    • Central Impression Flexo Printing Technology

    Stable, High-Quality Printing for Flexible Packaging

    Changhong CI Flexo Printing Machines are designed for stable, high-quality printing on plastic films, paper, nonwoven fabrics, aluminum foil, PP woven materials, and other roll-to-roll substrates. The central impression structure provides consistent substrate support during printing, helping reduce material stretching and maintain accurate color registration.

    The machine combines precise web tension control, advanced printing units, automatic pressure adjustment, and centralized drying to support efficient continuous production across a wide range of packaging applications.

    CHANGHONG Key Features

    Central Impression Printing

    The central impression cylinder supports the substrate throughout the printing process, helping reduce the impact of material stretching and maintain stable color registration, especially when printing on flexible and extensible materials.

    Stable Color Registration

    The printing system provides registration accuracy of up to ±0.10 mm. Stable web tension, precision guiding and central impression support help maintain accurate color-to-color registration during continuous production.

    Constant-Temperature Central Impression Cylinder

    The central impression cylinder uses a constant-temperature water cooling system to help maintain stable printing conditions during continuous production. An industrial chiller can be added according to production requirements.

    Stable Web Tension Control

    The tension control system helps maintain stable web movement during unwinding, printing and rewinding. This supports consistent printing quality across different substrates and production conditions.

    Anti-Wrinkle Web Guiding

    Curved rollers before the printing units help spread and guide the web, reducing wrinkles and supporting stable material feeding before printing.

    Automatic Printing Pressure Control

    The printing system supports automatic pressure adjustment and pressure compensation during speed changes. This helps maintain stable printing pressure throughout the production process.

    Pre-Registration Function

    The pre-registration function helps bring the printing units closer to the required register position before production starts, reducing setup time and material waste during machine startup.

    Heavy-Duty Printing Frame

    The heavy-duty cast iron printing frame provides rigid support for the printing units and helps reduce vibration during high-speed operation, supporting stable printing quality.

    Heating and Drying Unit

    The heating and drying unit uses electric heating with intelligent temperature control. Independent air supply and exhaust fans help maintain stable airflow, while double-sided hot air drying and post-printing cooling support efficient drying during continuous production.

    Video Inspection System

    The video inspection system allows operators to monitor printing quality on screen. The inspection area can be adjusted according to the printing width, with fixed-point or automatic inspection functions.

    How It Works

    From Unwinding to Rewinding

    01.Unwinding

    The substrate is smoothly unwound and continuously fed into the printing line for stable production.

    02. Web Guiding

    The web guiding system keeps the substrate accurately aligned and reduces lateral deviation during operation.

    03. EPC Web Guiding

    The EPC system automatically detects and corrects web position to maintain precise alignment before printing.

    04. Tension Control

    The tension control system maintains stable web tension to reduce wrinkles, stretching, and registration errors.

    05. Central Impression Flexo Printing

    The central impression cylinder supports the substrate through each printing unit, helping maintain stable web movement and accurate multi-color registration.

    06. Heating & Drying Unit

    The heating and drying system quickly removes moisture or solvents from the printed ink to ensure consistent print quality.

    07. Cooling

    The cooling section reduces the web temperature after drying, helping stabilize the printed material before rewinding.

    08. Rewinding

    The finished web is smoothly rewound into uniform rolls for convenient handling, storage, and further processing.

    The substrate is smoothly unwound and guided through the printing line under precise tension control. The central impression cylinder provides continuous support as the web passes through each flexographic printing unit, helping maintain stable web movement, accurate color registration, and consistent print quality. After printing, the web passes through controlled heating and drying, followed by cooling to stabilize the printed material before it is smoothly rewound into finished rolls.
