PROBLEM TO BE SOLVED: To provide a manufacturing method for a color filter which forms swells of inks of three colors for constituting a color filter on one intaglio plate roll and printing the three colors on a transparent substrate, etc., directly or through a blanket roll. SOLUTION: A swell of transparent coloring ink of one color is formed on each recessed part 1a of a tri-color simultaneous printing plate roll 1 which has recessed parts 1a arranged corresponding to patterns of the three colors of pixels of the transparent coloring ink of the color filter and also has non- pixel parts (parts corresponding to a black matrix) where no ink is held as ink-repellent surfaces to form swells of the transparent inks of the three colors R, G, and B at all the recessed parts 1a, 11, etc.; and the swells are transferred to the blanket roll 2 and further printed on the transparent substrate 4 for the three colors at the same time. |
