The sheet pile at the feeder section of the printing machine may have a static charge which causes the sheet (substrate) to stick to the pile and misfed into the machine. Once the squeegee has realized its printing stroke and the screen is lifted, the substrate may stick to the screen, causing smearing. The substrate may also stick electrostatically to the screen bed and cause misalignment. Misbehavior on its path through the dryer, and incorrect piling at the delivery, attraction of airborne contaminants are all problems which Simco-Ion products can resolve, preventing irritation and machine stops.
