1. An inkjet printing method for a thin-film coating, the method comprising:
a dot pattern printing process of printing a dot pattern by discharging ink at a preset position on a surface of an object using a nozzle group for forming a dot pattern so that dropped droplets are not in overlap with each other;
a connection pattern printing process of printing a connection pattern group by discharging ink at a position between a plurality of neighboring patterns using a nozzle group for forming a connection pattern so that the same attractive force acts to the plurality of neighboring patterns dropped on the surface of the object; and
a finishing printing process of finishing a coating on the surface of the object by discharging ink to an area except for a plurality of neighboring dropped droplets using a nozzle group for finishing so that the same attractive force act to the plurality of dropped droplets that are dropped on the surface of the object.
