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 UV coating printing ink wholesalers PP, UV varnish film abrasion and adhesion is poor, especially in printing inks metal (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, the idea of ??converting to change the production process line or box to adjust the relevant aspects of the process parameters. 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 tests, I will improve the corrugated box production process methods 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 abrasion resistance and poor adhesion problems, but the high cost of screen printing UV Varnish anodized ink wholesalers, and environmental performance is less than water-based UV varnish. 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 make mirror silver ink to get the best printing results? 1, we must first understand dilute water mirror ink, printing techniques is the key, when the printing speed is slow, on the one hand, thin mirror ink will leak water, shed stencil ink, on the other hand, mirror ink is easy to absorb moisture from the air, printing obtained after a bad mirror effect, therefore, at the time of printing, ink mirror must fall in quick succession after printing network version, in order to successfully complete the printing, which is the printing side of the workpiece edge to check this rate, will give impact printing results such as blocking network, printing ink does not go on the screen slagging Orchestra. 2, printing ink mirror when the temperature and humidity of the environment is very important because of the ink on the screen is easy to do, so we can not screen in the air flow, otherwise very easy to block network, when the air humidity, the mirror effect backward, so Hardware ink manufacturers, in the screen printing, as far as possible to avoid the air flow and moisture. 3, since the ink dilute water, it should choose a high mesh screen, not only that, some rigid plastic scratch hardness should be more than 80o. 4, mirror ink stir before use to aluminum and resin mix to fully ensure the emergence of mirror effect, otherwise it will affect the produce mirror effect. 5, the network version of the tension slightly, the net transfer from the also recent and appropriate to reduce the pressure on the blade scraping, otherwise the mirror effect will undermine the formation. 6, printing machinery, the use of the knife back to Mexico is not hard aluminum or stainless steel, while the gum back blade should be used to ensure that the screen printing ink coating uniformity mirror, the mirror effect is the same. 7. Mirror mirror effect inks and dry the way, they mirror effect in terms of natural drying is less than warm dry well, and note should be consistent heating temperature and drying time, otherwise the mirror performance and color saturation will differ.
