Looking back over an old post, I came across several issues that I
need clarification with:
1) There is an apparent discrepancy between what Chris suggests and
what is written in Real World Color Management:
There's no discrepancy. What I wrote in February were the settings you
would have to use in Photoshop's Print with Preview Color Management,
in order to mimic the behavior of using driver level color management
on OS X. Black point compensation isn't possible in the driver.
In RWCM (on p. 352), the figure shows Black Point Compensation as
being enabled. In this post, the recommendation is that it be
disabled. What's the current wisdom, and what's the rationale?
You will generally want to use black point compensation. The rationale
described on page 336 by the two bulleted descriptions is still valid.
2) Doesn't "Same As Source" accomplish the same thing here?
Print Space set to Printer Color Management (which is not an option
in Photoshop 7 in OS X for some reason): this is necessary or the
source space is not forwarded onto the driver/OS
No. Same As Source sends unmodified and untagged data. Printer Color
Management sends unmodified, but tagged data. The source profile is
included by Photoshop to the operating system which then uses that as
source instead of an assumed source profile (on OS X, Generic RGB).
3) What about the entry for "EPSON Stylus Photo <model_number>
Standard"? Should it remain at its installed default (i.e., just
changing the profile association for each media type that you've
custom-profiled)?
I'm pretty sure Standard is code for plain paper. If you aren't
printing on plain paper you don't need to worry about it. But the
bottom line recommendation is to not worry about this at all anyway,
because you should disable printer OS/driver color management and have
Photoshop do all the work.
