A printing system comprising: characteristic-parameter-acquisition-chart output means for outputting a characteristic parameter acquisition chart (100;200) including a pattern for acquiring characteristic parameters related to characteristics of a printing system; image reading means for reading the characteristic parameter acquisition chart (100;200) output by the characteristic-parameter-acquisition-chart output means ; characteristic parameter acquisition means for acquiring the characteristic parameters by analyzing a read image of the characteristic parameter acquisition chart (100;200) acquired by the image reading means; halftone process generation means for generating halftone processing rules that define halftone processes used in the printing system based on the characteristic parameters acquired by the characteristic parameter acquisition means ; setting means for setting a parameter that is related to a system error assumed in a case where printing is performed by the printing system and includes the characteristic parameters; means for generating a simulation image in which the system error indicated by the parameter is reflected; and image quality evaluation means for evaluating image quality of the simulation image in which the system error is reflected, wherein the system error includes a characteristic error expected to exhibit reproducibility as the characteristics of the printing system, and a random system error as an irregularly changed error, and the halftone process generation means generates the halftone processing rule based on a simulation image in which evaluation falls in a target range. characteristic-parameter-acquisition-chart output means for outputting a characteristic parameter acquisition chart (100;200) including a pattern for acquiring characteristic parameters related to characteristics of a printing system; image reading means for reading the characteristic parameter acquisition chart (100;200) output by the characteristic-parameter-acquisition-chart output means ; characteristic parameter acquisition means for acquiring the characteristic parameters by analyzing a read image of the characteristic parameter acquisition chart (100;200) acquired by the image reading means; halftone process generation means for generating halftone processing rules that define halftone processes used in the printing system based on the characteristic parameters acquired by the characteristic parameter acquisition means ; setting means for setting a parameter that is related to a system error assumed in a case where printing is performed by the printing system and includes the characteristic parameters; means for generating a simulation image in which the system error indicated by the parameter is reflected; and image quality evaluation means for evaluating image quality of the simulation image in which the system error is reflected, wherein the system error includes a characteristic error expected to exhibit reproducibility as the characteristics of the printing system, and a random system error as an irregularly changed error, and the halftone process generation means generates the halftone processing rule based on a simulation image in which evaluation falls in a target range. <EOS>
