LiteLOC sensor-to-screen calibration
The LiteLOC sensor-to-screen calibration is performed in the factory under specific setup conditions
which include the type of lens, screen, and the spectroradiometer used for measuring screen color and
brightness.
Your projector's setup conditions may not match the factory setup which may result in an discrepancy
in color accuracy. Upon first installation, check the accuracy of the color point and if unsatisfactory,
perform this calibration. Doing this calibration captures all the variables of your setup and achieves the
best results. By doing this calibration, you will not overwrite the factory calibration. Once satisfied,
some scenarios may exist in which you may need to re-do the calibration in the future.
Re-doing this calibration is required if the following is replaced:
• Color sensor board
Christie recommends re-doing this calibration if any of the following are replaced:
• Light engine
• Lens
• LOS (laser optical subsystem)
• Screen
• Port window
• Any other optical components in the optical path between the LOS and the screen
After replacing these components, check the accuracy of the color point and if unsatisfactory, re-do
this calibration.

LiteLOC sensor-to-screen calibration: Workflow

Identify the recommended order for performing the sensor-to-screen calibration.
• Create a new calibration file (on page 50).
• Recalibrate the calibration file (on page 51), if required.
• Edit the existing calibration file parameters (on page 52) on the Sensor-to-screen menu, if
required.
• Verify the calibration (on page 52), if required.
• Add the calibration file to the Channel Setup (on page 53).
