초록

The emulsification of lithographic printing inks are very important to determine printing quality. In this study, we measured the variation of water pickup according to the hardness of water in dampening solution. In order to observe the rheorogical properties of the emulsified inks, we measured the viscosity, the elastic return, the thixotropy area and yield stress value of the emulsified inks. In this paper, we found that the water pickup of the ink increase the hardness of water with the amount of dampening solution. Also, The viscosity, the yield stress value and the thixotropy area were increase by the water pickup of the ink.
