Nip rings, transport rollers, cutting rings, with and without coating

Electrostatic assist cannot be used for metallic inks due to the risk of short circuits or sparks. To enable dissipation of static electricity, we offer antistatic coatings. The PressoGraf range for classical rotogravure presses comes in the following variants, each with their own specific qualities. All versions are by default antistatic and so reduce fire risk as a result of sparkover. The impression roll coverings or sleeves are available for the applications of decorative printing, cardboard printing and flexible packaging.

Rotogravure (also known as gravure) is a form of printing that utilizes an engraved cylinder and an elastomer coated impression roller. The engraved image on the cylinder picks up the ink which is transferred to the web using pressure. Roller and sleeve covering play a crucial role in the rotogravure printing process as they ensure an even and maximum coverage of the ink in order to achieve the highest printing quality. Hannecard has been active and specialized in roller and sleeve coverings for gravure printing for more than 50 years now to ensure a perfect printing quality.

Electrostatic assist is used in rotogravure printing to prevent missing dots and ensure higher-quality images with high ink and color density. To guarantee the best and homogenous printing results ever seen, Hannecard developed the unique solutions HanneResist & HanneVision where carbon nano particles are added to its elastomer coatings. Thanks to this unique combination a more homogeneous electric field is generated, offering more accurate attraction of ink on the printed medium and resulting in a superior printing quality. This new technology also better controls the electric charge submitted to the roller, thus lowering the risks for over-charging and sparks. Our HanneResist & HanneVision covering solutions are suited for the decor & cardboard packaging (especially cigarette packaging) printing industry and complies with all electrostatic assist systems (top loading, direct charge (core charging) and side loading)
