Printed matter defect detection system and method

Abstract

The invention discloses a printed matter defect detection system and method, and belongs to the technical field of printed matter full-picture quality detection. The printed matter defect detection system comprises a numbering unit, a vision detection device, a controller, a marking unit and a rejecting device. The numbering unit conducts sequence numbering on to-be-printed products on a production line. The numbering unit is connected with the controller. The vision detection device is installed after the printing production step is conducted. The vision detection device is connected with the input end of the controller, and printed image information collected by the vision detection device is sent to the controller for defect analysis. The marking unit recording the defected printed products is connected with the controller. The rejecting device is connected to the output end of the controller and installed on a device completing printing. The printed matter defect detection system and method solve the problem that because printing is stopped halfway for defect rejection and good product supplementation, time is consumed, have the beneficial effect of saving time, and are simple in structure and easy to improve and use.

Description

technical field [0001] The invention belongs to the technical field of full-screen quality inspection of printed matter, relates to the direction of defect detection of printed matter images, and in particular relates to a printed matter defect detection system and method thereof. Background technique [0002] Whether it is traditional printing or digital printing, people have to face a very important problem in the printing process, which is the quality inspection and control of printed matter. The speed of modern printing machines is constantly increasing, which puts forward higher requirements for the quality inspection and control of printed matter. Traditional printing quality inspection and control methods can no longer meet and guarantee the requirements of modern printing with high quality, high efficiency and low cost. Therefore, it is the dream of printing manufacturers to realize the automatic detection of printed matter quality. It is not only the basis for digi...

Problems solved by technology

[0004] According to the deficiencies in the prior art above, the technical problem to be solved by the present invention is to propose a printed matter defect detection system and method thereof, which records the number of each printed matter by numbering and records the number when a defective printed matter is detected. After printing is completed , to take out defective printed products, no need to stop in the middle of printing to pick up defective printed products, which saves a lot of working time, solves the time-consuming problem of stopping to remove defects in the middle of printing, and replenishing good products. It has the advantage of saving time, simple structure, and easy to improve. Simple to use
