Is printing from Preview working properly at the moment, for a "no
color adjustment" workflow?
In other words, can one print profiling testcharts reliably from
Preview?
There isn't a way to bypass printer driver color management using
Preview.
Preview always associates a source profile with the image data sent to
the printer driver. The printer driver has a list of modes, each of
which has an associated destination profile describing the printer's
behavior. The image data gets matched from the source profile to the
destination profile unless those are identical. For printing a test
chart you'd want to first determine which mode your printer is going
to use (based on the paper type usually) and which profile the driver
has assigned to this mode. You can determine this with ColorSync
Utility. Once you know that destination profile, you could embed it
into the image data or in Preview use "Assign Profile". If the source
and destination profiles are the same, no matching occurs.
However you're left with the possibility that the printer may add it's
own proprietary color tweaking. Whether or not you can turn that off
is up to the driver. So the answer to your question is it's possible,
but it depends on the driver because you can't bypass the driver.
