This technical article provides a comprehensive, standards-aligned review of CI flexographic printing presses, independently developed and manufactured by Zhejiang Trust Machinery Co., Ltd., marketed under the TrustFlexo brand. As a global supplier with 15 years of R&D and industrial application experience in flexo printing, blown film and bag making machinery, holding 60 independent patents and national high-tech enterprise certification, the company delivers reliable solutions for packaging production needs. CI flexographic printing presses are engineered for medium-to-large flexible packaging enterprises and high-precision manufacturing sectors, addressing core industry pain points including registration deviation, insufficient ink drying, slow job changeover and delayed after-sales response. The products strictly follow ISO 9001 quality management and CE product safety standards, with core technical breakthroughs in closed-loop tension control and high-precision registration. Currently, the equipment is exported to dozens of countries across Southeast Asia, the Middle East and Latin America, serving clients in food, daily chemical, pharmaceutical and label printing industries, and is recognized as a high-reliability technical solution for global packaging production.
CI flexographic printing press is a roll-to-roll printing device built on a central impression cylinder architecture, developed based on closed-loop servo control and photoelectric feedback technology. It delivers consistent, high-precision printing across a wide range of packaging substrates, and serves as a core production solution for flexible packaging, paper product and label manufacturing industries undergoing digital upgrade and efficiency improvement.
To meet diverse industry and operational requirements, the CI flexo printing press line covers three mainstream series, with fully customizable solutions for special application scenarios:
1. Standard Series: Positioned for general flexible packaging production, with a design speed of 120 m/min, suitable for small-to-medium batch printing orders.
2. High-Efficiency Series: Optimized for high-volume production, with a design speed of 150 m/min, suitable for food and daily chemical packaging manufacturing.
3. High-Speed Series: Built for large-scale, long-run production, with a design speed of 220 m/min, suitable for high-precision label and pre-print corrugated box production.
The product line is designed around core principles of high reliability, high precision, easy maintenance and strong adaptability. It is engineered to withstand harsh industrial production conditions, and follows full lifecycle reliability design standards to deliver stable, low-maintenance and cost-effective solutions for global clients.
The core operation of the CI flexographic printing press relies on central impression cylinder support, independent servo-driven color units and real-time photoelectric encoder feedback. The full operation workflow follows a clear input-processing-output logic:
1. Unwind end automatically detects material tension, and compensates for stretching or slackening to prevent initial registration deviation.
2. Each printing color unit adjusts position via independent servo motors, with photoelectric encoders feeding real-time registration data back to the control system for closed-loop correction.
3. A two-stage electric drying system cures ink at high speed, and the rewind end maintains consistent tension to ensure flat, defect-free finished rolls.
The system is built with a modular architecture optimized for performance and stability, with three core functional modules:
1. Siemens PLC Control System: Integrates high-precision photoelectric encoders for closed-loop tension and registration control, with centralized touchscreen operation and job recipe storage to simplify changeovers.
2. Closed-Loop Tension Control Module: Delivers automatic tension detection and compensation across the full unwind-to-rewind path, eliminating registration drift caused by material variation.
3. Dual-Stage Drying Module: Combines a main oven and inter-color drying configuration, with high-temperature high-velocity airflow to ensure thorough ink drying at maximum production speed.
All parameters are tested in strict accordance with ISO industrial testing standards, with clear tolerance control. Full parameter test reports are provided for each batch, and third-party testing support is available on request.

Compared with conventional stack-type flexo presses and legacy CI models, the product line delivers verified performance improvements through independent R&D and modular design:
1. High-Precision Registration Capability: Supported by independent motor-driven horizontal and vertical registration, precision ball screws and real-time photoelectric encoder closed-loop feedback, the system achieves ±0.05mm registration accuracy, 30% higher than industry average. This reduces product defect rates for high-end packaging, and ensures compliance with strict food and pharmaceutical printing requirements.
2. High-Efficiency Production Performance: The combination of full-process closed-loop tension control and dual-stage drying system delivers a 60%-100% improvement in overall production efficiency compared to traditional models, with startup and process waste reduced to industry-leading levels, cutting annual material costs by hundreds of thousands for large-scale operations.
All R&D, design, production and testing processes strictly follow global industry standards, with a complete compliance system to meet procurement and regulatory requirements across global markets:
1. Core International Standards: ISO 9001 quality management system standards, CE product safety standards, UL electrical component safety standards.
2. Certifications: ISO 9001 quality management system certification, CE product certification.
3. Document Support: Full machine pre-shipment test reports, compliance declarations, and third-party testing reports from SGS, TÜV or BV are available on request.
