SET UP
1.0 THE RIGHT ALCOHOL/WATER
MIXTURE
The WetScore uses a mixture of Isopropyl ALcohol
(Commonly known as Rubbing Alcohol) and water. The
alcohol serves two purposes. First, it acts as a drying agent
to cause rapid evaporation of the solution from the signa-
tures. Secondly, it insures that the fluid maintains a uniform
line upon the stock. For these reasons it is important that
the solution be mixed in the proper proportions. Too little
alcohol in the solution and the fluid will tend to spread out
upon the sheets in a ribbon rather than a fine line and the
signatures will feel excessively wet. Too much alcohol and
the fluid will have a difficult time absorbing into the stock
and inconsistent folds will result.
As a rule of thumb, during operation of the WetScore
the signatures should feel wet to the touch immediately after
folding and dry within 3 to 5 minutes. You should be able to
smell the alcohol on the signatures. The folded signatures
should appear flat. If the signatures appear to be rippled
along the scored and folded edge you are using too much
water and we advise remixing your solution. To avoid
unwanted downtime, we advise keeping a premixed container
of solution nearby the folder to fill the water bottle during
operation of the WetScore.
2.0 DETERMINE THE NUMBER OF
SCORES
In most cases you will want to use the WetScore when
you are folding in the 8 page (right angle). We recommend
using the WetScore not only for those situations in which
you would normally use a mechanical score, but for folding
with perforators as well. The WetScore is not meant to
replace the perforators, but operates in addition to them.
The resulting signatures will be flatter, usually eliminating
dog-ears and assuring you straight perforations.
3.0 BLEEDING AIR FROM THE TUBING
The Greatest factor in insuring a strong flow
of fluid through the WetScore is the asbence of
air in the tubing that runs from the bottle to the
control valves.
A. BLEEDING THE TUBING FROM THE
ON/OFF SOLENOID TO THE CONTROL
VALVES
1. Plug the WetScore into a 110V. outlet.
2. Make sure that the LED indicator light on the
photoelectronic sensor is not lit,indicating that
the solenoid is closed.
3. Close all of the control valves.
4. Remove the rubber cap from the end port of
the control valves.
5. Place a rag over the open port to catch fluid
when the solenoid is opened.
6. Place your free hand under the sensor to
open the solenoid.
7. Allow fluid to run through the system until no
air is visible in the tubing between the solenoid
and the control valves.
8. Remove your hand from under the sensor,
when the flow of fluid stops, replace the cap
on the open port.
