In my ongoing saga in re-evaluating Apple's profile handling , I have
some burning questions.
In the Colorsync Utility if a device (cmyk color printer in this
instance) is set up with a profile, then I assume all color data
going to that printer will be converted using that profile. So this
looks like an output/destination profile mechanism. How does the
system know what the source profile is?? Does it use the default
profile set up in the ColorSync Utility preferences?
In other words, if I want to color manage an application, say Quark 6
for example, but don't want to use Quark's built-in CMS (mostly
because it only handles tiffs and built-in colors), can a zero
conversion be done at the Quark level, then have the default CMYK at
the system level be set to "US Web Coated" or whatever, then the
device (the color printer) set in the ColorSync Utility to the output
profile of the printer?
Ok, now... so what is the difference between all of this and creating
a "filter" in the ColorSync utility? It appears this is just another
way to make an output/destination profile available at print time.
But again, where is the source profile specified? There is a
"default" setting for the filter which is set independently of the
profile, and the text says "profile to use when no profile is
specified in the document." So is this the source profile?
A problem here is that Apple is trying to make this easier for Joe
DesktopPublisher to understand, but in the process has dropped
standard terminology that would let us know where the source profile
is.
One more thing. Do these filters convert all color data? EPS files, etc?
Is there detailed documentation or evaluation on this somewhere?
