CHARACTERIZING THE EFFECT OF CALENDER ON INK PENETRATION AND DISTRIBUTION USING LSCM
The structure of the coating layer has a strong influence on the optical and physical properties of paper as well as on the print quality. Ink is transferred and sets onto the paper surface in the printing process, which affect printing quality and usage of ink. The objective of this study was to investigate the influence of calendering on ink absorption and characterize the penetration depth through quantitative analysis by Laser Scanning Confocal Microscope (LSCM). Calendering was carried out to change the coating structure and properties. Fluorescent ink was used to observe and characterize the ink penetration by LSCM. Three-dimensional images of ink pigment penetration were obtained by reconstructing all XY plane images. This method could not damage the specimen and did not need fluorescent dye to stain the specimen, which reduced errors by hand operation. It could be concluded that Calendering can improve the smoothness, gloss and paper surface efficiency of coated paper, which resulted in lower amount of ink usage, more even ink absorption and higher print density.
