Abstract: An inkjet printing method includes generating an initial sequence in which initial numbers are arranged in a matrix form, generating a correction sequence by correcting the initial numbers with correction numbers based on a variable range for a volume of droplets ejected into pixel areas and measurement error range for discharge volume of nozzles which discharge droplets to the pixel areas, and discharging droplets to the pixel areas while adjusting a discharge volume for each nozzle based on the correction sequence.

Abstract: An inkjet printing method includes forming a sequence of sequence numbers corresponding to a pixel matrix including pixels arranged in X rows and Y columns (where X and Y are respective natural numbers), setting nozzle combinations for the pixels, respectively, according to the sequence, and discharging ink to the pixels using respective combinations of nozzles respectively corresponding to the nozzle combinations for the pixels.
