Study on Coating Surface Topography and Properties of Coated Paper Related to Pigment

Article Preview

Abstract:

The physical structure and chemical properties of coating layer have an important influence on transferring and setting of the printing ink. In this study, the effect of pigment on coating layer structure and surface properties was investigated. The surface topography was explored using scanning electron microscopy (SEM) and atomic force microscopy (AFM). The findings indicated that the pigment affected the pore size, depth and distribution of the coated paper surface. The conclusions were drawn that coating could improve coating surface topography and calcium carbonate pigment compared with kaolin pigment was not good to the paper surface properties, which resulted in high roughness, low paper gloss, high ink absorption and low paper surface efficiency.
