The color filter manufacturing method for improving precision in correcting color unevenness of a screen surface by eliminating the influence of measurement errors and variance in the ink discharge amount, includes the steps of: coloring a coloring-target medium, using at least two different ink discharge densities, and measuring color densities of colored portions of the coloring-target medium; obtaining a relationship between the color density and ink discharge density based on the respective color densities of the colored portions colored by the at least two different ink discharge densities and corresponding ink discharge densities; and determining an ink discharge density which attains a desired color density based on the obtained relationship between the color density and ink discharge density, and discharging ink onto the color filter substrate at the determined ink discharge density, thereby coloring the color filter substrate.

A color filter manufacturing apparatus can manufacture a color filter with less color unevenness in a short period of time. The color filter manufacturing apparatus forms an array of colored portions of a color filter by discharging a plurality of inks from a plurality of discharge orifices at a predetermined density by using an ink-jet head having a plurality of discharge orifices, an ink chamber connected to the plurality of discharge orifices, an ink supply opening for supplying ink to the ink chamber, and an ink exit opening for exiting ink from the ink chamber. The color filter manufacturing apparatus comprises an ink flow generating device for generating a flow of ink from the ink supply opening to the ink exit opening in the ink chamber while discharging ink from the discharge orifices for coloring. The colored portions are formed when a variation rate of ink volume discharged from the plurality of discharge orifices for forming the array of colored portions is ±3% or less.

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.

A method of instantly measuring the amount of ink discharged from a nozzle of an ink-jet type printhead in a single discharging operation comprises: a density measuring step of measuring the density of an ink dot formed by ink discharged from the printhead onto a glass plate 10, and a determining step of determining the amount of the discharged ink on the basis of the density of the ink dot measured in the measuring step.
摘要:
A method of manufacturing a color filter by dividing a coloring area on a substrate into a plurality of scan areas and applying ink to each scan area from an ink jet head, wherein an amount of ink to be applied to a boundary area between adjacent scan areas is changed from an amount of ink to be applied to an area except the boundary area.

It is an object of this invention to provide a color filter manufacturing method capable of efficiently using an ink-jet head. To achieve this object, there is provided a color filter manufacturing method 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 relatively scanned with respect to a body to be colored on which the pixels, onto which the ink is to be landed, are aligned in advance, including the steps of, when some of the plurality of ink discharging nozzles for discharging the ink onto the pixels are defective, stopping discharging of the ink from the defective nozzles, and compensating for a lack of an ink amount in the Nth pixel owing to an omission of the defective nozzles, by other nozzles for discharging the ink onto the pixels.

The invention has an object to provide a liquid discharge recording method and a liquid discharge recording apparatus capable of outputting images at high speed with high quality and high reliability, and has a feature in that when adjacent overlapping dots are formed on a print material, the dots are formed with a dot placement time difference that may reduce uneven optical densities of the overlapping portion of the dots.
摘要:
A spliced ink-jet head including head chips, each of which is capable of discharging inks of two or more colors, and which are spliced in a staggered manner which restrains the occurrence of splice streaks, white streaks caused by deflection at ends or uneven colors attributable to different landing orders of ink droplets in spliced portions of different colors when one-pass recording is carried out. The head chips is arranged such that, in a relationship between two adjoining head chips, at least one discharge port of one head chip and one discharge port of the other head chip for the same color tone ink in end portions overlap on a line in a recording material feeding direction, while discharge ports for different color tone inks do not overlap.
