Abstract:
A color filter manufacturing method comprising the steps of:discharging an ink from a plurality of ink discharging nozzles onto a plurality of pixels and forming colored portions while an ink-jet head having the plurality of ink discharging nozzles is scanned relatively to a body to be colored on which the pixels, onto which the ink is to be landed, are aligned in advance, wherein each one pixel of the plurality of the pixels is colored by a plurality of ink droplets discharged from two or more assigned nozzles of the plurality of ink discharging nozzles; determining whether any of the plurality of ink discharging nozzles for discharging the ink onto the pixels are defective; stopping discharging of the ink from nozzles determined to be defective in said determining step; and compensating for a lack of a sufficient ink amount in a pixel to be colored by the defective nozzles of the plurality of pixels, due to the stopping of discharging from the defective nozzles, by discharging the ink onto the pixel to be colored by the defective nozzles from nozzles other than the defective nozzles, wherein when a defective nozzle is among the two or more assigned nozzles for a particular pixel, the lack of sufficient ink amount is compensated by discharging the ink from one or more other nozzles of the assigned nozzles for the particular pixel.
