Effect of Calendering Conditions on the Optical Properties and Printability of Art Paper
Calendering temperature,speed and linear load were chosen as calendering parameters to do the orthogonal experiment.By changing the value of the three parameters,the influences of calendering condition on opacity,brightness,smoothness,paper thickness,gloss and ink absorption were studied.The art paper coating formulations are as follows: GCC-60 100 pph,solid content 64.6％ for precoating; GCC-95 40pph,Kaolin 60 pph,and solid content 61.3％ for top coating.Bar coater was involved to coat by hand in the lab and the coating weight was controlled at 20±2g/m2.After calendering in different conditions,the optical properties and printability of paper were measured and then the trends of these paper properties were analyzed.Regression analysis was used to study which of the calendering conditions was the dominant factor influencing the paper properties.The results showed that linear load was the dominant one,followed by the calendering temperature and calendering speed.After calendering,smoothness and gloss increased,while the brightness and opacity decreased.
