Ink Additives Improve Print Quality

Powder-free paper printing ink additives have been successfully developed by Hangzhou West Lake Printing Industrial Company. This technology will greatly improve the quality of lithographic packaging printing processes.

In high-end high-speed color lithographic packaging printing, because the back of the product is easy to stick, a large number of defective products and waste products are often produced. Domestic and foreign generally increase the dusting process to solve, but dust pollution on the environment, but also unfavorable mechanical transmission and lubrication components, but also affect the print gloss. In order to solve this problem, Hangzhou Westlake Printing Industry Co., Ltd. took the “ink-free printing paper printing ink additive” as the subject of research, and received the support and guidance of experts from the National University of Science and Technology of China National Chemical Laboratory, successfully developed the powder-free ink additive, and Good results in practical applications.

According to experts, this technology uses powder-free additives prepared from ethylene-modified resins, ethylene-vinyl acetate copolymers, and aluminum stearate to replace the new powder spraying process in lithographic packaging and printing, significantly increasing the yield of printed products. , Simplify the production process, innovation in resin selection, formula design and printing process, etc., and it is at the leading level in China.
