Abstract:
A process for producing a color filter by dividing a coloring region on a substrate into a plurality of scanning regions and successively coloring the respective scanning regions by an ink-jet system, comprising the steps of:performing a first coloring operation for a first scanning region in the plurality of scanning regions by repeating a main scanning operation of moving an ink-jet head relative to the substrate a plurality of times in a predetermined direction and a subscanning operation of moving the ink-jet head relative to the substrate a plurality of times in a direction perpendicular to the predetermined direction by a relatively small first distance; performing a subscanning operation of moving the ink-jet head relative to the substrate once in the direction perpendicular to the predetermined direction by a relatively large second distance; performing a second coloring operation for a second scanning region in the plurality of scanning regions by repeating a main scanning operation of moving the ink-jet head relative to the substrate a plurality of times in the predetermined direction and a subscanning operation of moving the ink-jet head relative to the substrate a plurality of times in the direction perpendicular to the predetermined direction by the first distance, wherein the second distance in the subscanning operation step is such that the first scanning region and the second scanning region overlap each other, and the overlapped region is colored by the first coloring operation in the first coloring operation step and the second coloring operation in the second coloring operation step.
