What does the printing press do?

The work content of the third-hand printer is generally to check the feeder, load paper, etc.

Generally speaking: an offset printing press team is composed of a foreman, a deputy (second-hand), a third-hand, and a fourth-hand (apprentice). The captain is responsible for operating the console, calibrating plates and colors, controlling product quality, and directing the entire crew to coordinate organically and complete orders. The second-hand one is the captain's right and left hand, loading plates, etc. Third-hand workers usually watch feeders, load paper, etc. Considering that the value of machinery and equipment is very high, misoperation can easily cause damage to the machine and personal safety. Generally, the captain will ask the apprentice to do some groceries first, such as sorting out broken pieces, fetching water, etc. Alcohol, cleaning, learning how to install paper, and later, washing erasers, etc., after a normal period of time, it is transferred to third hand, and then second hand.
