the crate.
2. Aer the top is removed, remove the front panel of
the crate. The front panel is the side opposite of the
vacuum motor.
3. With two people li the exposing unit and
place it into the desired locaon. Remove all of
the plasc wrap and foam packing. When the
blanket of the Lumitron is opened there will be a
small cord on the glass, do not throw it away.
Plug the unit into a grounded wall outlet.
Congratulaons! The Lumitron UV is now ready
to use.
Exposing a Screen
3730 E. Southern Avenue, Phoenix, AZ 85040 USA
800-778-8779 Workhorseproducts.com 6
There are many variables that inuence how a screen is to be exposed. Some of these variables are: emulsion
brand, emulsion type, coang technique, mesh count, humidity, atmospheric temperature, and even the
light source itself. Therefore, there is no denive procedure to properly expose a screen.
Step 1:
Properly prepare the screen to be exposed. The screen needs to be
clean, dry and properly tensioned.
Step 2:
Direct emulsion should be applied with a scoop coater, which is
available in a variety of sizes. The scoop coater should be able to t
just inside the screen and be slightly larger then the image. It’s best
to use a sharp edge scoop coater, because the sharp edge pushes a
thin deposit of emulsion making it possible for ne details to be
printed.
Working under subdued light, ll the coater’s reservoir with room
temperature direct emulsion. Put the screen in the vercal posion
with the print side facing out. Place the coater at the boom edge
and lt it slight forward unl the emulsions touches the mesh. With
even speed slowly pull the coater towards the top of the screen.
Stop pulling the coater about two inches from the top and lt the
coater slightly backwards to let the emulsion sele into the reser-
voir. Repeat this process for the inside squeegee side.
It’s important to coat the outside print side rst because it will leave a heavier deposit emulsion on the
outside of the screen, which is needed.
Most likely, a small amount of emulsion will escape from the reservoir during the coang process and leave
thick deposits along the edge of emulsion. Just simple remove the thick deposits with a scraper.

Step 3:
The screen needs to be dried in a dark locaon. Dry the
screen in a horizontal posion with the outside print side
facing down. This posioning is essenal to aid the
drawing emulsion to create a at and smooth surface. A
fan can be used to circulate the air around the screen
decrease the drying me. The normal drying me for a
properly coated screen can be anywhere from 30 –60
minutes. However, areas that have moisture in the air
will take exceedingly longer.
Step 4:
There is no standard exposure me because of all of the variables
involved. Use an exposure calculator to properly determine the
correct exposure me. Most emulsion manufactures have their
own exposure calculator, but they all relavely funcon in the
same manner.
Exposure calculators are lm posives that have various degrees
of detailed lines that are covered with dierent factors. The
purpose is to expose the calculator onto a screen as a starng me and
each lter will have a factor number. Aer the screen is washed out,
observe which image is the hardest while containing the most detail
and mulply the factory number by the starng exposure me to get
the correct exposure me.
A Workhorse SD-10 drying cabinet will immensely speed up the drying process and eliminate the danger of
dust, which will guarantee high quality screens and increase producon speed.
For example, a screen is exposed for one minute with the calculator and the best image washed
out has a lter factor of .5 , so 1:00 x .5 = 30 seconds. To guarantee the best screens test every screen that
has a dierent variable like: dierent mesh count, dierent emulsion brand, and dierent coang technique.
A duel cure emulsion will need a starng point of at least two minutes with an exposing calculator.
A basic diazo emulsion will need a starng point of at least ve minutes with an exposing calculator.
It’s best to test for each season change. The seasons inuence temperature, humidity and moisture that will
aect the exposing of a screen.

Step 5:
Release the red latch and li the hold down blanket to
expose the glass. Inspect the glass to make sure that it’s
clean. Clean glass makes a beer quality screen.
Step 6:
Aach the lm posive to the print side. The posive
should be posion so that from the squeegee side,
the posive is read le to right. It’s very helpful to
use a preregistraon system to make sure each piece
of lm is aached to the screen in proper relaon to
the other images.
Step 7:
Lay the frame on the glass with the lm side down
and the squeegee side up. Next, lay the rope from
inside the screen across the screen edges and in
front of the vacuum hole. The rope creates an escape
route for the air inside the frame, it also keeps the
vacuum port from sealing against the glass.
Step 8:
Close the vacuum lid and latch it into place with the
red latch/seal mechanism. Turn the power buon on,
which will power the mer and start the vacuum.
Eventually, the hold down blanket will encompass
the screen and the vacuum motor will change pitch
as it enters idle phase. Set the exposure buon and
press the start buon. Once the mer reaches zero
an alarm will ring signifying the exposure process is
over.

Step 9:
When the exposure me ends turn the vacuum
switch to the o posion. Release the latch handle
and very slowly li the lid to release the air. Opening
the lid slowly is very crical, because the screen
could potenally be pressurized to the top of the lid
and if lied too quickly it could fall and break the
glass.
Next, take the screen to be washed out in a sink to be
developed.

The backside of the Lumitron is equipped with two
electrical outlets. One outlet is used to power the
vacuum motor, and the other outlet is a spare. The
outlet is 6 amps maximum.
Electrical Outlets
Cleaning the Glass
Disconnect the power before servicing the Lumitron.
Use a screw driver to pry up the glass top. Carefully
pivot the glass upward and place it on a so and clean
surface. Clean the glass with high quality cleaner, do
not use cleaning solvents or chemicals.
Replacing the Bulbs
Disconnect the power before servicing the Lumitron.
To remove the uorescent bulbs rotate the 1/4 turn
and remove the bulb from the holder. Replace the
bulbs by inserng the pins in the bulb holder, and
then rotate the bulbs to lock in place.
Replace all of the bulbs all at the same me. This will
ensure the exposure level remains consistent across
the enre exposure surface. Place the glass back onto
the Lumitron by inserng the back of the glass into
the rear of the track and slowly lower the glass into
posion.

Replacing the Blanket
1. Close the lid and latch it. Remove the vacuum hose
from the vacuum port (A). Insert a small screw driver
into the top of the gas shock (B) and pry o the spring
loaded cap to remove the gas shock.
Unbolt the hinges from the rear of the Lumitron (C).
Unlatch the top to remove the top frame and vacuum
blanket assembly.

2. Remove all of the screws from the blanket retaining
the bracket. Remove the frame to replace the
damaged blanket.
Posion the replacement blanket over the frame
allowing it to droop naturally. The blanket should not
be stretched ght. Replace the blanket retaining
bracket with the screws that were removed earlier.
Replace the frame and blanket assembly onto the
Lumitron base, then align and reaach the hinges.
3. Reaach the gas shocks by pushing the top of the
gas shock connector onto the pivot ball and connect
the spring loaded cap.
Check for leaks before returning to normal operaon.
