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.
