Abstract: [Object] To provide a recording method by which the occurrence of bleeding and repelling in a cured layer can be suppressed during overprinting.[Solution] In a recording method, a first ink composition containing a colorant, a photopolymerizable compound, and a photopolymerization initiator is ejected from a recording head onto a recording medium; light is emitted from a light source to the first ink composition that has adhered to the recording medium with the result that the first ink composition is cured at a cure rate that is in the range from 70 to 95%; a second ink composition containing a colorant, a photopolymerizable compound, and a photopolymerization initiator is ejected from a recording head to the first ink composition that has been cured on the recording medium; and light is emitted from a light source to the second ink composition.
