Control Techniques Guidelines for Offset Lithographic Printing and Letterpress Printing
This control techniques guidance (CTG) addresses both the offset lithographic printing industry and the letterpress printing industry. Although offset lithographic printing and letterpress printing are two distinct product categories on the section 183(e) list, they have many similarities in the types of inks and cleaning materials used, the sources of VOC emissions, and the controls available to address those emissions. We therefore address both categories in this CTG. The CTG is intended to provide state and local air pollution control authorities information that should assist them in determining reasonably available control technologies for volatile organic compounds (VOCs) for offset lithographic printing and letterpress printing. In developing this CTG, EPA, among other things, evaluated the sources of VOC emissions from these printing industries and the available control approaches for addressing these emissions, including the costs of such approaches. Based on available information and data, EPA provides recommendations for RACT for offset lithographic printing and letterpress printing.
