Okay, I'm now puzzled by this. In "ColorSync on Mac OS X"
(http://developer.apple.com/technotes/tn/tn2035.html) under the
heading "ColorSync Changes for Mac OS 10.2"
Profile Changes when Printing or Displaying Untagged Data
PDF Display
On Mac OS 10.2, untagged RGB data in PDF will be tagged with the
Generic RGB profile, and as a result it will be color-matched to the
screen.
This isn't how it works in Panther's Preview or Mail applications. I
have an RGB test file, which is a PDF, with specific RGB values
(solids), and digital color meter shows those values that are in the
file. If I make a copy of this image, assign Generic RGB, embed and
save, then hand it over to Preview or Mail the numeric values differ
from what's in the file. So I conclude in the first case that untagged
documents, including PDF, assume monitor RGB in Panther, not Generic
RGB, nor per the message in the ColorSync Utility>Preferences window.
I thought I had an idea what direction ColorSync was going on the
platform and now I'm pretty confused as to what's going on. I'm feeling
like we're playing the color management equivalent of the hokey pokey.
