Hannepearl covering: nanotechnology revolutionizes ESA roller and sleeve coverings

With HannePearl, Hannecard revolutionizes roller and sleeve coverings for cardboard packaging with electrostatic assist (ESA). Electrostatic assist is used in rotogravure printing of cardboard packaging to prevent missing dots and ensure higher-quality images with high ink and color density. Thanks to the carbon nanoparticles in the HannePearl roller and sleeve coverings, a more homogeneous electric field is generated on the impression roll, eliminating missing dots from the ink transfer, from printing nip to the substrate.
