UV Braille Crystal Clear (Colorful) Varnish Short UV Braille oil, also known as marble ink. It is mainly composed of highly concentrated, highly transparent, high-rising UV-cured oil that does not turn yellow after curing. The main advantages are fast drying, wear-resisting, environmental protection, crystal clear, non-yellowing, and smooth feel. After the screen printing process, the printed part has a stand-up effect irrespective of its visual and feel. The thickness can reach as high as 2mm. After drying, the printing area is like a three-dimensional crystal. Engraving, Epoxy-like effect. Such as mixed colorful powder, magic color film printed together, the effect is like a colorful gem-like beautiful, can be decorated with clothes, flowers, bird wings, leaves, lines, comics and other patterns. It has been widely used in packaging, calendars, greeting cards, books, business cards, and other papers in developed coastal printing areas, including matte film substrates. UV drying conditions above 80W/CM.
Its production process mainly pays attention to the following points:
1. Choose a good UV Braille crystal varnish. Must choose high transparency, high concentration, no blistering after printing, Braille varnish that does not turn yellow after curing. Adhesion is also better.
2. Screen production. First, the screen tension should be between 20-21N. The number of mesh yarns is suitable for between 25 mesh and 150 mesh. If you want to mix colorful powder printing, you should choose between 25 mesh and 80 mesh gauze (mainly considering whether the color powder can pass through the gauze and the size of the target mesh). The higher the height requirement of UV Braille, the smaller the mesh size, and the greater the mesh size. Also, thickening the thickness of the photosensitive adhesive, the operating procedures: coated photosensitive adhesive - drying - photosensitive adhesive - drying - printing.
3. Printing operation. The hardness of the scraper is 75-80. Sharp corners remain sharp. Squeegee angle is selected at 45. Printing pressure cannot be too great. It is only necessary to shave the convex ink on the screen. Because the pressure is considered to be slightly smaller than the normal screen printing, the distance between the screen and the ink should just be printed on the substrate. If the net distance is too large and the pressure of the squeegee is too high, it is easy to press the ink printed on the substrate back onto the screen plate. In this way, the ink thickness and surface smoothness effect of the printed ink are poor.
