Technical Definition

A stack-type flexographic printing press is a multi-color printing device that uses vertically stacked independent printing units to achieve high-precision registration, based on advanced flexographic technology. It enables accurate ink transfer onto diverse substrates to meet high-quality packaging printing demands, serving as a core solution for flexible packaging production .

Main Classifications:
1. Full Servo Series: High-precision standard line, suitable for high-speed, high-accuracy printing needs, featuring independent servo-driven printing units and 260 m/min design speed .
2. Semi Servo Series: Cost-effective balanced line, ideal for medium-speed production with reliable registration accuracy, supporting 220 m/min design speed .
3. Gear-Driven Series: Entry-level stable line, designed for small-batch, low-speed printing scenarios with 120 m/min design speed .
4. Synchronous Belt-Driven Series: Mid-range efficient line, balancing speed and precision with 150 m/min design speed .

Our design centers on trust, precision, stability, and customization, with strict adherence to full-life-cycle reliability standards to deliver consistent, low-maintenance solutions for industrial scenarios .

Technical Principles & Core Architecture

The core working principle relies on flexographic technology with stacked independent printing units. Each unit uses a closed-chamber doctor blade system to ensure uniform ink transfer from ceramic anilox rollers to photopolymer plates, then onto substrates. A Siemens PLC centralizes control of tension and registration via high-precision photoelectric encoders .
Core Architecture Modules:
1. Independent Printing Units: Each unit is driven by international-brand servo motors, enabling precise adjustment of plate and impression cylinders for accurate multi-color registration .
2. Closed-Loop Tension Control System: Automatic detection and compensation from unwind to rewind prevent material stretching or slackening, eliminating registration deviations at high speeds .
3. Intelligent Centralized Control System: Large touchscreen manages operational parameters, stores job recipes, and tracks historical data to simplify production changeovers .

Compared to traditional gear-driven presses, our servo-driven series offers 2-3x higher production speed, ±0.05mm registration accuracy (reducing waste by 15%), and flexible customization options to meet diverse substrate and size requirements .
