Tresu is to introduce a new fast-change inking system for narrow-web flexo up to 800mm wide, the FlexiPrint Reservoir SaveInk chamber doctor blade, which should help cut down job changeover times. It’s suitable for use with both UV and water-based inks.
The chamber can hold 250ml – 2000ml of ink and more ink can be added manually if needed without stopping the press. It is completely sealed to prevent leaks and maintain pressure for foam-free printing and an even ink coverage across the web regardless of print speed.
Since the chamber can be sealed, the unit can be removed and remaining ink can be reused later. The chambers can be installed or removed safely in five seconds without the risk of spilling ink. It has a simple mounting process – the operator locks it to the anilox roll, and rotates it from a six-o’clock to a nine-o’clock position.
The doctor blades are in a pre-set position that ensures optimal anilox contact with minimal wear. There’s no need for further adjustment and an automatic indicator shows when the blades need to be replaced.
The system can work without a pump, though there is an optional pump available which gives more precise flow control, as well as the ability to return unused ink to the bucket. The pump system also allows for complete flushing and anilox cleaning for colour changes.
Henrik Kristensen, vice president of Tresu Ancillary, comments: “With shorter runs and faster turnarounds, label converters are under increased competitive pressure to eliminate waste. Tresu’s single-component SaveInk system makes an attractive option for an efficient label printing workflow, with its fast setup times, minimal maintenance requirements and capability for consistent quality at high speed. With a short return on investment, the benefits of our chamber doctor blades are a viable and value-adding alternative to investing in a new press.”
