Winding drum variable digital printing data intelligent extraction, process quality intelligent monitoring and intelligent management method

The invention discloses an intelligent winding drum variable digital printing data extraction, process monitoring and management method. The method comprises the steps of performing production makeupand printing; performing variable data jet printing, and positioning abnormal variable data jet codes; generating a mother volume data packet; slitting the mother roll, and detecting the product quality; marking the position of an abnormal product; after slitting is completed, generating a data packet of each sub-volume; and rewinding the sub-volume containing the abnormal product. According to the invention, the sub-rolls without abnormal products can cancel the rewinding process, and shorten the processing flow. Arranging the positioning trigger mark can accurately position the position of each variable digital spray code, and detection is separated from rewinding. Shutdown processing is not needed when abnormal products are detected, so that the detection efficiency is improved. Bar codes are printed on each ro
