Guides to Pollution Prevention: The Commercial Printing Industry
Commercial printers, who include lithographers, gravure printers, flexographers, and letterpress and screen printers, generate a variety of wastes during printing operations. The manual largely addresses the wastes and waste minimization options for offset lithographers. Waste that can be disposed of in trash include some waste paper; film; empty containers; used blankets; and damaged products and other items. The wastes result from image processing, plate making, proof making, printing, and finishing processes. Another form of waste - wastewater - results from image processing, plate making, and printing processes. Equipment cleaning wastes and air emissions are other categories of waste. Much of the waste paper generated can be recycled.
