摘要：In order to improve read stability, a printing condition is set based on not visual read of a user, but read with an optical information reading apparatus. A printing quality evaluation apparatus includes: an image acquiring section that acquires an image; a symbol extracting section that extracts the symbol in which the printing quality can be evaluated from the captured images acquired by the image acquiring section; a printing quality evaluation section that evaluates the printing quality of the symbol extracted by the symbol extracting section; an identification information recognition section that recognizes the identification information identifying each printing condition of the symbol; and an evaluation output section that outputs the identification information, which is recognized by the identification information recognition section, and an evaluation result of the printing quality of the printing quality evaluation section according to the symbol extracted by the symbol extracting section.

主权项：1. A printing quality evaluation system comprising: a printing condition setting device that sets a printing condition in order to print a plurality of symbols having different printing conditions in a printing target with a laser marking apparatus; and a printing quality evaluation apparatus that evaluates printing quality of each symbol based on captured images of the plurality of symbols having the different printing conditions, the plurality of symbols being printed in the printing target with the laser marking apparatus based on printing data that is generated according to the printing conditions set with the printing condition setting device, wherein the printing condition setting device includes: a parameter setting section that sets a variable parameter varying the printing condition and a fixed parameter as a plurality of printing parameters constituting the printing conditions;a printing condition generating section that substitutes a plurality of different parameter values for the variable parameter set by the parameter setting section while substituting fixed values for the fixed parameter set by the parameter setting section, thereby generating the plurality of different printing conditions;a printing data generation section that generates printing data including the plurality of symbols, each of the symbols corresponding to each of the plurality of different printing conditions generated by the printing condition generating section, each of the symbols being correlated with an identification information identifying a parameter value on the variable parameter included in the printing condition and being decoded or optically recognized as the identification information by the printing quality evaluation apparatus; anda printing data output section that transmits the plurality of symbols generated by the printing data generation section to the laser marking apparatus, thereby the plurality of symbols being printed two-dimensionally in the printing target with the laser marking apparatus, and the printing quality evaluation apparatus includes: an image acquiring section that acquires the captured image including the plurality of symbols printed in the printing target, the captured image being captured with resolution at which the printing quality of the symbol is evaluated;a symbol extracting section that extracts the symbol in which the printing quality is evaluated from the captured images acquired by the image acquiring section;a printing quality evaluation section that evaluates the printing quality of the symbol extracted by the symbol extracting section;an identification information recognition section that recognizes the identification information by decoding or optically recognizing the symbol extracted by the symbol extracting section, the identification information identifying a parameter value on the variable parameter included in the printing condition, printing condition corresponding to the symbol extracted by the symbol extracting section; andan evaluation output section that outputs an evaluation result of the printing quality evaluated by the printing quality evaluation section and the identification information recognized by the identification information recognition section according to the symbol extracted by the symbol extracting section.
