temperature-gradient (tg) calendering produces smooth, glossy surfaces with less bulk reduction than conventional machine calendering. the unheated paper web is calendered in a single pass through a nip between two hot calender rolls. the web touches the hot rolls only in the nip. consequently, the surface fibers are permanently deformed to a greater extent than the fibers in the middle of the paper, and a better surface finish can be achieved with less bulk reduction. in this study, sized and unsized food boards were calendered using both the tg and the conventional calendering methods. the objective of the study was to determine whether there are any benefits in applying the tg-calendering technique to food boards and other heavy paper products. 8 refs
