Abstract

This study was performed to improve the printability of Hanji using a microbial cellulose from Saprolegnia ferax through investigating the printability of Hanji sized with the mixture of the microbial cellulose and various kinds of sizing agents. Conclusions obtained from the results of this study were as follows. The proper concentration of a microbial cellulose in sizing a printable Hanji with it was 0.5%. In general, there was no remarkable effect but some effect on the opacity and ink density. Hanji was sized with the mixture(5:5) of microbial cellulose(0.5%) and AKD(1.0%). As a result, ink spread was remarkably improved by the girth reduction of ink spot. There was remarkable effect because the mixture(5:5) of a microbial cellulose(0.5%) and CMC(1.0%) improved not only the gloss but also the density and girth of ink spot. Mixing(7:3) with corn starch(3.0%) showed the smallest girth of ink spot among applied sizing agents. Mixing(7:3) with PVA(5.0%) also showed some effect in the density and girth of ink spot.
