A new closed chamber doctor blade system launched by Danish flexo press and printing ancillary product manufacturer Tresu Group is designed to be lean, splash-free and to provide long ink-life for narrow-web water- and UV-flexo presses, the company says.
As well as requiring no ink pump and facilitating fast, tool-free colour- and blade exchange, the FlexiPrint Reservoir Chamber Doctor Blade ensures uniform ink coverage on the anilox roll, boosting yields even when volume requirements are as low as 0.2 litres.
With no moving parts, the lightweight, cassette-format system is situated at right angles to the anilox roll, with point-of-contact either in the three o’clock or nine o’clock positions, enabling even ink transfer without suction.
Fast, effortless changeover is possible by sliding and locking the chamber with ease into any position in the printing sequence of the press.
Reservoir levels are topped up manually, and human eye judgment is enough to determine when to replenish the reservoir. Alternatively, a float with a sensor can indicate when more ink is needed.
The system also features Tresu’s E-Line doctor-blade changing system for safe blade change in less than one minute.
“The FlexiPrint Reservoir system provides a clean method of ink transfer, ideal for maintaining maximum productivity, without compromising quality standards,” commented Henrik Kristensen, Tresu Ancillary sales manager.
Tresu Group has partnerships with several of the world’s leading flexo and offset OEM (Original Equipment Manufacturers), developing a wide range of auxiliary products for narrow, mid- and wide-web printing and coating situations.
