Beschreibung
Zusammenfassung:	The present invention relates to an aqueous gravure ink containing a pigment, a water-soluble organic solvent, a surfactant and water, in which the water-soluble organic solvent contains a glycol ether having a boiling point of 100 to 260° C.; the surfactant contains a silicone-based surfactant containing a specific constitutional unit; a content of the water-soluble organic solvent in the ink is 1 to 10% by mass; and a content of water in the ink is 50 to 80% by mass. This ink exhibits a less burden on the environments, and is excellent in optical density and drying properties.
