speed. 3. Extend the time of solidification. 4. Check whether the UV light and its accessories work normally. 5. Reduce the thickness of the ink layer. Fourth, other methods heating: In the screen printing industry, before printing the difficulty attached material, it is recommended to heat the bottom material before UV curing. After using near-infrared light or far infrared light for 15-90 seconds, the attachment of the UV ink on the bottom material can be strengthened.
