The morphological properties of the traditional handmade papers made in Korea, China and Japan were identified using CLSM(Confocal Laser Scanning Microscope). It was shown that the primary and secondary wall of the Hanji fibers were separated. The lumen of the fibers was not observed. Dochim, a traditional way of Hanji calendering, was turned out to accelerate the separation of the two walls, by which the unique effects of Dochim could be obtained. There were no separation of the two walls in Chinese handmade paper and Japanese handmade paper. Lumen was not observed in Senji fibers but it was observed in Whasi fibers. It was postulated that the morphological properties of the fibers are closely related with the calligraphic writings or drawings properties of handmade papers.
