PROBLEM TO BE SOLVED: To provide a construction plate printer capable of performing gradation representation over a wide range of densities from high to low by modifying a diameter or a position of an inkjet nozzle. SOLUTION: A normal density correspondence print head HK1 has a plurality of small-diameter nozzle arrays and a high-density compatible print head HK2 has a nozzle array with holes each having a large diameter arranged in a staggered fashion. The printing in high-density of solid printing is carried out by using the high-density compatible print head HK2 and the printing in the range from medium density to low density is carried out by overprinting by the plurality of nozzle arrays of the normal density compatible print head HK1.
