Disable ColorSync entirely?

with its printer driver. It appears to be the case that no matter what I
do, I can't turn off ColorSync management of printer output. Whether I
select "No color management" or "ColorSync" in the printer settings, the
ColorSync profile assigned to the printer is always applied -- if, for
instance, I assign a different colorsync profile, I see the changes in
either case.
This is a problem because it prevents me from doing color management within
PhotoShop. I realize that not disabling ColorSync for output when
"No color management" is selected in the driver settings is probably a
driver bug, but I've seen many reports of this and Epson doesn't seem to
be doing anything about it.
Is there a "null" ColorSync profile? Or some other way to just take CS
out of the printer output path entirely? The ColorSync utility seems to
be unwilling to, for instance, delete profile assignments to printers; in
fact, I note that I just about can't delete _anything_ from it, not even
printers that I removed from the printers panel long ago...
I'm using 10.3.3 and Photoshop 7, if it matters (I suspect it doesn't).

Where exactly do you "assign a different colorsync profile"? If you do
that to the image in Photoshop, it is logical that you will see changes.
That is supposed to happen.

Uh, no. If I use the *ColorSync utility* to assign a different profile
to the printer, I see output changes -- even if I have "no color management"
selected in the printer driver.
The problem is *precisely* that I *cannot* effectively manage color in
PhotoShop because it appears to be impossible to prevent ColorSync
processing by the printer driver at output time. If I apply color management
in PhotoShop (for example, by selecting "color management" in "print with
preview" and applying an appropriate profile), then tell the printer driver
to not manage colors, what actually happens is that color management is
applied *twice*: once by photoshop, once by ColorSync in the printer driver.
Obviously, that's not what I want. I want color management done once, by
PhotoShop, and not done at all by the printer driver. I just can't figure
out how to make that happen.

So what makes you so certain that the standard color profile that is
assigned to the printer isn't your 'zero profile'? Thousands of people
do just what you describe. They use color management in Photoshop and
tell the printer driver not to manage colors. And they get excellent
results. I'm one of them (using an Epson 7600 Pro, which is a 'big
brother' of your printer).

Maybe I understand things wrong, but isn't the behaviour that TL is
seeing exactly what ColorSync is all about? Meaning matching as best as
possible what he is seeing on screen to what is printed on paper.
After all the screen is a RGB and the printer a CMYK device so without
ColorSync or another color managment solution it is impossible to get
the best possible match. I don't know if in PS he set the CMYK preset
to his Epson profile or to something else (or nothing), but if PS and
the printer have different profiles assigned I guess odd things will
happen.
I would try as a possible solution to remove the preference file from
~/Library/ (assuming OS X is in use) to see if the printer then behaves
like you want it to.

Well, let's see:
1) I can see using a profile-editing tool that it's not.
2) Epson told me it's not.
3) Replacing it with the latest Epson profile for the relevant paper type
produces almost-identical results. Or will you now claim that they're
_both_ "zero profiles"?
4) If that were the case, turning on color management in PhotoShop wouldn't
produce obviously double-corrected results -- which it does.

I am entirely aware that this *should* work. What I'm trying to figure
out is why on earth it *doesn't*.
Given that I get exactly the same results whether I have "no color management"
or "colorsync" selected in the Epson driver panel, and that changing the
profile assigned to the printer in the colorsync utilty changes *both* the
"no color management" and "colorsync" output, it seems pretty clear to me
that, for some insane reason, the current SP2200 driver is color managing
even when told not to. AFAICT, this makes it basically impossible to
use PhotoShop's color management in any sane way.
Rather than telling me that I can't possibly be having the problem I'm
having, how about suggesting some way to _not_ have it?

Get off your high horse. I'm not saying you can't possibly have the
problem you're having. I you say you have a problem, you have a problem,
period. I'm just wondering if the _cause_ of the problem isn't somewhere
else. If the cause of the problem was what you state, then EVERYBODY
using MacOSX and this Epson printer should have that problem and I don't
think that's the case.
Let's forget ColorSync Utility for now. You cannot disable it, so there
is nothing you can do there. Other people haven't disabled it either.
Can you describe step for step what you are doing when you print with or
without color management in Photoshop? Is the image RGB or CMYK, where
and when do you use your profiles, how do you setup the print dialogs,
etc.
