A press assistant, also called a press operator, supervises and operates the press machine that produces print publications like newspapers, magazines, and books. Their job duties are to run the printing press machine, load supplies like ink and paper, and adjust the settings to ensure quality results. They also have to manage inventory and meet deadlines. The qualifications for a career as a press assistant are a high school diploma or GED and voluntary postsecondary certification in print technology. On-the-job training provides you with the skills and experience you need to operate a press machine on your own.
