UV inks on the ordinary (UV) coating
Network connection. But hinder the reaction of oxygen. For the cationic curing coatings, UV 111 eggs JOURNAL - Ba: I 【! Man ■!

(UV) light induced ion formation, the formation of hardened chain reaction. The continuity of the cure, although the cure slower, but can be completely cured. Although the water suppression reaction, cationic UV curing (UV) coating the coating method used for food packaging, because they do not smell and hardened completely. Our test focused on the chemical-based curing ultraviolet (UV) coating coating. Increase the amount of UV coatings can improve the gloss, the effect is not as good as a good increase in the amount of backing material. Determine the amount of UV coating, do not forget, the viscosity of the reasons, if the amount is too large, then, difficult to smooth coating. The UV coating is heated to 40 ℃, can enhance mobility, but also can increase the gloss. Anilox coating also affects the geometry of the flow. Other than carrying capacity, the net number of lines also play a role. Only non-foam coating, can produce good gloss. When the net cavity filled with paint roller, the small bubbles formed in the coating, resulting in the formation of micro-bubble. Defoamer can be added to improve this situation, coupled with a reasonable mix of paint circulation system to ensure that no over-mixing the paint. 5 drying is the point in a few seconds,[link widoczny dla zalogowanych], to give color and luster of the material would be applied to the substrate. While vendors try to make these films to the solid from the liquid quickly. But there are limits to this high-speed printing. Therefore, the coating process must be supported by the drying method chosen. With the production rate increases, the surface sheets to maintain acceptable heat,[link widoczny dla zalogowanych], can not be completely dry and harden. After printing, the direct result of this stack of paper sheets from top to bottom on both sides received response, if the resulting situation can be seen, it is called back rub dirty. The print quality characteristics of UV coating to be stable a few days. Based on the use of inks and coatings, gloss and bonding quality can still be changed after 24 hours. However, the changes are not always drawbacks. Beam hardening coating to protect the surface condition, after drying, it can not change the bottom of it. Stacks of paper sheets in the income pile up one by one, under considerable pressure, therefore, requires the full hardening of the surface sheets to ensure that no one from contact with the back and on the whipped by. The hardened surface is produced by the UV dryer Erzhi appropriate beam energy. To receive stacks of paper drying temperature rise, causing the back rub dirty,[link widoczny dla zalogowanych], sticky paper or page. Therefore, the printing press of the structure, most importantly, when appropriate, impose appropriate drying energy. So, after printing and coating unit, really need to infrared (IR) light, coupled with cold and hot air and exhaust to help. To dry water-based dispersion coating, it is recommended to use between the two polishing units to pass in the form of an extension of the two dried parts. Drying time to decide if that is shiny effect, then, between the two polishing units, plus a delivery component to ensure that the production rate can be increased by 40% without affecting the gloss effect. Drying device output energy must match the production speed. UV output energy must follow the speed of printing, but the non-linear relationship. IR output energy is the linear model. Third, the summary of ultraviolet (UV) coating can be achieved, depending on the substrate. Dispersed with high gloss paint coating on the effect of some substrates, in which substrates for ultraviolet (UVJ polishing can achieve the desired results, can provide a reference. Inks, especially high coverage conditions, resulting in lower gloss, but through the use of high concentrations of pigments and good ink absorption to be improved. ink composition and the affinity of the decision with the backing material coating the bond situation,[link widoczny dla zalogowanych], and after printing a few bonding situation genius really stable. the right to choose the type of backing material and the use of content on the degree of gloss can be achieved a decisive role. UV money (UV) coating as a surface coating helps prevent scratching; the same time, if the coating uniform, may form a bright surface. by choosing the right machine structure, especially given the terms of drying parts,[link widoczny dla zalogowanych], and pay attention to coordination of materials, printing presses to provide a prerequisite to achieve the best results. forbearance
