Abstract:
A water-based printing ink composition for gravure printing and a method for producing the same are provided. The water-based printing ink composition includes: 1 to 15 parts by weight of a pigment, 1 to 50 parts by weight of an aqueous resin mixture, 1 to 20 parts by weight of a quick-drying agent, and 30 to 80 parts by weight of water. The aqueous resin mixture includes a first aqueous resin and a second aqueous resin, a first glass transition temperature of the first aqueous resin is greater than a second glass transition temperature of the second aqueous resin, and an absolute value of the difference between the first glass transition temperature and the second glass transition temperature is not less than 40° C. The quick-drying agent is an alcohol or a ketone, and the quick-drying agent has a boiling point of not greater than 85° C.
