Abstract: In this paper the process of digital printing using the reactive dye ink on grain leather was studied. In order to solve the problem of poor rubbing fastness, different reagents were used on leather respectively before printing. When the leather was overprinted with the modifier G after digital printing and being baked for 3 minutes at 140 ℃, the printing was chic and bright in color. The dry rubbing fastness of the printed leather was improved by 2 grades and the wet rubbing fastness increased by 1 ~ 2 grades. After the printed leather was finished with water-base resin, the dry and the wet rubbing fastness were both improved to 4 ~ 5grade.
