PROBLEM TO BE SOLVED: To provide a printing apparatus capable of printing uniformly even to the inside of a material to be printed by an inkjet method.SOLUTION: In an ink supply device 3, a plurality of nozzle rows 16a and 16b having a plurality of nozzles 15a and 15b arranged in the direction intersecting with respect to a moving direction of a material P to be printed respectively are disposed with each other at an interval d with respect to the moving direction of the material P to be printed. By dropping ink by an ink jet method from each of the nozzles 15a and 15b of the plurality of nozzle rows 16a and 16b with respect to the material P to be printed to which a coagulant A is supplied by a coagulant supply device 2, ink is supplied in a plurality of separate times in the same region of the material P to be printed. A control part 5 controls the ink supply device 3 and a mobile device 1 so that a printing time difference becomes equal to or more than ink permeation time. |
