Section 2: Installation and Setup

2.10.1COLOR CALIBRATION

After the CP2000 is installed and all components are mechanically aligned for optimized light output

and geometry at the screen, its electronic system processing must be calibrated to ensure accurate color

display in the new environment. In this one-time global calibration, the installer measures initial colors

at the screen and enters this data (Measured Color Gamut Data) into Windows-based DCP Librarian

software installed on a laptop. The software then calculates precise corrections needed for regaining

the desired color performance (Target Color Gamut Data) and essentially compensates for the type of

port window (if present), screen, lens, light output, ambient light and other current environmental

factors that affect color performance. Results are defined in a file, activated and downloaded to

projector memory to be used as a basis for all future displays.

If there are changes to the environment in the future (for example, a new screen is installed), the

CP2000 should be re-calibrated. Correction for proper color balance sometimes reduces overall light

output.

NOTE: Most gamut functions are also now available in the TPC Gamut menu (password required).

Multiple MCGD files can be saved for use in different situations, such as when an anamorphic lens is

swapped ON and OFF the projector.

2.10.2ELECTRONIC SCREEN MASKING

DCP Librarian also provides a powerful masking tool for precision cropping of the image to correct for

geometry problems, such as a keystoned image. The effect is similar to aperture plate filing typically

done for correcting images from film projectors. As in the calibration of color, screen masking

adjustments are global - that is, you can create a variety of masks and download them to projector

memory for use with sources. Mask settings are distinct from aspect ratio or screen position settings.

NOTE: Most screen functions are also now available in the TPC Screen menu (password required).

PCFs (rare): Numerous settings collected into a single Projector Configuration File further control

processing variables for optimized display of specific source material. Each PCF file, typically created

in DCP Librarian, pre-defines color space, target color gamut, source aspect ratio (resolution), and

gamma (a.k.a. "degamma") settings for a cinema or non-cinema source. Once the collected settings are

downloaded to the projector's internal memory, their "PCF" can be assigned to the corresponding

CP2000 input connection and quickly applied via a controller such as Christie's Touch Panel

Controller. No further adjustment in processing should be required.

Refer to the DCP Librarian User's Manual for all DCP Librarian Setup Software operating details

and procedures.

2.11 PHASE BALANCING

As a final step in any installation, adjust the ballast phases to minimize ripple from the available AC.

This helps eliminate on-screen flashing in mid-range grayscale images. Refer to the 3-Phase Ballast

Ripple Adjustment Instructions supplied with the projector.
