Inkjet recording system and print information correction method

In the present invention, prescribed information comprising dots formed with ink discharged to a printing object is printed on the printing object, the prescribed information is imaged, and a printing area is detected from an image obtained by imaging the prescribed information. A reference position grid is generated in which a reference point, which is a reference point for a hit position of a check point, is added to each of dot regions obtained by dividing a print region into predetermined dot regions. The hit position is checked on the basis of a superimposed image obtained by superimposing a print area and a reference position grid, and a determination level reference table for determining the degree of deviation of the hit position of a point with respect to the position of a reference point. A feedback signal for correcting the hit position is generated and output to the inkjet printer on the basis of the reading and checking results and correction data that defines the correction amount of the dots co
