Required tools
•
Spectroradiometer.
•
Communicator software.
Preparations
1.
Setup the ambient light conditions
as it should be during the play out of the movie. (e.g. only the stairs and
emergency exit lighting is switched on).
Note:
In an optimal setup less than 1% of light from any other source than the light from the projector
should illuminate the screen.
2.
Configure the desired aspect ratio: e.g. FLAT or SCOPE (use most common aspect ratio). Do this by activating
the correct LENS file.
3.
Position the spectrometer perpendicular to the screen and measure in the center of the screen.
4.
Start up Communicator and follow the laser white point calibration wizard.
After white point calibration proceed immediately with color gamut calibration.
15.1.3 Color gamut calibration
Color Gamut
Color Gamut is the entire range of reproducible colors by a particular device such as a projector. The entire
range of reproducible colors are typically defined so that horizontal and vertical directions describe saturation
and luminance changes, respectively. When a color is "out of gamut," it is not possible to reach that color by
the device.

Why apply color correction?
During the post-production process of a film, a specific color space is applied. This color space is the Target
Color Gamut Data (TCGD). All movie content operates under that gamut. To ensure that in the cinema theater
the film is projected within the same color space as intended by the film industry, the color space of the
projector has to be corrected accordingly.
What has to be done?
The color coordinates for the projected primary colors must be measured on the screen. The values can be
different than those originally inside the projector due to reflection on the screen or due to the influence of the
glass between the projection booth and the theatre and even the projected colors are different from setup to
setup.
