Thanks for all the comments re Quark's CMS. The first
time I did the test I used CMYK EPS files that I
wanted to convert to a different CMYK space. Sounds
like there might be 2 problems with that idea. If I
have an embedded profile in the image for CMYK and I
want to convert to another CMYK color space, Can I
drop the embedded image into Quark and expect it to
convert if I use the CMS?
No, because you're using an EPS. It has to be a TIFF--period. Save
the EPS out of Photoshop as a TIFF. And when you say you want to
convert to another color space, I'm assuming you want to convert from
the embedded space to the proofer space, which happens when you send
it to print.
Or would I have to use the
"composite simulates separations" which I guess you
folks are stating doesn't work, right? So is the
answer 'you can't do a CMYK to CMYK directly in
Quark?'
This command attempts to simulate the press on your proofer. If the
initial conversion isn't there then it won't help. CMYK (embedded
source profile) to CMYK (output profile) works fine but it has to be
a TIFF or QuarkXpress just shrugs.
The second time I did the test I used RGB TIF files to
convert to CMYK. Now I see different results as
expected. Does anyone know what CMM uses Quark uses if
I have ColorSync set to Automatic?
Just change the CMM so it's not "Automatic" then you'll know. But you
would get better results if you converted to CMYK in Photoshop, then
brought them into Quark.
When I did the
second test with RGB TIF files I did a P2P in
photoshop from RGB to CMYK and then took the same
image in it's RGB state w/ the embedded RGB profile
and told Quark to use the CMYK profile on print. So
they don't match well as expected. There is no control
for rendering intent or CMM. I guess that leaves a
workflow decision from someone to make. How can one
decide which way is better OR right?
Again, don't let Quark do the conversion, especially since you have
so little control. Do it in Photoshop first.
