You operated strike-on composition equipment — typesetting machines that produced typeset output by directly striking characters onto paper or film — Selectric Composer, IBM MT/SC, or similar systems used in the era between hot metal and phototypesetting.
The strike-on machine combined typewriter-like operation with proportional typesetting output — operators worked from marked-up copy, applying typographic codes for font and spacing, producing typeset pages directly on paper or film without the molten-metal infrastructure of linecasters. Pages set and proof accuracy anchored the operating measures.
What complicated the work was the precision required across typography decisions — strike-on composition handled proportional spacing, font changes, and column-justified output, and operators applied formatting at the keystroke level. Industry variance shaped the role: commercial printers and small-publication shops ran strike-on composition through the 1960s and 1970s; smaller offices used strike-on equipment for in-house publications.
The role tended to fit those comfortable with skilled typography work and patient with technical formatting under production pressure. Many operators transitioned into phototypesetting and later desktop publishing as the industry shifted. The trade-off was the gradual displacement by phototypesetting and computer-based composition through the 1970s and 1980s, with most strike-on operations retired by the mid-1980s across the commercial-printing industry.
