Applications alcohol - water system Notes 1. appropriately reduced ink plate depth due to the alcohol - low water system solvent ink ratio (water-based gravure inks versa), ink binders, pigments and other active ingredients the ratio will be relatively high, so that, Huang Jiang label printing, color saturation of printed products have a certain degree of protection. However, to reduce the proportion of fast-drying solvent ink drying will have some impact, therefore, under the premise of protecting the printed color saturation, the proposed solvent ink printing on the basis of network points to reduce the depth of the plate. Previously, the printing ink cell depth company solvent inks reach 52μm, the application of alcohol - water system after the ink, printing ink cell depth is reduced to 30 ~ 35μm. Although individual printing network point anti-Indian forces decreased, but due to lower solvent ink total consumption, overall costs still have some savings, and dried to obtain a printed product also improved. In addition, the workshop using an alcohol - water system at the smell of ink unit has been reduced to a large extent. 2. The printing ink viscosity of alcohol - water system using a light ink after printing, especially when printing large format products, label printing, we must strengthen the monitoring of the ink viscosity. This is because the printing process, the ink viscosity when significant changes occur, Zhangmutou label printing, will lead to greater volatility of printing ink. In addition, the printing process also concerned about the impact of other factors on the viscosity of the ink, such as pH value. Alcohol - water ink pH was maintained at 9 to 9.5, you can ensure a good flow of ink, ink binders can avoid precipitation of the relatively low amount of ink in the consumption of color groups, in particular, to strengthen the ink pH value measurement, and replenish the special ink pH value adjustment agent. In addition, after a long non-stop printing, but also regular filter color group, especially for some small amount of ink ink color groups, to precipitate the excess ink binders, pigments and ink impurities filtered, and ultimately ensure stable printing quality. Problems ink temperature technology has been developed over the years. Waterless offset is still very complex process, each step requires perfect control, it can be up to a very high print quality. When the printing speed is more than 150 meters per minute, wet offset printing requires cooling rolls, cooling in the printing unit accumulated heat may affect the performance of the ink and ink density. Waterless offset printing speed is required in any chill roll and cooling Mexican road, and in the master roll center cooling plates. Because the temperature of the ink on the print quality control is extremely sensitive. Ink operating temperature is limited to a very narrow range, only 3-4 ℃, above or below this temperature, the ink becomes unstable and print quality may be affected. To achieve better control the printing effect, the factory needs air conditioning thermostat. Offset printing is the most demanding mechanical components printing process. Just when there's a limit flexo printing pressure, offset it takes a lot of pressure imposed on the master roll in order to transfer the ink. Working poor, assembly, and firmness, Hengli label printing, as well as ink path design and ink management system, will affect the offset printing unit to the final print quality. Most of the market offset head can be up to an acceptable print quality at 30-40 meters per minute machine speed. To more than 50 meters per minute machine speed, to get sustained good quality prints. XpanndTM offset printing head 12 meters per minute print speed will be able to get consistently high quality printing. In setting the amount of waste from India in small, very close to the flexo process. Qishi label printing, beyond printing (online consultation), label printing by the Dongguan City, often beyond packaging products factory provided. Dongguan Chang-ping beyond packaging products plant (www.dgcyp.com) Dongguan, Guangdong, printing paper leaders, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In all walks of life beyond the printing leadership with the staff warmly welcomed the inquiry negotiations to create a better future beyond printing.
