Truly "cool" UV through mirror
quartz technology
The Ultrapak® arc lamp offers the option of true "cool"
UV curing of inks and coatings on heat-sensitive materials
for almost all makes of narrow web presses, including
Gallus, Aquaflex, Webtron, Mark Andy, Nilpeter, and Didde.
The Ultrapak® system
utilizes an optional dichroic reflector and quartz IR filter
in combination with superior heat-management features to permit
efficient curing of inks or coatings without the use of chill
rolls.
The Ultrapak® system uses a unique 0.75" (19 mm)-diameter
bulb on its 400 W/in (160 W/cm) mercury lamp system for a
more focused exposure area and efficient cure. Measured against
equivalent 600 W/in (240 W/cm) lamp systems with traditional
1.1" (28 mm)-diameter bulbs, an increased cure speed
of up to 33 percent can be achieved, running, for example,
a 7-10-micron black screen ink. Gallium or metal additive lamps
are also available to provide the most efficient spectral
output for certain UV processes and heavy ink laydowns.
The Ultrapak® UV curing system provides outstanding performance
and customer interface features. The system design allows
ganging of lamp systems to enable rapid reconfiguration and
installation on multiple-lamp presses. Interface with the
operator and with the press is made through PLC-based controls
and an operator display/keypad or optional multi-lamp monitoring
touch-screen.
The modular cassette design is fully interchangeable from
print station to print station, providing the flexibility
to cure at different locations throughout the press. The Ultrapak®can
be supplied with new in-line presses through the OEM or as
a retrofit on existing machines to allow partial or full UV
capability.
