EFFECT OF BASESTOCK FORMATION ON PAPER COATING

Basestock formation influences coated paper quality through coating we ight distribution. This study investigates the effect of basestock for mation on the optical and physical properties of coated paper. Better formation produced more uniform pore structure for the basestock and t he coating layer. The mean pore size decreased with increasing formati on index. Improving formation reduced the bulk and roughness of the ba se-stock and increased the basestock gloss and the light-scattering co efficient of the coated paper. No significant correlation existed betw een the formation index and the roughness and gloss of the coated pape r.
