Karakami is paper which was imported from the Tang dynasty in China in 8th century (in the Heian period) and gradually it came to be made in Japan.
For classic works of calligraphy (Kohitsu). Karakami is used for “Sunshōan-shikishi and Kansuhon Kokinshū.
(Shikishi is a square piece of high-quality paperboard for writing poems or painting pictures)
(Kansuhon Kokinshū is a scroll of imperial poetry anthology)
Printed paper (Karakami) is made as follows:
First, to make the groundwork of paper, whitewash dissolved by glue is varnished onto paper which is covered with dosa to prevent ooze. Dōsa is made by mixing glue and alum and then diluting with water.
Secondly, mica powder dissolved by glue and gloiopeltis glue (funori) is evenly scattered all over on a woodblock by a dabbler.
Then paper daubed with whitewash is put on it and rubbed with a baren.
(baren is a tool for printing a woodblock).
