TRESU of Denmark introduced its FlexiPrint Reservoir SAVEink chamber doctor blade, described as a light, fast-change inking system for narrow-web UV and water-based flexo applications that can be used without an ink pump.
TRESU explains the chambers are air-tight and prevent leakage based on patented seals, while they 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.
The doctor blades are in a pre-set position, explains TRESU, and there is no need for further adjustment. The pre-set position provides optimal anilox contact with minimal wear. An automatic indicator shows when blade replacement is necessary, so time is not wasted on unnecessary checks.
The chamber can hold 250 ml to 2,000 ml of ink making it suitable for the 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 and short-run production.
Since the chambers are sealed, TRESU explains there is no risk of ink contamination and optimal pressure is maintained, to provide foam-free printing and an even ink coverage across the web.
The chamber maintains precise inking even at the high speeds demanded by narrow-web printers, explains the company. Available in widths up to 800mm, the TRESU FlexiPrint Reservoir SAVEink chamber may be fitted to almost any narrow web press.
