Abstract
Cigarettes can be coded and identified at a later time by perforating the tipping paper to provide air dilution characteristics to the cigarette. The perforation pattern employed has a unique, predetermined configuration which is recorded and used at a later time for identifying particular set of cigarettes. A different perforation pattern can be applied to different sets of cigarettes at various times, locations, etc. Thus, the manufacturer of air dilution cigarettes can trace coded cigarettes in order to improve quality control.
