When to use Nikon CMS
In general, you can expect much better results with Nikon CMS
on. You may however want to turn color management off if:
• your computer has a slow CPU
On computers with a fast CPU, the processing required for
Nikon CMS consumes less time than the scanner needs to
scan an image. Consequently, turning Nikon CMS off will
have no effect on overall scanning speed. On computers
with a slow CPU, however, the scanner will have to stop and
wait while Nikon CMS processes the image. If your com-
puter has a slow CPU, you can try turning color manage-
ment off to speed scanning.
• you want to edit data from the scanner directly
Advanced users may want to turn Nikon CMS off to edit
uncalibrated RGB data from the scanner.
Keeping Colors True
Nikon Color Management
The Nikon Color Management System, or Nikon CMS, ensures
that the image data from your Nikon scanner are reproduced
consistently and accurately on your system’s monitor or printer.
With this powerful tool, you can manipulate colors using either
a CMYK or calibrated RGB color model before the data are
passed to your imaging application. Profiles detailing the color
characteristics of the chosen color model and the output de-
vice (monitor or printer) ensure that colors will be reproduced
accurately in almost any operating environment.
Nikon CMS involves two preferences tabs, one (the Gamma
sheet) for use when Nikon CMS is off and the other (Color
Management) for use when Nikon CMS is on. The Gamma tab
is where you specify how data from the scanner will be modi-
fied for display on your monitor. Because the monitor profile
can not be used when Nikon CMS is off, this adjustment must
be made manually. The Color Management tab is where you
turn Nikon CMS on and off and select the profiles for use with
your monitor and the CMYK and calibrated RGB color models.
