In this study, we listed the VOCs focusing on ozone precursors emitted from printing shops in urban areas. The emission characteristics of the VOCs from workplaces were evaluated in terms of the used inks. As a result of field measurements, more than 80% of detected VOCs showed high values of photochemical ozone creation potential (POCP). The main species were aromatic hydrocarbons such as ethylbenzene, toluene, ethyltoluene, xylene, trimethylbenzene and their isomers, and paraffin hydrocarbons such as nonane, decane, and octane. Comparative examination between pristine ink and the printing process revealed the emission of hydrocarbons with 8 to 12 carbons such as o-xylene to n-dodecane from the used inks and with 3 to 7 carbons such as acetone to 3-methylhexane from the printing process. The major contributors to ozone production in printing industries were toluene (12.2%), heptane (7.43%), and 1,2,3-trimethylbenzene (7.21%) in every step.
