The qualifications to get a prepress job depend on your specific responsibilities. If you are an artist, digital platemaker, or graphics technician, you are responsible for designing and setting images using digital tools, so you should have a strong working knowledge of software like QuarkXPress and Adobe InDesign. Prepress operators need to have a high school diploma or GED certificate and several years of training in a printing operation. You can also go to a vocational school or community college to get more technical experience. Important skills include an eye for detail and mechanical aptitude.
