Objective To study the influence of different addition amount of auxiliary on the dryness of water-based plastic gravure ink. Methods Sample ink of plastic aqueous ink was prepared by means of high-speed grinding dispersal. All the sample ink pigment/binder ratios were the same and only an additive changed its content. The different contents of auxiliary were analyzed by the way of measuring rough dryness of sample ink. Results Suitable dosage increased the drying rate of ink, while unsuitable dosage decreased the drying rate. Conclusion When the contents of pH stabilizer, thickener , dispersant and wetting agent were respective 0.2%, 0.6%, 3.0% and 2.0%, the drying rate of the water-based plastic gravure ink increased, and meanwhile its qualities including viscosity and adhesion were not negatively affected.
