Overview
The Zhirui 3.0plus rotogravure printing press is a production-grade solution for flexible plastic packaging. Available widths: 1050 mm and 1250 mm. Compatible with OPP, BOPP, CPP, PET, PE, PVC and Nylon substrates. Typical configured speed: 150–400 m/min (page lists 350 m/min as typical). Color capability: 6 to 12 colors. Designed for long production runs in food, pharmaceutical, hygiene and label applications.

What Makes Our Gravure Printing Technology Stand Out?
The press uses engraved copper-plated steel cylinders with precisely defined cells to transfer inks with high color density and continuous-tone reproduction. The mechanical and control systems focus on color stability, repeatability and substrate handling to meet demanding packaging standards, including food-contact requirements where applicable.

Key Technical Specifications

• Mechanical speed: 150–400 m/min (typical 350 m/min)
• Registration accuracy: ±0.10 mm (ARC system)
• Tension control range: 3–30 kg (four-zone: unwind, in-feed, printing unit, rewind)
• Drying system: Intelligent hot-air tunnel with LEL monitoring
• Compatible substrates: OPP, BOPP, CPP, PET, PE, PVC, Nylon
• Ink types: Solvent-based and water-based (water-based requires specific modifications)
• Color registration drive: Electronic Line Shaft (ELS)
• Standards & certification: ISO 12647-6, CE

Applications Across Industries

• Food & Beverage packaging: Suitable for retortable pouches and ready-meal films; inks and process controls support sterilization and high-temperature resistance.
• Shrink sleeve labels: Precise tension and drying control to prevent pre-shrink and ensure uniform ink application.
• Pharmaceutical & hygiene products: Low-migration processes for cold-form foils and hygiene films to meet regulatory and skin-contact requirements.

Advanced Quality Control Features

• Auto-registration systems to stabilize color at high speeds and reduce substrate waste.
• Four-zone tension control to maintain web stability on extensible films and prevent gauge variation.
• Solvent-residue monitoring with gas chromatography to keep residual solvent levels within food-grade limits (below 5 mg/m²).
• Precision doctor blade systems to minimize streaking and haze during long runs.

Frequently Asked Questions (selected)

• How is static electricity handled during high-speed printing? Active ESD bars and conductive brushes at unwind/rewind stations plus humidity control prevent static-related defects and fire risks.
• Can the press use water-based inks on plastics? Yes, with modifications such as increased airflow in drying tunnels, longer dwell times and shallow-cell cylinders to optimize water-based ink performance.
• What determines engraved cylinder lifespan? Cylinder life depends on chrome plating hardness (~1000 HV), doctor blade settings and ink abrasiveness; typical life under optimal conditions is 3–5 million rotations with routine surface checks.
• How are telescoping issues at rewind solved? Software-applied taper tension curves and calibrated load cells reduce torque variation while uniform lay-on roller pressure prevents telescoping.
• Impact of viscosity control on print quality? Automatic viscosity controllers monitor and adjust solvent levels continuously to maintain consistent flow and color density, preventing print defects.
