印出用 油煙墨의 標準粘度에 관한 實驗的 硏究

Abstract

The purpose of this experimental study is to investigate the standard adhesiveness of the traditional Korean ink for printing. The major findings are as follows: (1) Korean traditional ink is a name which people generically calls a block of ink mass made from soots and pine pitch, and it can be classified into pine-pitch ink and oil-pitch ink according to the type of soot. (2) It has been known that pine-pitch ink is appropriate for block printing, while oil-pitch ink is appropriate for printing with movable types. (3) Only oil-pitch ink is currently available, and its basic adhesiveness required for making ink is 18℃ in Japan, 25℃ in China, and 22℃ in Korea. (4) The lower the adhesiveness of an ink stick is, the easier it can be rubbed and the less often it gets cracked. (5) Generally it is better to keep less thinness of traditional Korean mulberry papers, and the standard adhesiveness of ink as 23℃-27℃ , when oil-pitch ink is used for printing with movable types. (6) It is strongly expected that the traditional technique of making oil-pitch ink, currently unavailable, is recovered and succeeded as soon as possible.
