Through experiments the relationship between glossiness and its influence factors were tested. Experiments revealed that the stable dispersion of the water- based ink can help to improve glossiness. Water content of the water based ink deceases the glossiness. The antifoaming agent can decrease the viscosity of the system and influence the dispersion, therefore can harm glossiness. And thickening agent and glossiness have certain curve linear relationship. With mixing of thinner, glossiness of the ink increased. Glossiness is best at pH about 9.0~9.5.
