I wonder why they say that there is no "No Color Management" option inthe
printer driver when the option is there, at least on Windows driver
(Printing Preferences-->Main-->Color Settings-->Matching-->Color
Correction-->Off).
I'd suspect that they may be referring to Apple/OS X.
A lot of the printer driver/operating system/application
color profiling problems seem to occur on Apple/OS X.
Let's assume that there is no "No Color Management" option in the printerI
driver and I print the targets with the PSP plugin. So far so good. When
want to print from Lightroom with the resulted icc profile how do Idisable
the color management in the driver (since there is no option)?
You don't. You've made a profile and (presumably) installed it.
If things work as intended, the normal workflows should make use
of that installed profile to correctly manage color.
Since things don't work as intended it's easier, "cleaner" and safer to
able to print test patches with color values that you can
control at the point in the workflow where the output of
a destination color profile inverse lookup would occur. That's
why the safest way of being able to make profiles is to be
able to null out the color management transform (source profile
to destination profile transform). "Safest" meaning that
by minimally disturbing the workflow, any quirks or changes to
the workflow are taken into account by the color profiling.
[ This is a point that I had very great difficulty making many of
the Wayland folks appreciate, assuming I succeeded at all. Too
many people seem to jump to the conclusion that "raw" access to
the device is paramount, whereas access to the point in the
workflow where the profile takes effect is actually what's needed. ]
