Electrostatic Printing Assist GNH63 to eliminate missing dots - gravure printing

Description

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 into the conductive layer of the impression roller coating via the impression roller bar. The nip voltage (300 to 900V 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 2-layer impression roller is used for the ESA Top Loading systems GNH63. The impression roller guarantees the even distribution of the charge in the printing nip.
