Coating Pigment Formulation Selection to Optimize the Quality of Matte Lightweight-Coated Paper, 2003 Spring Technical Conference Proceedings
An experiment has been done to illustrate the optimization of matte lightweight-coated paper quality through coating pigment formulation selection. Low levels of coarse calcium carbonate were used with high shape factor kaolins of
different sizes. Overall quality functions were defined as combinations of optical, physical and printability properties. Results show that significant variation in major sheet properties and in overall quality can be obtained
through changes in the coating pigment formulation. It is shown that quality can be accurately predicted from the amount of coarse calcium carbonate used and the particle size of the kaolin.
