What is the main job of recruiting and proofing in lighting factory?

After designing the drawings, give them to the proofing person, who is responsible for turning the drawings into objects; Because many new parts involved in this project are new parts that have never appeared in the market, this piece of work is very difficult and requires close cooperation from people in various departments, so it must be a person with strong communication skills.
