Product Description
Product Overview: The All-Servo Solution for Film & Labels
The NJZ-420B is a state-of-the-art Full Servo Flexo Printing Machine designed for versatility and precision. With a wider printing width of 420mm, this machine bridges the gap between narrow-web label printing and mid-web flexible packaging. Powered by an independent servo motor for each print station (Petal-type structure), it delivers exceptional registration accuracy, making it the perfect choice for printing on difficult substrates like BOPP, PET, PVC shrink films, and Thermal Paper.
Key Features & Technical Highlights
- Independent Servo Drive System: Each printing unit is driven by its own servo motor. This eliminates gear marks and vibration, ensuring perfect color registration (±0.1mm) even on stretchable film materials.
- Short Web Path Design: The optimized machine layout significantly shortens the distance from unwinding to rewinding. This minimizes material waste during startup and job changes, saving you money on expensive substrates like foil and film.
- High-Speed Production: Capable of running at speeds up to 150 meters/minute, ensuring high output for large-volume orders of bottle labels or ATM paper rolls.
- Versatile Ink & Drying: Compatible with both Water-based inks (eco-friendly) and UV inks. The machine supports customized drying combinations (Hot Air / UV Curing) to suit different materials.
- Integrated Finishing: This "All-in-One" solution can handle Feeding, Printing, Varnishing, Drying, Laminating, Die-Cutting, and Rewinding in a single pass.
Optimized Applications
The NJZ-420B excels in handling diverse materials from 20g to 250g:
- Unsupported Films: BOPP, PET, PVC, PE films (wrappers, shrink sleeves).
- Self-Adhesive Labels: Top-grade stickers for food, beverage, and cosmetics.
- Specialty Paper: Thermal paper (ATM rolls), Kraft paper, and Clothing tags.

FAQ: NJZ-420B Full Servo Flexo Printing Machine (Film & Label)
Yes, it is designed for this. Unlike basic gear-driven machines, the NJZ-420B uses Full Servo Technology to precisely control the tension of the material. This prevents "stretching" or distortion when printing on thin, unsupported films like BOPP wrappers or PVC shrink sleeves.
Traditional machines use a main shaft and gears to drive all stations, which can cause mechanical vibration and "gear marks" on the print. The NJZ-420B assigns a dedicated servo motor to each color station. This ensures ultra-smooth operation, higher precision (Registration ±0.1mm), and allows for faster setup times.
The NJZ-420B offers a maximum printing width of 420mm (Web width 430mm) and a top mechanical speed of 150 meters per minute. This makes it highly efficient for both medium-run label jobs and longer-run flexible packaging orders.
