Abstract
A method for inkjet printing includes providing a light blocking member pattern including a plurality of openings at positions corresponding to pixels, dripping a dummy ink drop on the light blocking member pattern by using an inkjet printer, providing a CCD (charge-coupled device) image for the dripped dummy ink drop, representing the CCD image on rectangular coordinates, calculating a central point under an x-axis and a y-axis of the CCD image, calculating an escape value as a deviation of the central point under the x-axis and the y-axis in the CCD image from a reference point established by the inkjet printer, calculating a time adjustment value of the ink drip based on the escape value, and controlling the time for the ink drip for each nozzle of the inkjet printer by the time adjustment value of the ink drip.
