The film describes printing as essential to education, religion, business, and government, and as a major national industry that makes accumulated knowledge widely available. Inside printing shops, workers mark up copy, set display type by hand, operate linotype and monotype machines, pull proofs, correct errors, assemble pages, and prepare forms for the press. Letterpress production is divided into composition, presswork, and bindery work, while demonstrations show how metal type is cast and proofs are checked. Small job presses, offset equipment, cylinder presses, and high-speed rotary presses demonstrate the machinery used for different products and print runs.
Press operators adjust pressure and ink, match machines to paper, and oversee costly equipment, so their work requires mechanical knowledge, accuracy, good eyesight, and close attention. Vocational students begin with hand composition and subjects such as spelling, punctuation, proofreading, word division, and printer’s arithmetic before moving to presses or linotype operation. Apprenticeship and on-the-job instruction are described as the main routes into the trade, with vocational school helping students test their interest and prepare for specialized work. Addressing young viewers, the closing section says that printing offers year-round employment, stable wages, advancement, and work for both men and women, and urges them to investigate the occupation.
