Provided is an ink including water, organic solvents, a color material, and resin particles, wherein the ink is used in a printing method including applying the ink onto a substrate including a resin to print, and the organic solvents include a compound, a diol compound including 3 or 4 carbon atoms, and 2-ethylhexyl alcohol, where the compound has a boiling point of 170°C or higher and an absolute value of a difference between Fh of the compound represented by Mathematical Formula 1 and Fh of the resin in the substrate represented by Mathematical Formula 1 is 5% or less, Fh % = δH / δD+δP+δH × 100 where, in Mathematical Formula 1, δH is a hydrogen bond term of the Hansen solubility parameter, δD is a dispersion term of the Hansen solubility parameter, and δP is a polarity term of the Hansen solubility parameter. |
