The Scanning Process The illustration below shows the role Nikon CMS plays in the scanning process. CMS profiles are shown in blue, user operations in red. When Nikon CMS is on, uncalibrated RGB image data from the scanner are converted to grayscale, CMYK, or calibrated RGB, depending on the color model selected in the scan window. CMYK data are processed according to a user-specified CMYK profile, while RGB data are processed according to the profile selected for the calibrated RGB color space. These data are stored in memory so that the color model can be changed without performing another preview scan. Any changes you make using the color enhancement and Unsharp Mask tools also apply to these data. When the image is displayed in the preview window, the monitor profile is used to ensure that the preview image is as true as possible to the data in memory. When the Scan button is clicked to perform the final scan, the scan data are processed according to the selected color-space profile and any changes that were made using the color enhancement and Unsharp Mask tools in the scan window. The data are then transferred to the host application or opened in image windows in Nikon Scan. Where possible, the color-space profile is transferred to the host application together with the image data. The TWAIN interface used in Windows, however, does not allow profiles to be passed to another application, with the result that under Windows the profile is only transferred to the host when Nikon Scan is used as a stand-alone application. (note that profile information is lost when the image is saved in a format such as BMP that does not allow the profile to be recorded). When images are displayed in Nikon Scan image windows, the monitor profile is used to ensure that the image on the screen reflects the original as closely as possible.

The Scanning Process
The illustration below shows the role Nikon CMS plays in the
scanning process.
CMS profiles are shown in blue, user opera-
tions in red.
When Nikon CMS is on, uncalibrated RGB image data from the
scanner are converted to grayscale, CMYK, or calibrated RGB,
depending on the color model selected in the scan window.
CMYK data are processed according to a user-specified CMYK
profile, while RGB data are processed according to the profile
selected for the calibrated RGB color space.
These data are
stored in memory so that the color model can be changed with-
out performing another preview scan.
Any changes you make
using the color enhancement and Unsharp Mask tools also ap-
ply to these data.
When the image is displayed in the preview
window, the monitor profile is used to ensure that the preview
image is as true as possible to the data in memory.
When the
Scan
button is clicked to perform the final scan, the
scan data are processed according to the selected color-space
profile and any changes that were made using the color en-
hancement and Unsharp Mask tools in the scan window.
The
data are then transferred to the host application or opened in
image windows in Nikon Scan.
Where possible, the color-space
profile is transferred to the host application together with the
image data.
The TWAIN interface used in Windows, however,
does not allow profiles to be passed to another application, with
the result that under Windows the profile is only transferred to
the host when Nikon Scan is used as a stand-alone application.
(note that profile information is lost when the image is saved in
a format such as BMP that does not allow the profile to be
recorded).
When images are displayed in Nikon Scan image
windows, the monitor profile is used to ensure that the image
on the screen reflects the original as closely as possible.
