    Abstract: When a malfunction nozzle occur in a joint portion of print elements in a print head, this invention controls the print head to minimize image impairments caused by the malfunction nozzle. This prevents an increase in cost of the print head and increases the printing speed while at the same time realizing a high quality of printed image. For the control of the overlapping nozzles (NA1-NA3, NB1-NB3) in the adjoining print chips (A, B), a desired control mode is selectively set from among a plurality of control modes, the control modes having different nozzles removed from use.,

    Abstract: A color-filter manufacturing method for manufacturing a color filter, with very little color unevenness, in a short period of time. According to the method, at least a single color of red, green and blue ink is discharged onto each pixel of a substrate by using an ink-jet head, and coloring is performed such that color density fluctuation among pixels colored in red is kept 5% or lower, color density fluctuation among pixels colored in green is kept 10% or lower, and color density fluctuation among pixels colored in blue is kept 3% or lower.

    Abstract: It is an object of the present invention to provide a color filter manufacturing method of manufacturing a high-quality color filter with little density irregularity. In order to achieve this object, in a color filter manufacturing method according to the present invention, a color filter is manufactured by coloring the respective pixels with a plurality of discharged inks arranged in the scanning direction while an ink-jet head having a plurality of ink discharging nozzles in a direction substantially perpendicular to the scanning direction is scanned over a substrate. A coloring operation is performed while the ink discharging pattern is changed for each of the arrayed pixels or each pixel group.
