Tresu announces the introduction of its 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, thanks
to Tresu’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
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, so time is not wasted on unnecessary checks.
The chamber can hold 250ml – 2000ml 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 and short-run production.
Since the chambers are sealed, there is no risk of
ink contamination and optimal pressure is maintained, to ensure 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. Available in
widths up to 800mm, the Tresu FlexiPrint Reservoir SaveInk chamber may be
fitted to almost any narrow web press.
For those using manual filling, the chambers can be
removed and sealed so that 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 unused ink
to the bucket. Complete flushing and anilox cleaning to enable colour changes
is also possible with pump systems.
Henrik Kristensen, vice president, 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.”
