Abstract
An inkjet printing system includes an inkjet head including first to n-th nozzles disposed in a row in a first direction, where the inkjet head discharges an ink onto a pixel printing target substrate, a transfer part which transfers the pixel printing target substrate toward the inkjet head in a second direction perpendicular to the first direction, a discharge waveform signal generator which generates different discharge waveform signals based on a pixel interval in the pixel printing target substrate and a transferring speed of the pixel printing target substrate, and a discharge waveform signal selector which selects first to n-th discharge waveform signals among the plurality of different discharge waveform signals based on discharge position error data respectively corresponding to the first to n-th nozzles, such that the first to n-th discharge waveform signals are selectively provided to each of the first to n-th nozzles.
