Problems solved by technology

In addition to the slow speed of manual inspection, which requires a lot of manpower, material resources and site resources, human eyes are prone to fatigue due to long-term repetitive work. At this time, some serious waste products will even be released.
Secondly, during manual inspection, only the first and last numbers of a group of products can be randomly checked, and it is impossible to check one by one, and it is easy to miss the inspection of waste products
This will bring serious losses to printing manufacturers and users, and cause extremely bad social impact
