A clear ink composition for UV-LED curable inkjet printing, including 44-80 mass% of a photopolymerizable monofunctional monomer, 15-50 mass% of a photopolymerizable polyfunctional monomer, and 5-15 mass% of an acylphosphine-based photopolymerization initiator, the viscosity of the clear ink composition at 25 DEG C being 1-50 mPa.s, the photopolymerizable monofunctional monomer and the photopolymerizable polyfunctional monomer including a photopolymerizable monomer having at least one functional group selected from an amide group and an amino group, and the photopolymerizable monomer being contained in a ratio of 5-20 mass% of the combined total amount of the photopolymerizable monofunctional monomer and the photopolymerizable polyfunctional monomer.
