RXP (optional lid) & X-Vactor Vacuum

Set-Up & Preparation: UV Exposure Unit: First, have a light safe room. Light safe, must be an area
sealed from UV rays. Place the unit on a at surface and plugged in. Separate the unit from the wash out
area, with space or a shower curtain to prevent over spray in a tight space.
Step 1. Prep For Exposure: Always clean the glass prior to exposing a screen. For lidless units, make
sure the foam, that came with the unit, is cut to t the inside of your frames, trim if needed.
RXP without lid: Cut a board to the size of the foam and place on top of the foam. Weigh down evenly
with four gallon containers (50-60 pounds). Set a timer and expose.
X-VACTOR: Connect the vacuum hose to nipple on blanket and tighten clamps. There are eight exposure
bulbs and two yellow safe lights (place on the far end of the unit), test bulbs before installing glass. For
possibly dirty, reclaimed frames, use muslin cloth to protect the vacuum blanket. Place the rope into the
frame along the edge. This allows the vacuum to pull all the air out, for full lm to screen contact.
Step 2. Film: The image on the lm must be 100 percent opaque (no light shines through positive area).
Hold your lms up to the light; there shouldn’t be any light seen through the image (black) area. If light
comes through, print another copy and stack them together or go over the lms with a lm opaque pen.
With laser printers, apply toner aid to enhance the darkness of the toner on the lm.
Step 3. Exposure Time: Unltered black light (HUV) exposure tables expose coated screens by
wavelength and strength of UV light. If you’re not using one of these light sources, check the step-wedge
instructions. After exposing the image on the screen will be viable prior to washing out. It’s recommend to
use a dual cure emulsion with these units. After taping the screen artwork, clean the glass and place the
screen on the units.
RXP without lid: Place foam pad inside screen frame. Set board on top of pad and add minimum 40
pounds weight to top. This creates positive contact between screen, lm and glass. Turn unit on. When
nished exposing, the unit will turn itself off. Take the positive off, remove any tape and store accordingly.
Wash out screen according to instructions provided.
X-VACTOR: Place one end of the rope along the inside of the frame. Check the blanket for tears (cause
suction loss). Close and lock the lid, and turn on the vacuum switch. After all the air has been removed
and the timer has been set, turn on the exposure switch.
Note: The switch activates the exposure then resets for the next exposure, to interrupt the exposure you
will need to unplug the unit. When the timer expires, turn off the vacuum, unlock the lid and remove
screen from the unit.
Step 4. Wash Out (use a light safe area): Gently wet both sides of the screen, and let sit for 30
seconds. Now spray the shirt side forcefully until image start to clear. Rinse both sides with a gentle spray
until no soft / slimy emulsion is left. Lay the screen down as if you were printing, lay a single sheet of
newspaper inside and BLOT excess water with newsprint quickly. DO not rub the inside as it is still soft. If
the newspaper sticks, simply wet again to remove, then repeat the process.

Step 5. Pin Holes, Block-Out & Touch-Up: While the screen is still slightly damp but not soaking
you can apply blockout with a plastic applicator to the shirt side. Apply thin to seal the screen edges and
possible pinholes, let dry completely before post hardening (re-exposing for strength).
Option 1: Use Red Coat Block out to cover the pin hole or areas needed. Let dry for
about 15 minutes or until completely dry to the touch. This is also an option on press when
breakdown occurs. Option 1 is preferred.
Option 2: Use a block out pen to cover the pin hole or areas needed. Let dry for about
15 minutes or until completely dry to the touch. This is also an option on press when
breakdown occurs.
Option 3: Use scotch tape or screen tape, to block out pin holes on the shirt side of the
screen, tape will pick up ink stains after wiping and transfer;
Step 6. Screen Taping: Apply solvent resistant tape on the outside and inside edges of the screen. This
will block ink from getting stuck in the corners of the screen or passing through to the substrate accidentally.
Troubleshooting: Screen Exposure Variables
Mesh
1. Mesh tension: Too low or too high. Higher tensioned screens will expose faster.
2. Mesh count / color: Higher mesh counts will expose slower. Dyed mesh will have a bit longer exposure
than a white mesh. Approximately 15-20 percent more.
Coating
1. Scoop coater size ratio to open mesh area: If the coaters edges are too close to the frame they will be
held up on the mesh due to the tension of the mesh as it approaches the frame. This results with more
emulsion deposited in the center of the screen from tension sagging.
2. Exact coating thickness: Multiple coats will increase the exposure time. The more layers of emulsion, the
longer it will have to expose for.
3. Scoop coater: The two sides deposit different amounts of emulsion per stroke. The more rounded side
will deposit more emulsion per pass requiring a longer exposure time.
4. Speed of stroke: A slower stroke will deposit more emulsion.
Emulsion
1. Sensitize: Pre-sensitized emulsions expose faster than diazo emulsion.
2. Solids content: Higher solid content emulsions penetrate screen mesh better and give edge denition.
3. Age: Expired emulsions have erratic results, always check expiration before use. Pre-sensitized emulsions
generally have a one year shelf life. Diazo emulsions have a 4-6 week window of use after mixing.
4. Moisture in emulsion layer: Humidity is key, using a dehumidier is best practice. The humidity level
should be between 30-40 percent. Emulsions that aren’t completely dry can bubble and peel away from
the screen in the wash out. It’s recommended, to dry screens in a humidity controlled area for 6 hours
(minimum) prior to exposing.
Exposure unit
1. Bulb type: Exposure times vary whether you are using a 500W bulb up to a metal halide unit.
2. Bulb age: Over time and have less UV output. Exposure times lengthen with bulb age.
3. Lamp distance to stencil: The closer the screen is to the bulbs, the faster the exposure will be.
Not all of the image washes out
1. Over exposed: Check the lm for opacity. If they aren’t opaque enough light will pass through, reduce
the exposure time. Use an exposure calculator or step wedge test to determine the correct time.
2. If you are using an open face exposure unit make sure you are using the correct amount of weight,
evenly distributed over the image. Uneven pressure causes a poor and uneven exposed screen.
3
Too much of the image washes out
1. The screen is under exposed, increase the time. Use a step wedge test or exposure calculator to
determine correct time. Plus, check the bulbs, they will weaken over time and will need replaced.
2. Ensure you are using the correct mesh count for the amount of detail required. If your image has
halftones choose your screen count by multiplying the halftone line count (LPI) by 5. Example: 35 LPI x
5 = 175 mesh 45 LPI x 5 = 225 mesh 55 LPI x 5 = 275 mesh.
Step-Wedge Test – Used to determine exposure times: If you’re unsure
of an exposure time perform a “Step-Wedge” test, by dividing the screen into
four sections and marking each with a specic exposure time, then increasing
in increments of two minutes per section.
Mark the screen and at the top of each section write 4 minutes, 6, 8 and 10.
Produce a piece of art with type, shapes and even some halftones and place
it in the 4 minute section, cover the remaining three sections with the black
sheet; expose for 4 minutes.
After the rst exposure, move your art and sheet to the next section, covering
the 4 minute section with a light safe sheet as well. Expose only this section
for 6 minutes and follow this procedure until ALL four sections have been
exposed at the times indicated. Wash out the screen as normal.
IMPORTANT: Always wash out from the SHIRT side of the screen. To
determine the best exposure, look for: edge denition and degrees of
unexposed emulsion. Properly exposed screen will have less slime. After you
have found your time, washed, dried and blocked out your screen and are
ready to tape. Post-harden your screen for strength and longevity by exposing
for another 10 - 15 minutes or placed in sun light for 5 minutes.

Example: 4,3,2,1 are for minutes and seconds. Four and 3 are for the minutes, so to get twelve minutes
you would press the 4 up once, and the 3 up twice. For 12:45s, you would press up on the number 4 once,
press up on the 3 twice, press up on the 2 four times and press up on the 1 ve times.
