How much is the captain's salary of Heidelberg four-color machine? Will there be too many captains in recent years and will the salary be reduced?

Heidelberg will turn on the machine for four turns to 4000-6000, six turns to 3000-5000, personal ability is 2500-3500, and the upper and lower lines are 500- 1000. I believe there will be many new captains in Nantong in the next few years, because there are many people joining this industry and some talents. Salary reduction should not be, unless the country has some corresponding certificates.
