1. An inkjet printing device, which is for multi-color printing, comprising:
multi-color inkjet nozzles that move in a direction perpendicular to a moving direction of a target base printing material and also in a direction parallel to a surface of the target base printing material, while printing on the target base printing material;
plasma ejection ports provided downstream of the multi-color inkjet nozzles in the moving direction of the target base printing material in a manner oriented facing a surface of multiple colored inks printed on the target base printing material, wherein an opening part of each plasma ejection port is oriented in a manner that a plasma ejected from the opening part of the plasma ejection port is set to be oriented toward a direction opposite the moving direction of the target base printing material; and
an electron beam irradiation part located on a downstream side of the multi-color inkjet nozzles and plasma ejection ports in the moving direction of the target base printing material, in a manner oriented facing the printed surface of the target base printing material.
