PROBLEM TO BE SOLVED: To reduce protrusion of discharged droplet out of a pixel region in an ink jet printing method for forming pixels on a display panel.SOLUTION: In an ink jet printing method for discharging ink droplets from an ink jet head 3 having plural nozzles 3a to a board 1 used for a display panel comprising plural separated pixel regions to supply the ink to the pixel regions of the board, plural nozzle groups are allocated and arranged in each pixel region so that the number of discharged droplets is equal to an indicated number of droplets, the droplets discharged from the plural nozzles are beforehand impacted to a reference impact grid as an impact-scheduled impact position on the board surface, a predicted impact position is calculated as a predicted impact grid on the basis of a displacement amount from the reference impact grid, the predicted impact grid contained in each pixel region out of predicted impact grids is selected as an in-pixel predicted impact grid, and the indicated number of droplets is distributed to the in-pixel predicted impact grid every pixel region, and the ink is discharged. |
