Denmark-based Tresu has introduced its new FlexiPrint Reservoir SAVEink Chamber Doctor Blade – a light, fast-change inking system for narrow-web UV and water-based flexo applications that can be used without an ink pump. Chambers are air-tight and prevent leakage because of the OEM’s patented seals, and can be installed or removed safely in five seconds without the risk of spilling ink. To introduce the unit to its mounting, the operator locks it to the anilox roll, and rotates it from a six-o’clock to a nine-o’clock position. Removal reverses the process. Doctor blades are in a pre-set position, and there’s no need for further adjustments. The pre-set position ensures optimal anilox contact with minimal wear. An automatic indicator shows when blade replacement is necessary, so time isn’t wasted on unnecessary checks.
The chamber can hold 250 ml – 2,000 ml of ink, making it ideal for application of normal and spot colours, as well as high-ink transfer printing. Ink may be added manually without stopping the press, giving the system flexibility for long-run and short-run production. Since the chambers are sealed, there’s no risk of ink contamination and optimal pressure is maintained to ensure foam-free printing and even ink coverage across the web. The chamber maintains precise inking even at the high speeds demanded by narrow-web printers, said the copmany. Available in widths up to 800 mm, it can be fitted to almost any narrow-web press. For those using manual filling, the chambers can be removed and sealed so that the ink can be reused. As the unit features a single compartment, manual cleaning is fast and easy. Printers using an optional pump system have the advantage of precise flow control, as well as the ability to return any unused ink to the bucket. Complete flushing and anilox cleaning to enable colour changes is also possible with pump systems.
“With shorter runs and faster turnarounds, label converters are under increased competitive pressure to eliminate waste,” said Henrik Kristensen, Vice President of Tresu Ancillary. “Tresu’s single-component SAVEink system makes an attractive option for an efficient label-printing workflow, with its fast set-up times, minimal maintenance requirements and capability for consistent quality at high speeds. 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.”
