Abstract: The reading timing determination unit determines a timing at which identification marks such as print bar codes should be read. The reading unit reads identification marks in accordance with the timing to provide identification mark data in a numerical form. The discrimination unit compares identification mark data with data value of an identification mark to be primarily printed to judge whether or not the identification mark is correctly printed. The signal generation unit produces a notifying signal when it is judged that the identification mark is not correctly printed. In this way, this apparatus tests whether or not identification marks successively printed on a moving body in the form of sheet by the printing machine are correctly printed.
