PROBLEM TO BE SOLVED: To provide a printer which suppresses nozzle clogging of an ink ejection head.SOLUTION: A printer comprises: a carrying device which carries a medium; a first head 31 which ejects radiation curable first ink onto the medium; a second head 32 which is arranged on a downstream side in a carrying direction of the first head and ejects radiation curable second ink onto the medium; a first irradiation part 41 which is arranged between the first head and the second head in a carrying direction and irradiates the first ink ejected from the first head with radiation having intensity at which the first ink does not completely cure; and a second irradiation part 42 which is arranged on a downstream side of the second head in a carrying direction and irradiates the second ink ejected from the second head with radiation having intensity at which the second ink does not completely cure. A distance between the first head and the first irradiation part is shorter than a distance between the first irradiation part and the second head and a distance between the second head and the second irradiation part, and content of polyfunctional monomer having 3 functions or more in the first ink is smaller than that in the second ink. |
