Learn how to configure a laser file and use the projector's LiteLOC
Use the laser file to control the power settings of the red, green, and blue (RGB) lasers. The LiteLOC
feature ensures that color and brightness are held at the level you set.
Create multiple laser files to manage varying screen sizes, brightness requirements, and types of
content (such as 2D, 3D, and alternative content).
For external chiller-based projectors, the laser files also contain maximum expected humidity.
Creating a new laser file for CP4415-RGB,
CP4420-RGB, and CP4435-RGB
Create a laser file to store the power settings for the RGB laser light source and the maximum
expected room temperature for the projection booth.
To ensure 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 the laser on.
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 63) 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 Display White Test Pattern.
8. To create a new laser file, select Create.
9. In the Create dialog, type a name for the new laser file and select Create.
10. In the White Coordinates dialog, set the required white point.
For a typical cinema setup, the white point is DCI white x=0.314 and y=0.351.
11. Select Apply.
12. Adjust the brightness level until you achieve the required brightness at the specified white
point.
13. 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.
