Product overview
The electrostatic-assist rotogravure printing machine ESA-RG3000 integrates a controlled high-voltage electrostatic system to improve ink transfer from gravure cells onto difficult substrates. The design enables photographic-quality printing on rough, porous or uneven materials while lowering mechanical impression pressure and reducing gravure cylinder wear.

Key features

• Electrostatic assist (controlled DC high-voltage) to enhance ink pick-up and transfer from gravure cells.
• Reduced mechanical impression pressure to extend gravure cylinder and impression roller service life.
• High-speed production capability with stable color density and low ΔE variation.
• Dedicated safety systems for high-voltage operation including arc detection and current-limiting protections.
• Compatible with a wide range of film and paper substrates.

Applications

• Flexible packaging: high-end food and brand packaging on PET, BOPP and similar films requiring sharp graphics and barcode accuracy.
• Decorative laminate production: realistic pattern printing (e.g., wood grain) on rough decorative paper and laminates.
• Specialty paper manufacturing: consistent printing on porous or highly absorbent papers.

Technology highlights
The electrostatic assist system creates an attractive force that pulls ink from gravure cells onto the substrate, enabling near-complete ink discharge even in low-tone areas (1%–10%). The system maintains a uniform electrical field across the web width via a conductive impression roller and tightly controlled voltage settings to ensure repeatable results.
