PROBLEM TO BE SOLVED: To provide an aqueous inkjet ink set that has excellent printability on a general print medium, particularly a print medium having low water absorption such as coated paper, art paper and polyvinyl chloride sheet and can give a high-quality image.SOLUTION: The aqueous inkjet ink set includes a deep color ink and a light color ink having at least the same hue but different color densities. Each ink comprises at least a colorant, an organic solvent (A) having a boiling point of 200°C or higher and 280°C or lower and a surface tension of 20 mN/m or more and 30 mN/m or less, and water. The light color ink further contains a water-soluble organic solvent (B) having a boiling point of 50°C or higher and 180°C or lower. A difference in the viscosity at 25°C between the deep color ink and the light color ink is 3.5 mPa s or less.SELECTED DRAWING: None |
