Zusammenfassung:	There is provided a plate-making method for manufacturing printing plates capable of representing colors by overprinting halftone dots in at least three colors of a plurality of process colors. The plate-making method includes: overprinting two colors of the at least three colors by a knockout method in which knockouts of halftone dots in one color of the two colors are formed, and halftone dots in the other color are overprinted onto positions of the knockouts; and overprinting a remaining color of the at least three colors onto the two colors by an overprint method in which at least part of halftone dots in the remaining color is put on the halftone dots in the one color and/or the halftone dots in the other color. The remaining color includes at least white.
