Abstract

Disclosed is an ejection volume compensation method of an inkjet printer for manufacturing an organic electroluminescent device pixel. The inkjet printer includes a plurality of nozzles and is configured to perform a plurality of print processes for the same pixel location. A target ejection volume for the next print process is selected so that an average of the target ejection volume and an actual ejection volume for the previous print process is equal to an ideal ejection volume. Also disclosed are an ejection volume compensation device for use with the inkjet printer, an inkjet printing device, and a non-transitory machine readable medium.
