초록

Talc has been used as coating pigments for gravure printing paper and light weight coated paper (LWC) in Europe for 30 years and the use of talc has been significantly increased every year. Currently, talc is used for about 15% of pigments for paper coating. Especially more than 50% of the coating pigments for gravure printing paper and web printing paper (web off-set) is applying talc. The use of talc improves printability, smoothness, and the coverage of base paper, and showed a significant effect on reducing the coated paper basis weight. In addition, it improves compressibility of the coating layer, influencing the gravure printability.
