The color.org web site has an interesting test page that
characterizes your
system's ability to support version 2 and/or version 4 ICC profiles:

The strange thing is, when I use Safari 1.3 under 10.3.9, the test
shows the
system supports version 2 and 4 ICC profiles. But the same test
using Safari
2.0 under 10.4 shows the system supports only version 2 ICC profiles.
I have the same problem in OmniWeb and IE. The PDF version displays
correctly in all web browsers, as I have the Adobe Acrobat 7 PDF
internet plugin installed, so ACE is probably being used in that
case. When I save the PDF version of the test file, it looks fine in
Acrobat 7, but the top two quadrants (the ones containing v4 profiles
embedded) are simply missing. There's just white space there.
So I'm thinking this is a ColorSync bug. If that's the case, this is
a pretty big bug.
Is this a valid test? If so, any clue why Apple has taken a
backward step?
And what are the implications for color management? Will a failure
to use
ICC version 4 profiles really make much difference?
It's a valid test but I wonder how many people are actually making v4
profiles at the present time considering the inconsistent support.
Windows has no native support, and many RIPs on the market still puke
when they come into contact with a v4 profile.
