An object of the present invention is to provide a precoat liquid which can prevent the penetration of an actinic radiation-curable ink into a recording medium and which is less likely to damage the texture of the recording medium. A precoat liquid, capable of achieving the object, for an actinic radiation-curable ink includes a hydrophilic polymer, a hydrophilic solvent, water, and resin fine particles. The amount of the hydrophilic polymer is 1 part by mass or more and 100 parts by mass or less with respect to 100 parts by mass of the hydrophilic solvent.
