Clearly the appropriate profile to select depends on assorted settings

assorted modes that result in different profile selection with
ColorSync. Some drivers do this. The driver for my Canon i960 does.
The user interface problem is that the mode names that show in
ColorSync Utility have NO OBVIOUS relationship to the print dialog
user interface. To this day I don't know what "PR1" and "PR2"
correspond to for the Canon i960.
Those choices were made by Canon, not Apple. Likewise some developers
with multiple media type settings will only register one media type, or
"mode" with ColorSync Utility.
Things need to be done by driver/PDE writers:
1) Get consistent with the printer mode naming between the dialog
boxes and the modes registered with ColorSync. This should be REALLY
EASY to do. We are just tasking about some meaningful text labels
here. Nothing more.
I'm not a developer and I haven't read the development material on
this. So I have no idea how easy it really is to do, but so many print
driver developers are having problems with this that I'm suspicious of
documentation lacking somehow. Maybe it's a language barrier problem.
2) Actually use the profiles registered with ColorSync. This should
be REALLY EASY to do. I wonder if this isn't commonly done because
printer vendors don't trust third party control and they don't want to
deal with support issues that involve what they consider to be
incorrect profiles.
For cross platform parity I suspect the print driver vendors will
continue to default to using proprietary color management. This could
change if...
3) Provide feedback in AT LEAST the print dialog Summary pane of what
profile will ACTUALLY be used by the driver when setting up the PDF to
raster conversion (which is where the color mangling happens in tioga
drivers).
Again, I'm pretty sure this is a driver problem. If it doesn't report,
live, to the OS what the ProfileID is for the current settings, the OS
can't do anything about it except provide the same bogus information
the print driver is.
