a) Engage the 3D system in the light path by enabling 3D Sync when selecting the test
pattern.
b) Mount a 3D glass or filter on the color meter to measure the brightness.
c) Select 3D Sync on the LiteLOC setup page.
d) Adjust the brightness level until you achieve the required brightness while the 3D system
is engaged.
14. To save the new laser file, select Save.
Creating a new laser file for external chiller-
based projectors
Create a laser file to store the power settings for the RGB laser light source and the maximum
expected relative humidity.
Only applies to: CP4440-RGB, CP4450-RGB
To make sure color and brightness are held at the required levels for your installation, enable LiteLOC
for each laser file you create. If you make significant change to the brightness level when refining the
laser power settings, it takes a few minutes for the color and brightness to stabilize.
1. Log in as service.
2. Turn on the laser.
3. For systems upgraded to v1.5.0 and already using the calibration file, set a channel to use the
appropriate calibration file (on page 62) and activate the channel (on page 68).
4. Display a test pattern, such as DC4K 17 L Point, to locate the center of the screen.
5. Set up the color meter to aim at the center of the screen.
6. In the left navigation menu, select Laser Settings > Laser Power/LiteLOC Setup.
7. Select the Display White Test Pattern slider.
8. To create a new laser file, select Create.
9. In the Create dialog, enter a name for the new laser file and select Create.
10. Set the maximum expected humidity.
The projector uses this information and the ambient temperature to determine the optimum
maximum brightness allowed.
11. In the White Coordinates dialog, set the required white point.
For a typical cinema setup, the white point is Digital Cinema Initiative (DCI) white x=0.314
and y=0.351.
12. Select Apply.
13. Adjust the brightness level until you achieve the required brightness at the specified white
point.
14. If the laser file will be associated with a 3D channel, complete the following steps:
a) Engage the 3D system in the light path by enabling 3D Sync when selecting the test
pattern.
b) Mount a 3D glass or filter on the color meter to measure the brightness through the
glasses.
