LiteLOC calibration for cinema projectors
The LiteLOC 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 a 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
Re-doing this calibration is optional if any of the following are replaced:
• Light engine
• Lens
• LOS (laser optical subsystem)
• Screen
• 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.
