Engineered for packaging converters and commercial printers, our CI flexo printing machine for paper delivers precise color-to-color registration and consistent ink transfer on a wide range of paper-based substrates, including lightweight tissues, coated paper, kraft, and paperboard. The machine platform is available in several configurations to match different production requirements. The High speed CI flexo printing machine is optimized for high-volume paper bag and cup production, achieving rapid changeovers and minimal downtime. For larger format cartonboard and paper packaging, the Wide web CI flexo printing machine provides expanded web width handling with stable tension control. Additionally, as a CI flexo printing machine for flexible packaging, this system excels at printing on paper laminates and flexible paper structures, while the CI flexo printing machine for plastic film configuration demonstrates the same core engineering adapted for film applications, ensuring a versatile solution for mixed paper and film converting lines. Each press is built around a central impression drum that minimizes substrate distortion and ensures excellent registration at all operating speeds.
The CI flexo printing machine for paper features a precision-ground central impression drum with a diameter of 1,200 mm, providing a stable printing foundation for demanding paper applications. Up to 10 flexo printing units can be configured, each driven by an independent AC servo motor for precise speed synchronization and repeatable print quality. The machine accepts a wide range of paper substrates, from 30 g/m² lightweight tissue to 350 g/m² paperboard, and is equipped with a closed-loop tension control system that maintains stable web tension across the full speed range. Key parameters and optional configurations are detailed below.

For drying, the machine offers hot air, UV, or LED-UV inter-station dryers with independent temperature control and automatic nozzle positioning. The enclosed doctor blade chamber maintains consistent ink viscosity and reduces solvent evaporation, while the ceramic anilox rolls with 200 to 800 LPI ensure fine line and solid coverage. The press is controlled by a PLC system with a 15-inch color touchscreen, enabling recipe storage for up to 500 jobs and remote diagnostics through Ethernet. Additional options include a corona treater, web cleaning unit, static eliminator, and automatic viscosity control, which can be retrofitted without structural modifications.
