Thanks to a client's questions regarding our recommended CM work flow, I
was poking around the Adobe site's color management section and found
some contradictory information.
http://help.adobe.com/en_US/Photoshop/11.0/WS03037539-15A8-4250-BC64-30247EC7AFB6.html
"A.
Document is created in its working color space.
B.
Document’s color values are translated to color space of chosen proof
profile (usually the output device’s profile).
C.
Monitor displays proof profile’s interpretation of document’s color values."
This appears to say that the soft proof feature presents an
approximation of how the file will be printed if sent to the device.
This leads me to believe that the use of a profile for soft proofing
would guide the user to make corrections to the file based on the
characteristics of the output device. and not need to be converted to
profile.
Example:
Printer prints +5 G
User sees this on sofproof and adds +5M to balance.
File is sent to device and all is well.
However steps 5 and six contradict this, at :

"5. (Optional) Preview colors using a soft proof.
After you create a document, you can use a soft proof to preview how
colors will look when printed or viewed on a specific device. (See About
soft-proofing colors.)
Note: A soft proof alone doesn’t let you preview how overprinting will
look when printed on an offset press. If you work with documents that
contain overprinting, turn on Overprint Preview to accurately preview
overprints in a soft proof. For Acrobat, the Overprint Preview option is
automatically applied.
6. Use color management when printing and saving files.
Keeping the appearance of colors consistent across all of the devices in
your workflow is the goal of color management. Leave color management
options enabled when printing documents, saving files, and preparing
files for online viewing. (See Printing with color management and
Color-managing documents for online viewing.)"
This appears to imply that the optional use of a soft proof preview
would be followed up by a convert to profile. Since this is what
photoshop is doing when printing directly to a device with color
management options enabled.
So what IS photoshop actually doing at the softproof stage?
Is it showing an approximation of what the print will look like if the
file is sent to the device as is?
Or is it showing an approximation of what to expect with the file
converted to profile?
