“High voltage on a sharp emitter in proximity to ground is the basis for creating ions, and keeping both the emitter and the ground free of slitter dust, oil, and other contaminants found in the printing process is important,” adds Patterson.

Surface contamination should not be a problem in a well-run printing operation. The equipment to address this problem is readily available from a number of suppliers. The key is to use their expertise to ensure that the right process is implemented, and then perform proper maintenance and housekeeping to keep it running at effective performance levels. pP
