Viewing booth for hardcompy comparison only
A viewing booth that is being used for comparing print and proof, is
supposed to show an illuminance value of 2000 lux ± 500 lux and a
color temperature close to D50.
Attach the ambient light head to the instrument and hold the instrument
towards the back wall of your viewing booth. Make sure the background
is a neutral gray. When in doubt, use a gray card that has no metameric
failure, like the basICColor gray card.
4.10.5 Adjust viewing booth
Using this setting will adjust the lightbooth's brightness to the brightness
of the monitor. Only then it will be possible to compare a photographic
print, proof or any other artwork with the display on the monitor.
SpectraView Profiler 5 communicates with the lightbooth and will
automatically adjust its brightness to the monitors brightness. Please
take notice that the monitors brightness should be set to a standardized
value. The ISO 3664 requires a luminance of 500 +/- 125 lux.
Other settings are also possible but then they are not standardized and
other users may not have the same exposure at their facilities.
Viewing boot for hardcopy comparison only
By using this setting the light booth will be automatically adjusted to a
luminance of 2000 lux. This is the standardized luminance to compare
artwork, photos and/or press prints to proofs.
This setting should not be used to compare (e.g. a proof) with the
display on the monitor.
