An experiment has been done to illustrate the optimization of matte lightweight-coated paper quality through coatingrnpigment formulation selection. Low levels of coarse calcium carbonate were used with high shape factor kaolins ofrndifferent sizes. Overall quality functions were defined as combinations of optical, physical and printabilityrnproperties. Results show that significant variation in major sheet properties and in overall quality can be obtainedrnthrough changes in the coating pigment formulation. It is shown that quality can be accurately predicted from thernamount of coarse calcium carbonate used and the particle size of the kaolin.
