tested the original scanner profile on a number of images and you are
sure the profile needs editing. In most cases, a well-built scanner profile
will work as you expect the first time you generated the profile.
Pipeline Considerations
If the original data saved from the scanner is untagged you will need to
assign a profile to each scan. With large numbers of such untagged scans,
you might want to use a utility (or Photoshop) to embed the profile as a
batch process (see Chapter 8 for options for batch processing ICC pro-
files). Some utilities can be used to assign the scanner profile and convert
the scan into your working space. You don't have to deal with Photo-
shop's

warning dialog. You will not have the benefits of the
Adobe ACE
engine and other conversion options unique to Photoshop.
However, you can greatly speed up the process of scanning and conver-
sion to ultimately bring the documents into Photoshop.
If you have a scanner that is fully ICC aware, you have options in
data handling. Let's assume you have scanned the image in the scanner
RGB color space. I would recommend you consider saving this original
raw scan since this represents the widest gamut data you were able to
capture. Since you have a scanner that allows you to utilize input pro-
files, the software very likely will allow you to embed the scanner profile
into the document. You can edit these scans in the scanner color space
within Photoshop. Spot the image, do fine cropping, and perhaps apply
a bit of capture sharpening. The data is now ready for archiving and can
be converted into any working space you wish. This is a good way to
handle the production of scans for other users. You may not know what
working space they want to use. When they open the scan in Photoshop,
they can convert into the working space they prefer.
You might decide to scan and convert on-the-fly into your working
space, which is a real time saver. The downside is you lose the original
high gamut data from the scanner. If producing the maximum amount
of work in the minimum amount of time is your goal, scan and convert
from the input profile to your preferred working space and move on. You
will be able to open the documents in Photoshop with no warning and
continue with the process of spotting, cropping, and sharpening.
A rare number of users they may wish to scan directly into a
print/output space and send the documents directly to the output device.
The downside is these scans can be output only on this one device so this
is a very inflexible pipeline. However, the time savings are tremendous.
This continues to be a common pipeline used by those in print and pre-
press environments.
