Fast, lean flexo printing lines for paper and corrugated preprint

TRESU Solutions introduces a flexo printing line for high-end corrugated preprint applications that offers reduced waste, short setup times, consistent colour quality and production speeds of up to 600m/min.

The new 1700mm-wide sleeve-based concept, featuring between seven and 11 colour stations, offers a lean, productive and ergonomic alternative that limits downtime when shorter runs are required and meets the need for stricter colour targets, and accurate linework reproduction, demanded by brand manufacturers. 

Automation, simple logistics and easy handling are central qualities of the printing line. Fast anilox and sleeve change is possible within 10 minutes. Furthermore, printing units that are idle during a production run can be prepared for the next job while others are running, without affecting stability. Automatic press controls ensure registration and colour targets are achieved with minimal material waste in the start-up phase. The press also comes with a robotically managed sleeve-storage system, positioned nearby.

TRESU’s ancillary equipment provides fully controlled ink logistics on each flexo station, regulating ink flow throughout the production run in an enclosed environment from bucket to printing sleeve. Benefits include optimised drying efficiency, higher reflective and gloss values, automatic cleaning and ink changes in minutes without manual intervention. Key equipment includes:

• Carbon-fibre chamber doctor blade systems with patented seals, preventing leakage and providing corrosion-resistance

• TRESU F10 iCon ink supply system, regulating flow and providing automatic, fast chamber cleaning 

• Clamping systems for fast, safe doctor blade exchange
