How to improve the wear resistance and adhesion of UV varnish? UV printing inks are often used to work in a printing material, and there is a surface finishing process called UV coating is achieved by means of UV inks. Today we'll talk about UV coating. Box printing enterprises (especially export business in Japan and Europe and other countries and regions, box printing companies) often encounter such problems: After printing UV coating, UV varnish coating abrasion and adhesion is poor, especially the use of metallic inks printed materials (gold or silver ink ink) printing with UV coating and then when this phenomenon is particularly prominent. Under normal circumstances, the box printing companies tend to solve this problem by replacing the UV varnish. In fact, we should not only be limited to the idea of ??replacing the UV varnish, but should divergent thinking anodized ink wholesalers, the idea of ??converting to change the box to adjust the production process line or process parameters related aspects. Conventional corrugated box production process route is: ordinary printing plate and cutter → → → over the UV Primer UV mounted corrugated surface oil → → → die-gluing. After several test methods PP ink wholesalers, I will improve the corrugated box production process are summarized below. (1) plate and cutter → UV inks + UV coating line. Must adopt UV test proved that the production process can be greatly enhanced UV varnish on metal wear resistance and adhesion of UV inks, UV metallic inks but relatively rare in the market, require special customization, expensive, and printing presses. In general, most small businesses do not have UV box printing presses, so this part of the production process only applies to box printing business, general promotion of little significance. (2) ordinary printing plate and cutter → → screen printing UV coating. This production process can be resolved UV varnish on the metallic ink problem of poor wear resistance and adhesion of the ink, but the high cost of screen printing UV varnish, UV and water-based varnish inferior environmental performance. In addition, many companies are not fully automatic folding carton printing screen printer, only the lower productivity of semi-automatic screen printing machine, so this production process only applies to part of the box printing business, not worth popularized. How to calculate the amount of screen printing inks can be used two ways to count, you can try printing the first estimation method, such as using 1KG how much ink can be printed, plus loss. The second can be precise calculation method is based on the pattern you printed product size, ink thickness or mesh wire diameter plus the proportion of volatile ink to calculate, but this is too much trouble, general plant usually are former . I installed the years for various printers and ink color matching system design, field plating ink in the ink color wholesalers, although not consider themselves experts, but they dare admit ink color system is very knowledgeable. But nine months ago, when I as usual client installation and design color ink system for customers suddenly asked a very puzzled question: "How do we calculate the actual production to be ready when the ink amount if the amount of preparation? Too many, in the production of a large number of the remaining waste ink often a waste costs, increased waste ink inventory. If the budget is too small, the staff have to be reconstituted, even down to wait, which affects the production schedule. glass ink wholesalers, Hibernia Granville printing equipment (certified), the ink supplied by Dongguan Heng Heng Li Yawei printing equipment materials firm.
