WHITE TOLERANCE NOTES:
The chosen target for white (White x/y) coordinates under Target
(TCGD) may be relaxed, if desired, by establishing a small tolerance
box around it. This box represents four coordinates (0-1-2-3) plotted on
a 1931CIE Chromaticity graph, and may vary from TCGD to TCGD. If
desired, define new tolerance coordinates for the current TCGD to
increase or decrease this tolerance area, or to change its shape or
location-larger boxes relax the tolerance, reducing the loss of light
caused by precise matching.
Clear the checkbox if the projector's whites must precisely match the
target white point (typical for telecine use) defined for the current
TCGD. If this match can be anywhere within the tolerance box (typical
for theatre use), enter a checkmark. The checkbox status is saved with
the TCGD. Keep in mind that some light is usually discarded for an
exact match, resulting in a dimmer image-it is recommended that you enable the tolerance box for all
applications requiring maximum brightness, such as in theatres. Do not enable the tolerance box if exact color
performance is more crucial than overall image brightness, such as in telecine applications.
RESTORE NOTES:
This button enables you to return to the Gamut menu settings that were present when you opened the menu,
however the precise behavior depends on whether you are working with measured (MCGD) or target (TCGD)
settings.
To Restore MCGD Settings:
The Restore button is disabled unless you have used the Test button. To cancel new MCGD settings and return
to the previous MCGD settings, the new settings must be tested (via Test button) but not yet saved. If not yet
tested, you can either leave the menu and cancel the settings as requested by the dialogue box, or attempt to
save but cancel out of it. If you have already saved a new OnSite file (by pressing the Create MCGD button),
the old OnSite file cannot be restored.
To Restore a TCGD File:
Select the Restore button any time before saving.
