<P>PROBLEM TO BE SOLVED: To provide a marking signal control method in printed matter defect inspection, capable of performing marking at a defect position with positioning accuracy in consideration of the operation delay of a marking device and a printed matter conveyance speed. <P>SOLUTION: A marking signal control method in printed matter defect inspection is the method for allowing a marking device to perform marking at a defect position when a defect is detected after the inspection of a printed matter where printing is performed on a base material, including: obtaining a printed matter conveyance amount within the operation delay time of the marking device from the acquisition of a marking signal to the performance of the marking on the basis of the operation delay time of the marking device and a printed matter conveyance speed; obtaining a delay amount for original delay by subtracting the printed matter conveyance amount within the operation delay time of the marking device from a unique delay amount indicating a distance from a predetermined inspection position to the marking device; and operating the marking device on the basis of the delay amount for original delay. <P>COPYRIGHT: (C)2013,JPO&INPIT |
