GNN75 Core Charging


The infeed paper or film web is discharged by the discharge bar to eliminate any existing residual static charges. The nip voltage required in the printing nip is transferred via the bearing of the impression roller into the conductive layer of the impression roller coating by a ball spring contact. The nip voltage (300 to 900 V DC) causes the ink to transfer from the cells to the substrate with point-to-point accuracy and without high impression roller pressure. The discharge bar mounted on the outlet side eliminates any residual charges on the surface of paper or the film. A 1-layer impression roller is used for the ESA GNN75 system. The precisely defined coating guarantees the even distribution of the charge in the printing nip. The GNN75 system can only be delivered in arrangement with the press manufacturer.
