Powder-free paper printing ink additive was successfully developed

Recently, the powder-free paper printing ink additive was successfully developed by Hangzhou West Lake Printing Industrial Company.

In the high-end high-speed color lithographic packaging printing, the most common, most prominent and most difficult problem to solve is that the back of the product is dirty and it will cause a large number of defective products and waste products. Domestic and foreign generally increase the dusting process to solve the problem of sticky and dirty prints. However, dust not only pollutes the environment, but also is harmful to mechanical transmission and lubrication. It is difficult to clean the equipment and affects the glossiness of printed materials.

In order to solve this double problem, Hangzhou Westlake Printing Industry Co., Ltd. after a lot of investigation and study formulated a practical technology research topic of "ink-free paper printing ink additives," set up the research group, and received support from experts such as China University of Science and Technology National Chemical Laboratory. And guidance. After numerous formulation adjustments, experiments, analysis and improvements, the successful development of powder-free ink additives has been successfully achieved in practical applications.

This technology uses powder-free additives made of ethylene modified resin, ethylene-vinyl acetate copolymer, aluminum stearate and other components to replace the new powder spraying technology in lithographic packaging printing, greatly improving the printing yield and simplifying production. Technology; The technology has been innovative in resin selection, formulation design and printing process, and is at the leading domestic level.

This technology has universal guiding significance and obvious social and economic benefits for improving the printing process of lithographic packaging.
