All:
The Generic profiles are just that... generic. ColorSync needs a basic
description of RGB, CMYK, LAB, and Grayscale in order to convert between
untagged image data in these spaces and a destination profile.
There are only a few instances when these profiles are even used. One
example would be an application such as Microsoft Word that does not yet
have facilities for assigning profiles to images.
1) Open the ColorSync Control Panel (or System Preference Pane on Mac OS
X) and note the settings. Most users never change these preferences, so
the Generic profiles are often used to define the source color spaces
for untagged images.
2) Create a Word file with a combination of RGB, CMYK, etc. images that
DO NOT contain ICC profiles;
3) Print that file using the Apple LaserWriter 8 driver and the
ColorSync color matching option;
4) The driver looks to the ColorSync Control Panel/Preference Pane for
the current user-selected default profiles for documents and devices and
uses these to convert to the printer's profile.
The bottom line is that it is much better to tag your images with
profiles relevant to your individual workflows or chosen "working space"
than to use the Generic profiles.
If you would like to make suggestions for changing the default profiles,
I'll be happy to discuss options.
