Total organics, carbon dioxide, carbon monoxide and methane emissions were measured from offset printing and metal decorating operation. A reliable yet simple grab sampling method was developed along with the appropriate analytical technique, which uses gas chromatography and a flame ionization detector. The effects of plant process variables on emissions were evaluated and equations based on operating parameters such as press speed, ink coverage, solvent content, dryer type, sheet size, and coating thickness were then developed to calculate emission rates. Test results are presented for web offset and metal decorating operations using both catalytic and thermal afterburners over a range of incineration temperatures. Recent developments and changes being investigated within the industry for reducing air pollution, including process modifications, are discussed in the report to the extent that information was available.
