This unit has been developed from the very
successful and well proven T162 Rotex plate printing down unit used in
the graphic arts over many year's. It consists of a robust metal cabinet
that splits into two for ease of installation where access is limited.
The lower section contains the light source, power pack and suction pump,
whilst the upper cabinet has the control box fitted onto the front face
with the glass and blanket frame mounted on the top.
The blanket frame is pivoted at the rear and is held open by gas dampers.
Air is drawn out through a series of holes around the inner face of the
frame so allowing the flexible rubber sheet to be pulled down over the
screen frame quickly and efficiently.
There are 3 versions available, for each of the 2 sizes of machine.
The basic unit is fitted with a timer
with which to control the exposure, and no shutter, so the lamp will strike
to carry out the exposure, and then shut off, this unit is adequate where
a small number of screens per day are required, less than 30.
For more accurate control of the exposures,
an integrator model is available, but still using the same lamp unit,
with no shutter, so for lower production enviroments, but with more accurate
control of exposure.
For higher production environments, where a larger number of screens are
produced, or one exposure, following immediately after the other is required,
then a shuttered light source is used, along with an integrator to control
the exposure time
Integrator models have 8 user selectable
All the machines use a 2kW light source.
A 4kW version is available for slower resists.
