4-Color Gear-Driven Stack-Type Printing Press（TF-G04-1000 1200）

Product Overview

The TF-G04-1000 1200 is a high-performance 4-color stack-type full servo flexographic press integrated with Siemens technology, designed to meet the demanding requirements of modern printing production. With a maximum material width of 1200mm and an industry-leading ±0.05mm registration accuracy, it delivers exceptional printing quality across a vast range of substrates, including plastic films, various papers, aluminum foils, composite films, and non-woven fabrics. Built on advanced stack-type flexographic technology, it incorporates 4 independent printing units, each driven by international-brand servo motors, ensuring precise multi-color registration and consistent ink transfer. Its intelligent centralized control system and versatile configuration make it an ideal solution for diverse, multi-variety production environments, supporting both high-volume continuous production and frequent job changes with minimal downtime.

Technical Principles & Core Components

This press operates based on advanced stack-type flexographic technology, where 4 independent printing units are stacked sequentially to achieve high-precision multi-color registration. Each unit is equipped with independent servo motors that drive the plate and impression cylinders separately, enabling precise control over printing pressure and registration. A closed-chamber doctor blade system works in conjunction with precision ceramic anilox rollers to ensure uniform ink transfer to photopolymer plates, resulting in clear, sharp prints on various substrates. The entire system is centrally managed by a Siemens PLC, which integrates high-precision photoelectric encoders for closed-loop tension and registration control. This closed-loop feedback mechanism continuously adjusts parameters during production, maintaining consistent quality even at high speeds. The press also features a dual-stage electric heating drying system, combining main oven and inter-color drying configurations to ensure thorough ink drying, eliminating issues like ink offsetting or buildup during high-speed operation.
