The Four Color Rotogravure Printing Machine is a continuous roll to roll printing system designed for flexible film materials. The machine structure integrates unwinding, multiple printing units, drying modules, and rewinding into one production line. Materials are guided through several printing cylinders while operators monitor the process from the front operation area and upper platform. The machine frame provides a clear material path and centralized control cabinet for production management. The synchronized mechanical transmission ensures stable rotation of rollers and printing cylinders during operation. This layout allows operators to observe the material movement, printing status, and machine running condition clearly during continuous industrial production.

High Speed

The printing system supports continuous roll processing with a maximum production speed of 250 meters per minute depending on model configuration. This speed capability allows large film rolls to be printed within shorter production cycles. The mechanical shaft transmission maintains synchronized rotation between rollers and printing cylinders so that the material transport remains stable during high speed operation. Even when processing wide film materials up to 2500 millimeters, the system can maintain steady movement across the printing units. Stable speed performance ensures that large production batches can be processed efficiently while maintaining consistent printing contact and machine stability during long industrial printing runs.

Accurate Register

The machine maintains stable color alignment across four printing units through precise cylinder synchronization and controlled film transport. The technical data shows that the printing registration accuracy can reach within plus or minus 0.1 millimeters during operation. This accuracy ensures that each printed layer aligns consistently across the material surface. Stable registration control is maintained even when operating at high speeds and processing long film rolls. Maintaining this alignment accuracy is essential for continuous production because small deviations can affect the final print quality across large roll lengths. The mechanical transmission system ensures synchronized movement of cylinders to maintain this precise registration tolerance during printing.

Wide Materials

The equipment supports a wide range of flexible materials including PE, OPP, BOPP, CPP, PET, PVC, NY, paper, and nonwoven materials. These substrates differ in structure and surface characteristics but can be processed by the same printing system. The machine supports material widths from 1300 millimeters to 2500 millimeters, allowing both medium and large roll materials to be processed. The roller guidance system keeps the film moving smoothly across the printing cylinders so that printing pressure remains uniform across the full width of the material. This wide material compatibility allows the machine to handle different flexible substrates used in film processing industries.

Stable Tension

Stable tension control is maintained across the unwinding, printing, and rewinding sections to keep the film surface flat during processing. The machine supports maximum unwinding and rewinding diameters up to 1000 millimeters, allowing large roll materials to be processed continuously. Maintaining uniform tension across large roll diameters ensures that the film remains aligned when passing through the printing cylinders and drying sections. The coordinated roller control helps prevent material deformation or instability during printing. Stable tension control supports continuous operation across long production cycles where large film rolls are processed without interruption.

Cylinder Range

The printing system supports a flexible range of cylinder sizes with printing cylinder diameters from 120 millimeters to 300 millimeters. This cylinder range allows different print repeat lengths to be used depending on production requirements. The cylinder mounting structure ensures stable installation and accurate alignment during operation. When combined with the maximum printing speed of 250 meters per minute, this cylinder range allows consistent printing performance across different production configurations. The synchronized cylinder movement ensures that the film transport remains stable while maintaining correct printing contact during continuous operation.

Diaper Film

Disposable diaper manufacturing requires printed breathable film layers before the materials are integrated into multilayer product structures. These films are processed in large roll formats before entering automated diaper assembly lines. The printing machine supports wide roll materials up to 2500 millimeters, which matches the film dimensions used in high capacity diaper production lines. Continuous roll printing ensures that large material batches can be processed efficiently before downstream converting processes.

Adult Pads

Adult incontinence product production uses breathable films that are printed before they are cut and assembled into finished products. These film rolls are often processed in long lengths to support continuous manufacturing operations. With production speeds reaching 250 meters per minute, the printing system can handle large roll materials efficiently. Continuous printing ensures that film materials remain consistent across the entire roll before they are transferred to converting equipment used in adult hygiene product manufacturing.

Sanitary Pads

Sanitary napkin production lines require printed film layers that are later incorporated into multilayer product structures. The rotogravure printing system processes these materials in continuous roll form so that the films can be directly fed into converting equipment. With registration accuracy reaching within plus or minus 0.1 millimeters, printed patterns remain aligned across long film rolls used in sanitary product manufacturing. This ensures consistent printed graphics during large scale production.

Pet Pads

Pet absorbent pads use printed film layers as protective surfaces before final product forming. These materials are processed in roll form before they are cut into individual pad structures. The machine supports large roll diameters up to 1000 millimeters, allowing extended production runs without frequent roll replacement. Continuous roll printing ensures stable material supply for pet hygiene product manufacturing lines.

Hygiene Sheets

Disposable hygiene sheets use printed film layers that are processed before downstream assembly. The printing machine processes these materials in continuous roll form so that large batches can be printed efficiently. With production speeds up to 250 meters per minute, long film rolls used in hygiene sheet manufacturing can be processed within industrial production timeframes. Stable roll transport ensures uniform printed results across the entire material roll.

Mattress Pads

Mattress protection products require printed breathable films that are integrated into absorbent product structures. These materials are processed in large roll formats before they are laminated or assembled into final products. With roll diameter capacity reaching 1000 millimeters, the machine can support continuous production cycles in mattress pad manufacturing facilities. This allows large quantities of film materials to be printed before downstream processing.

Packaging Film

Flexible packaging films such as BOPP, PET, CPP, and paper materials are printed before slitting and converting processes. The rotogravure printing machine processes these materials in continuous roll form while maintaining stable material alignment across the printing units. With supported material widths up to 2500 millimeters, the machine can handle wide packaging films used in industrial packaging production lines. Continuous roll printing ensures consistent graphics across large packaging film batches before conversion into finished packaging products.
