SilverFast differs from many of the free offerings from vendors
such as Canon,
Epson, et al in so far as colour management is at its core rather
than an after-thought that really does little more than squeezes
our images into the sRGB colour space. On the other hand
SilverFast incorporates two
important colour mangement functions:
- Automatic colour matching with Photoshop to ensure that what
you see in SilverFast is what you get in Photoshop
- An integrated IT-8 calibration module (optional extra) or
scope for assigning a third party custom scanner profile. Both
methods ensure that SilverFast has match the colour
rendering characteristics of the scanner.
The following is a short explanation of the various possibilities
for configuring the SilverFast Colour Management Settings
(CMS) dialog. The settings shown are compatible with SilverFast 36 to 24bit colour, 48 bit colour
or HDR colour modes.
The CMS window has four separate sections which are used to determine
the extent to which SilverFast will manage the colour of your
images. These are:
- Colour Management - In this section we define whether
and/or how SilverFast will integrate with the PC operating
system and image editing applications such as Photoshop.
- Profiles for ColorSync/Image Colour Matching - In this section we
select the various Input profiles (scanner/camera) and Output
profiles (e.g. Photoshop working space) .
- Embedded ICC Profiles - In this section we decide whether
to enable profile embedding. Remember that embedding an ICC profile
is the means by which other applications can decode the colour
recipe used when previewing and editing our images in
- Plug&Play CMYK - This section is only relevant when the
user has chosen to export scanned images in CMYK.
Using the above settings mean that SilverFast will NOT manage
the colour of your documents and NO profile will be embedded
within the document. Furthermore, the document previewed on your display is unlikely to
match that which finally appears in Photoshop.
As with the previous example you are instructing
SilverFast to NOT colour manage our documents. However, in
this instance you're embedding an ICC profile that describes the
scanners colour rendering characteristics. So we could
describe these settings as providing a function "similar" to the Assign
Profile in Photoshop 6, 7 and CS. Again, the preview display
will NOT be a true colour representation of how the image
will appear in Photoshop.
For normal scanning the settings described in this example are NOT
normally recommended. However, by embedding the
scanner profile it does at least provide colour savvy applications
with some knowledge as to how the document should appear. It is also
one of two possible CMS configurations when scanning for archive
purposes. The other method is described as
