[Print] Talking About the Application of UVLED in UV Convex Printing Printing

The convex printing will be raised in the place where the printing version is made, and the place where there is no picture and text will be depressed. When the machine works, the rubber roller with ink on the surface is rolled over the printing surface. A uniform ink layer, while the blank part is not dipped in ink. Under the influence of the pressure agency, the ink is transferred to the surface of the printed object. Most of the convex printing printing currently uses UV processes. UV optical solidification is performed immediately after transfer, which greatly improves printing efficiency. In recent years, with the popularity of UVLED, the UVLED facial light sources are increasing as a cured light source, and the corresponding ink is LED special ink, such as UV161LED. Using UVLED as a curing light source can be accurately controlled, that is, use it, and more energy saving. And UVLED is a cold light source, which is controlled by the temperature rise of the irradiated objects in the light. Many incompetent materials such as PVC are also applied. UVLED face light sources generally use the wavelength of 385nm or 395nm, the same ink, different printing processes, different print thickness, and the wavelengths used are different. If we are thinner, we will choose 385nm, and get better drying in a short time optical curing. When it is thicker, we will choose 395nm, because the wavelength is long and the light penetration is better, so as to obtain a better bonding effect. In addition, in order to increase the liquidity and adhesion of the ink, the two additives are added to the ink raw liquid in the ink raw liquid in a certain proportion in the convex printing. Tianhuilx-S30060 facial light source (385) Tianhui's UVLED face light source uses imported UVLED lamp beads, high-quality constant stream sources, and excellent heat dissipation design. It has the advantages of structural compactness, high reliability, and high stability. Praise.
