The latest generation of Gallus machine systems incorporates cutting-edge control technology, offering label printers a standardized technology platform and operational concept. This ensures seamless integration and potential synergies for users employing various Gallus machine systems. Additionally, the press features an intuitive user interface based on a modern touchscreen panel, enhancing user guidance. Numerous hardware enhancements, including improvements to web transport and register accuracy, have been implemented based on feedback from Gallus RCS users, further optimizing performance. Moreover, the offset printing unit of the Gallus RCS 430 now boasts improved color stability thanks to optimized inking units.
Top-tier automation
The utilization of Flying Imprint for flexographic printing enables operators to modify texts and designs seamlessly without halting production. Moreover, the Gallus RCS 430/570 boasts optimal end-to-end automation, facilitating rapid job changeovers and setup times with minimal wastage. Its versatile format variability ensures complete flexibility in printing methods, substrates, and job configurations.
Offset printing process with the Gallus RCS 430
Automation
The Gallus RCS 430 features separately driven inking and wetting units, enabling the press to establish the required ink/water balance before commencing the actual printing process. During startup, the offset unit and format cassette rotate at setup speed, while the web moves at just 1 m/min, facilitating rapid attainment of printing quality with minimal startup waste. Combined with ink zone presetting, the Gallus RCS 430 establishes a new, cost-effective standard for label printers utilizing offset printing.
Leading Quality in UV Offset Printing
With the Gallus RCS 430, label printers can attain print results of the utmost quality while optimizing output and cost-effectiveness. Its sturdy construction, advanced servo drive technology, and intuitive user interface guarantee optimal print quality. Leveraging its high level of automation, the Gallus RCS 430 achieves offset printing outcomes comparable to sheetfed offset quality.
Exceptional Offset Inking and Wetting Unit
The Gallus RCS 430’s inking and wetting unit boasts 21 rollers, ensuring consistent, outstanding, and reproducible printing quality alongside minimal setup times and reduced waste. Following the model of modern sheetfed offset presses, the wetting solution is applied via a separate forme damping roller. Three inking rollers then transfer the ink to the plate cylinder. A bridge roller facilitates the connection or disconnection of the wetting unit from the inking unit, allowing for swift inking-up, washing, or printing without the wetting unit, such as varnishing solids. Separating the wetting and inking units is also recommended when working with metallic inks.
Consistently Reproducible Quality
With state-of-the-art configurable servo direct drives, the Gallus RCS 430 ensures uninterrupted production. The inking unit maintains a constant temperature, while the ink quantity adjusts continuously to the operating speed. Additionally, direct drives power the wetting unit’s fountain roller and doctor roller, enhancing precision and consistency. The motorized printing units offer swift and straightforward adjustments, guaranteeing consistent and accurate reproduction of print outcomes. Utilizing an independent drive controller for the doctor-roller drive allows customization, saving, and easy retrieval of ink/water profiles for each individual offset printing unit on the Gallus RCS 430. These profiles can be conveniently recalled later via the job data memory. Moreover, the assignment of relevant ink and water profiles is preserved for repeat jobs, as the data can be accessed from the main memory whenever needed.
