Inkjet recording system and print information correction method

An inkjet recording system comprising:

• an inkjet printer for ejecting ink onto a print target and printing predetermined information comprising dots formed by the ejected ink onto the print target;
• a camera capturing images of the predetermined information printed on the print target;
• a detection unit for detecting the printing area of the predetermined information from the image captured the predetermined information,
• a criteria position grid unit for dividing the detected printing area into predetermined dot areas and generating a criteria position grid in which each of the divided dot areas is assigned with a dot as a criteria for inspecting the landing position;
• a reading determination unit for inspecting the dot landing position relative to the criteria dot position based on a superimposed image of the printing area and the criteria position grid and a determination grade criteria table to determine the degree of displacement of the dot landing position relative to the criteria dot position,
• a processing unit including a dot position correction unit for generating a feedback signal for correcting the dot landing position based on the result of the inspection and the correction data defining the correction amount of the dots comprising the printing area determined according to the degree of the displacement and outputting to the inkjet printer,
• wherein the inkjet printer ejects ink on the print target based on the corrected dot landing position obtained from the feedback signal.
