Investigation into the Effect of Binder on Print Quality of Coated Paper
In the offset printing process, it often occurs that the coating layer can not absorb ink equably andink on the coated paper can not dry at even speed. When coated paper moves through the next printing unit,the quantity of ink peeled off from image is not same. When the difference of ink peeled off by the blanketcylinder can be observed, the color of printing is not uniform and print mottle occurs. The physical structureand chemical properties of coating layer affect transferring and setting of the ink. Binder which is the importantcomposition for coating layer is detrimental to surface topography and chemical properties of coated paper.In this study, the effect of binder on print quality of coated paper was investigated. Binder migration hadtwo trends which were towards coating surface and interior of base paper. Binder can not distribute evenly onthe coating surface in the process of coating solidifying and drying, which affect surface topography of coatinglayer and ink absorption. The main objective of this study was to investigate the effect of binder of coatedpaper on surface properties of coating layer and print quality. The binder migration of coating layer was obtainedby changing drying temperature. The relationship between binder and print quality was explored by inkabsorption uniformity.
