The research of printing´s image defect inspection based on machine vision

There may be printing´s image defect in printing during the course of print. It is absolutely necessary for Print Corporation to inspect printing with defect. Traditionary printing defect inspection is usually completed by manpower, whose inspect quality is instability, and inspect efficiency is low. The paper proposed a method of printing´s image defect inspection based on machine vision, sot up an experiment system. Familiar printing defects such as filar defects, zonal defects, punctuate defects and block defects are inspected in the experiment, which proves practicability of the method and has value of extend application.
