OK. Let's take this example.
You've created a book with hundreds or thousands of images that you
have hand-tuned to CMYK using differing levels of black generation.
You've embedded profiles in the images so that you can easily manage
them for further editing, and have placed those images into many
different QuarkXPress documents with image update warnings turned on.
Rather than embedding the profile, I organize the images by project,
and simply keep track of the original profile that was used for
separation, either with the file name or by embedding the profile
name somewhere in the image metadata. Once I've converted the images
to CMYK, the different KGens are in the file, so I can use one single
profile to preview them correctly, and I just set my Photoshop
working space to that profile while keeping the images untagged.
Hence there's no need to strip or relink.
A second advantage of this approach is that you wind up moving a lot
less data around. In the kinds of books I do, images typically run
from about 800k to about 4MB of pixel data. The CMYK profiles run
around 2MB each, so if I have 1024 images, I'd be slinging around 2
gigabytes of redundant profile data. Not a huge issue for storage,
but a big one for transmission.
