This technical article provides a comprehensive, standard-compliant analysis of Central Impression (CI) flexographic printing presses developed and manufactured by Zhejiang Trust Machinery Co., Ltd. With over 15 years of R&D and industrial application experience in flexo printing, blown film, and bag making machinery, we are a global leading supplier dedicated to advancing industry technology. Our CI flexo printing presses are tailored for medium-to-large flexible packaging enterprises and high-precision sectors, effectively solving core industry pain points including registration drift at high speeds, ink clogging, and inefficient production changeovers. Strictly adhering to ISO 9001 quality management standards and CE certification requirements, our products achieve industry-leading ±0.05mm registration accuracy and full-process closed-loop tension control, with deployments across dozens of countries in Southeast Asia, the Middle East, and Latin America.
A Central Impression (CI) flexographic printing press is a high-speed, multi-color printing system that uses a large central cylinder to support substrate feeding and ensure consistent pressure across all printing units, enabling precise, synchronized printing on flexible packaging materials. As a core solution in the flexible packaging industry, it is indispensable for meeting high-volume, high-precision printing demands in food, pharmaceutical, and label sectors. To meet diverse operational needs, our CI flexo presses include three main series: High-Speed CI Series (design speed up to 220 m/min) for large-batch production, Standard CI Series (150 m/min design speed) for balanced precision and efficiency, and Entry-Level CI Series (120 m/min design speed) for cost-effective, reliable performance. Our product design centers on precision, reliability, and deep customization, adhering to full-life-cycle reliability standards to deliver stable, low-maintenance solutions for industrial scenarios.
The core working principle of our CI flexo printing press relies on a central impression cylinder to maintain uniform pressure across all printing units, paired with a Siemens full-servo system for precise motion control. The complete operational flow includes: 1. Unwind unit with closed-loop tension control to stabilize substrate feeding and prevent stretching; 2. Independent servo-driven printing units with real-time photoelectric encoder feedback for accurate color registration; 3. Dual-stage electric drying system to ensure thorough ink drying at high speeds; 4. Rewind unit with tension compensation to maintain substrate integrity. Key innovative architecture modules include the Siemens PLC centralized control system, which integrates job recipe storage and data tracking, and the anti-clogging anilox roller design that automatically rotates during machine stops to eliminate ink drying issues. Compared to traditional mechanical-shaft-driven presses, our full-servo system reduces registration errors by over 90% and cuts changeover time by 60%, addressing long-standing industry pain points.
All parameters are tested strictly according to ISO and CE standards, with clear test conditions and tolerance controls. Key specifications include: Core Performance: Design speed ranges from 120–220 m/min (actual production 30–170 m/min depending on substrate), maximum material width 1200 mm (customizable to 1400/1600 mm), print repeat length 360–1000 mm, and ±0.05mm registration accuracy. System Configuration: Siemens full-servo control system, dual-stage electric drying oven, closed-chamber doctor blade system, and optional BST online inspection. Material Compatibility: Supports PE, OPP, BOPP, PET films, paper, non-woven fabrics, aluminum foils, and composite materials. Customization is available for special width, color unit, or functional requirements.
1. Industry-Leading Registration Accuracy: Achieving ±0.05mm horizontal and vertical registration, supported by independent servo motors and photoelectric encoder closed-loop feedback, meets strict requirements for food and pharmaceutical packaging, reducing material waste by up to 15%. 2. Reliable Core Components: Equipped with Siemens full-servo systems, NSK bearings, and Leuze sensors, ensuring long-term operational stability with a 60% lower failure rate compared to domestic-assembled models. 3. Efficient Production Design: Anti-clogging anilox rollers and sleeve quick-change structure reduce downtime by 40% and cut changeover time to less than 30 minutes per job.
Our CI flexo printing presses are developed, designed, and manufactured in strict compliance with ISO 9001 quality management system standards and EN 60204-1 mechanical safety standards. Products hold CE certification for EU market access, and all electrical components meet CE/UL standards. We can provide full documentation including factory test reports, CE conformity declarations, and third-party inspection reports upon request.
