Tresu – New SAVEink chamber doctor blade
DENMARK • Tresu introduces its FlexiPrint Reservoir SAVEink chamber doctor blade. The light, fast-change inking system for narrow-web UV and water-based flexo applications can be used without an ink pump.
According to Tresu, the chambers are air-tight and prevent leakage 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 is no need for further adjustment. The pre-set position ensures optimal anilox contact with minimal wear. An automatic indicator shows when blade replacement is necessary. The chamber can hold 250 ml – 2000 ml of ink and is suitable for application of normal and spot colours, and high ink transfer printing. Ink may be added manually without stopping the press. According to Tresu, since the chambers are sealed, there is no risk of ink contamination and optimal pressure is maintained. The chamber maintains precise inking and is available in widths up to 800 mm. For those using manual filling, the chambers can be removed and sealed so that ink can be reused.
Printers using an optional pump system have the advantage of precise flow control, as well as the ability to return unused ink to the bucket. Complete flushing and anilox cleaning to enable colour changes is also possible with pump systems.
