We dyed traditional Korean hand-made papers (Hanji) with colorants extracted from fruits of Alnus japonica to investigate the effect of various dyeing factors (mordant, dye concentration and dyeing assistant) on colors, K/S values and light fastness of the dyed Hanji. The dyed hanji had brown color. The K/S value of dyed Hanji was increased by mordanting with alum and copper acetate. $a^*$ and $b^*$ value of dyed Hanji was decreased slightly by mordanting with alum and Iron(II) chloride. The K/S value and $b^*$ of dyed Hanji increased with increasing concentration of dye, but $L^*$ value of dyed Hanji decreased. The K/S value of dyed Hanji was also increased by fixing agent. When Hanji was mordanted with Iron(II) chloride and was not mordanted, use of fixing agent resulted in greater increase of K/S value. Use of fixing agent resulted in poor light fastness. When fixing agent was used, mordanting with copper acetate resulted in smaller color difference than mordanting with alum after aging test.
