Gravable Printing Plate Surface Defect Intelligent Detection Method

The author visited many gravure printing plate-making enterprises in China and found that in the fierce market competition environment, enterprises have gradually changed their approaches to improving their competitiveness. They used to upgrade their competitiveness by purchasing high-value automation equipment and other heavy assets, and they gradually changed to purchase or upgrade enterprise operation management system software and improve employees’ abilities. The core competitiveness has been improved by improving the soft power of knowledge structure, or by continuously optimizing the technology and carrying out the “equipment substitution program”. In such a case, the development and productization of “gravity plate surface defect intelligent detection system” has attracted the attention of many gravure printing companies domestically and overseas, and has great market prospects. The detection system is divided into five modules, namely the plate roller bearing module, the plate roller wiping module, the scanning detection module, the coding mark module, and the system control module. The plated roll is loaded onto the inspection device, and every module are at the working state from the initial state. The surface wipe module starts working, after which the scan detection module starts the first scan. By software calculation, non-defects are excluded from suspected defects, and true defects are confirmed. The coding mark module marks the real defects, and after the detection and coding process are finished, every module returns to the initial position. The plate roller is removed from the inspection device to complete the inspection task.
