Influence of pitch deposit on the newsprint printability and its control

沉积在新闻纸页中的树脂酸或脂肪酸类树脂在印刷过程中会引起环状白斑、纸页脱层等印刷故障,文章介绍了国外新闻纸厂使用微细滑石粉、硫酸铝及固着剂控制树脂障碍的生产经验。

The pitch deposits from resin acids and fatty acids may lead to the ringlike hickies and paper sheet delaminations in the printing process. The article summarized the production experiences in pitch control by using superfine talc powder, aluminum sulfate and fixing agent in foreign newsprint mills.
