Modified Starch Develoved for the High Solid and High-Speed Coating

Abstract

Recent development of printing technology requires high quality printing paper. Modern paper mills have high-speed coaters which usually operate around 1, 500 m/min for productivity inprovement. We have developed a modified starch suitable for high-speed coating. It can be prepared with higher solid coating color formulation than usual starch. Coated paper quality, including such as paper gloss etc., is improved. Also offset printabilities, including such as ink receptivity and trapping mottle etc., are improved. Since we have marketed this product, I would like to explain details of our product development effort and its applications.
