Atmospheric emissions from hot-metal typesetting operations are investigated in this screening study. Three letterpress printing processes entail the use of hot metal: linotype, monotype, and stereotype. These processes are described and potential emission sources identified. Techniques for control of emissions include use of Rotoclones, wet scrubbers, filters, and electrostatic precipitators. Estimated capital costs and annualized operating and maintenance costs of these devices are presented. Three hot-metal printing operations in which emissions are well-controlled are described in detail. Annual estimates of total nationwide emissions from hot metal printing amount to approximately 1370 tons of particulate including 480 tons of lead. It is projected that no new hot metal type printing facilities will start operation and that emissions of lead from the printing industry will steadily decrease by about 8 percent per year until 1986.
