PROBLEM TO BE SOLVED: To provide an oily ink set which is suitable for printing polyvinyl chloride substrates, is excellent in print quality, printing stability, and the like, and can give images high in color reproducibility and color degree.SOLUTION: This oily ink set, in which any of the first oily ink, the second oily ink and the third oily ink has a wavelength region changing the reflectance from 80% to 5% on recording media in a wavelength region of 400-700 nm, is characterized in that the reflectance of the second oily ink is continuously higher than that of the first oily ink in a wavelength region where the reflectance of the first oily ink changes from 80% to 5%; the reflectance of the third oily ink is continuously higher than that of the second oily ink in a wavelength region where the reflectance of the second oily ink changes from 80% to 5%; and the color materials of the first oily ink, the second oily ink and the third oily ink all are different. |
