Document Type and Number:
WIPO Patent Application WO/2022/131442
Kind Code:
A1
Abstract:
The present invention relates to an inkjet printing method for coating a thin film, capable of overcoming variations in ink ejection characteristics of each nozzle and minimizing variations in thickness of a coating thin film. To this end, the inkjet printing method for coating a thin film of the present invention comprises: a dot pattern printing process of printing a dot pattern hit group by discharging ink to a predetermined target surface position by using a nozzle group for forming a dot pattern so as not to have hit droplets overlap each other; a connection pattern printing process of printing a connection pattern hit group by discharging ink to a position between a plurality of neighboring patterns by using a nozzle group for forming a connection pattern so that the same attractive force acts on a plurality of neighboring patterns that are hit on the target surface; and a finishing printing process for finishing the coating of the target surface by discharging the ink to an area other than the plurality of neighboring hit droplets by using a finishing nozzle group so that the same attractive force acts on the plurality of hit droplets that are hit on the target surface.
