Abstract
A study was conducted examining volatile organic compound (VOC) emission factors associated with offset printing. Ventilation rates, VOC levels, and printing activities and processes were evaluated at three offset printing facilities. Ventilation and air concentration data were used in two mass balance models to determine VOC emission rates for each sampling period. These rates were then compared with process variables for the same sampling period. VOC emission rates were most closely correlated with the use of cleaning solvents. Single and multiple variable regression analyses were used to develop emission factors relating cleaning activities to the mass of VOCs released. When calculated on a mass VOC emitted/area printed basis, the amount of VOCs emitted by the smallest print shop was 12 times that of the other two facilities. The hourly average total VOC concentrations at all three sites were below acceptable limits. Both mass balance models gave good results for short term emission rates. The authors conclude that the emission factors determined in this study have multiple applications to the printing industry.
