Background technique

UV printers are now occupying an increasingly important position in the printing market, and are widely used in various fields such as decoration building materials, advertising processing, enterprise production, oil painting industry, and personalized customization. The UV flatbed printer adopts piezoelectric inkjet printing technology, which does not directly contact the surface of the material. It relies on the voltage inside the nozzle to spray the ink in the nozzle hole to the surface of the substrate to print pictures. And the rapid curing of the ink is realized through the reaction between the light wave emitted by the UV-LED and the photosensitizer in the UV ink.

With the advancement of society and the improvement of people's aesthetic taste, the demand for decorative boards with 3D three-dimensional patterns in the printing market is increasing, which requires printing a layer of UV varnish on the color pattern layer of the substrate, and stacking patterns to Achieve 3D stereoscopic effect. At present, the common process of applying UV varnish is to apply UV varnish manually, and use a spray gun to spray UV varnish onto the decorative board, which is very technically demanding and time-consuming; the second method is to buy a UV varnish.
