Application of Calendering Process to Roll-to-Roll Printed Electronics

This paper presents the design of calendering machine and experimental results of calendering process. A particular pattern was printed on PET film by means of roll-to-roll gravure printing machine. The calendering process was applied to a set of samples and the effect was analyzed after measuring the surface roughness and the thickness of pattern. Although only mechanical pressure provided by a nip roll was applied during the calendering process, the experimental results indicate that the calendering process should be useful for enhancing the surface quality of roll-to-roll printed electronics products.
