Abstract:
Provided is a gravure printing method by which high printing density and excellent highlight suitability are obtained, even if a gravure plate having high resolution and reduced thickness is used. The gravure printing method comprises: using an aqueous ink having a Zahn cup #3 viscosity at 20° C. of 11.0 seconds or more and 20.0 seconds or less, and having an evaporation rate of 30 mass % or less in a drying test, the drying test involving drying 1 g of the ink at a temperature of 40° C. and an air flow of 1,400 L/min for 30 minutes; and transferring 1 ml/m2 or more and 7 ml/m2 or less of the ink onto a printing medium.
