Tip
4. Place the new lithopattern or effect into the aperture.
Install lithopatterns with the coated side away from the lamp. Install effect glass
with the smooth side toward the lamp.
To determine which side of the litho is coated, place the tip of a pen against each
side of the litho and view it from a slight angle. On the coated side, the tip of the
pen appears to touch its reflection. On the uncoated side, there appears to be a
gap between the pen and its reflection
Note: To create a moire effect in position 3 or 7 of Gobo 1, install the rotating
and static lithos with the coated sides together. In this case, the rotating
lithopattern would be the opposite of the other lithos in the wheel.
5. Replace the spring.
6. After replacing the lithopattern or effects glass, clean it by using a soft, lint-free
cotton cloth and a mild glass cleaning solution (containing no ammonia).
Replace the bezel (see Figure 5-1 on page 5-1).
