In order to obtain water-based digital printing ink with good coloring property, different kinds of pigments were used to prepare ink samples, by testing the tinting strength of samples to discuss the influence of the variety of pigments and the characteristic of pigments on the coloring property of ink. By changing the content of pigment, as well as the dispersity of pigment, to prepare ink samples, investigate the effect of the content of pigment and the dispersity of pigment on the coloring property of ink. The results showed that different characteristic of pigment has key influence on the tinting strength of ink. The content of pigment is also an important factor that affects the tinting strength of ink. When the content of pigment increases to a certain value, the tinting strength of ink will reach the best state. Besides, the tinting strength will become better with the improvement of dispersity of pigment.
