The previous step described how to calibrate the scanner. However, that's only half the story. We have only described the source colour space (i.e. the scanner);
we now need to make sure that what we see
in the Preview window and what gets sent to Photoshop are matched (the
destination colour space).
Press the Option button followed by the CMS
tab in the Defaults window and the Colour Management
should appear as follows:

The scanner profile in Step 2 will automatically be inserted into the
appropriate location (red star)
The next phase is to set the CMS dialog as follows: -
Colour Management
-
Input
- > Internal - should have automatically been
set to Colorsync (Mac) or Image Colour Matching (PC)
-
Internal - > Monitor - should be set to
Automatic (see note below)
-
Internal - > Output - should
normally remain RGB
Profiles for
ColorSync/ICM
-
Input - the correct scanner profile is
automatically inserted
-
Internal - should be set for
your preferred
Photoshop working space, e.g. Adobe RGB (1998), ColorMatch, etc. (see
note below)
-
Gray
- if you have a greyscale profile select it otherwise the Generic
Gray profile will suffice.
-
Output/Printer - will be greyed out and therefore cannot
be changed.
-
Rendering Intent - ideally you should leave it at
Perceptual although some users prefer Relative
Colorimetric for artwork
Embedded ICC
Profiles
- Embedded profile (not present on SilverFast Ai) - since you are using the IT-8 calibration
module this will read None. You can't change it and if it
shows anything other than none you will need to alter your scanner
application to prevent profile embedding
- Embed ICC profile - this should be checked

Figure 5 - Final Configuration of CMS Dialog
Important note: When
Internal->Monitor is set to Automatic it takes its cue for accurate
previews from the RGB Working Space as defined in Photoshop Color
Settings. Therefore it is essential that the SilverFast Internal
profile matches the PhotoShop RGB Working Space.
If Internal -> Output is set for RGB then the remaining settings
(e.g. Output/Printer and Plug & Play CMYK) cannot be altered. Finally click Apply
followed by OK. You're now ready to enjoy the benefits of
scanning images using a colour managed workflow.
Remember the Embed ICC profile checkbox MUST be selected and your
Photoshop setup for handling mismatched profiles must be
configured as described in the essay entitled Configuring
Colour Management in Photoshop 5,
Photoshop
6 and Colour Management or Photoshop
7 and Colour Management . If you haven't read these
then it is probably better that you do. Choose the version of Photoshop
that you use by selecting the appropriate underlined text.
