In recent years, the water-based ink have been widely used in various industrial applications due to environmental problems. Dispersibility of the pigment for applications of the water-based ink is the one of the most important technical factors to produce uniform color products. Thus, in this study, the three-roll mill process was used to improve the dispersion of the water-based ink. The results indicated that the three-roll mill reduced the size of pigment particles in the ink more than 50%. In addition, the dispersant showed an important role to maintain the dispersion stability of the pigment in the water-based ink over 120 hours. We also confirmed the optimum contents of the ink stock solution, drying temperature and drying time by the colorimeter and colorfastness tests on produced PET synthetic suedes.
