Stack Flexo Printing Technology

Stable Double-Sided Printing Solutions for Diverse Packaging Materials

Changhong Stack Flexo Printing Machines are designed for high-speed, stable printing on plastic films, paper, nonwoven fabrics, and PP woven materials. The machine supports double-sided printing with accurate color registration, while its heavy-duty frame, intelligent tension control, imported ceramic anilox rollers, and precision guide rollers ensure consistent print quality and reliable production performance.

CHANGHONG Key Features

Double Sided printing

The stack-type structure supports Double sided printing, allowing the machine to handle different multi-color packaging requirements within one production process.

Precise Color Registration

The printing system provides registration accuracy of up to ±0.15 mm. Precision guide rollers and stable web tension help maintain accurate color-to-color registration during continuous production.

Precision Printing System

Imported ceramic anilox rollers provide consistent ink transfer, while high-precision guide rollers help maintain accurate web positioning and stable printing quality.

Intelligent Tension Control

The tension control system helps maintain stable web tension during unwinding, printing and rewinding, supporting consistent printing quality across different substrates.

Heavy-Duty Machine Frame

The reinforced machine frame provides stable support during high-speed printing and helps reduce vibration and web deviation during continuous production.

Reduced Ghosting and Misalignment

Stable printing pressure, precision guide rollers and controlled web tension help reduce pattern ghosting, color misalignment and other common printing defects.

Convenient Job Changeover

The open printing structure provides easy access to the printing units, making plate and anilox roller replacement more convenient and helping reduce setup time between jobs.

Environmental Ink Options

The machine can be configured for water-based ink printing on suitable paper and nonwoven applications. The corresponding drying and ink supply systems can be selected according to the substrate and production requirements.

How It Works

From Unwinding to Rewinding

01. Unwinding

The substrate is smoothly fed into the machine through the unwinding system, providing a continuous and stable material supply.

02. Web Guiding

The automatic web guiding system keeps the material accurately aligned, reducing web deviation during high-speed operation.

03. Tension Control

The intelligent tension control system maintains consistent web tension to prevent wrinkles, stretching, and printing errors.

04. Double-Sided Printing

The printing units apply colors through anilox rollers and plate cylinders, enabling accurate double-sided printing with stable registration.

05. Drying

The drying system quickly removes moisture or solvents from the ink, ensuring clear and consistent printing results.

06. Cooling

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

07. Rewinding

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

The substrate is smoothly unwound and guided through each printing unit under precise tension control. Ink is transferred through the anilox roller and plate cylinder to create accurate, consistent prints before the web passes through drying, cooling, and final rewinding.
