1. A method for producing a recorded matter comprising:
a first ejection step of ejecting a first ink, which is a radiation-curable ink jet composition, and adhering the first ink to a recording medium;
a first irradiation step of irradiating radiation to the first ink adhered to the recording medium to obtain a cured coating film of the first ink;
a second ejection step of ejecting a second ink, which is a radiation-curable ink jet composition, and adhering the second ink with a plurality of dot sizes to the cured coating film of the first ink so that the duty is less than 100%;
a second irradiation step of irradiating radiation to the second ink adhered to the recording medium to cure the second ink, obtaining a recorded matter; and
a lamination step of laminating, in the recorded matter, a recording surface of the recording medium to which the first ink and the second ink are adhered, and a non-recording surface of the recording medium to which the first ink and the second ink are not adhered, so that both surfaces face each other,
wherein the non-recording surface of the recording medium is at a back side of the recording medium that is opposite to the recording surface of the recording medium.
