Research on the Coating Surface Microstructure of Coated Paper Related to Binder Migration

Abstract:

The surface topography and properties of coating layer have an important influence on penetration and distribution of the print ink. In this research, the main objective was to investigate the effect of binder migration on the coating surface microstructure. The surface microstructure was explored in the method of numerical and visual analysis using mercury porosimetry measurement, scanning electron microscopy (SEM) and atomic force microscopy (AFM). The findings indicated that the binder migration on the coating surface affected the pore size, depth and distribution of the coated paper surface. The little binder migration in the consolidation phase of coating color made a contribution to the forming of the coating layer, which made the coating surface more smother to printing performance.
