摘要： Provided is a can manufacturing method, comprising: creating separation data by separating platemaking editing data for each ink color of a printing machine that performs printing on a surface of a can; and manufacturing a proof can by outputting an image corresponding to the platemaking editing data by an ink-jet printer based on the platemaking editing data or the separation data and a predetermined conversion rule, and arranging the image on a can surface, wherein the conversion rule has a rule to reproduce, by ink of the ink-jet printer, the ink color of the printing machine printed based on the separation data.

摘要： A plate-making method for manufacturing a printing plate includes: manufacturing the printing plate based on a knockout method in which knockouts of halftone dots in one color are formed, and halftone dots in the other color are overprinted onto positions of the knockouts; for each of pixels, when a sum of a halftone dot area ratio of the one color and a halftone dot area ratio of the other color is smaller than 100%, forming a gap from a knockout in the one color around a halftone dot in the other color; and for each of pixels, when the sum of the halftone dot area ratio of the one color and the halftone dot area ratio of the other color is greater than 100%, forming an overmask such that the halftone dot in the other color penetrates a periphery of the halftone dot in the one color.
