Grayscale color management is not supported by InDesign.

Sadly so, I would add. :-(
I'm using for Grayscales a profile which
is derived from standard CMYK profiles by
Gray > Load Gray > ISO Coated.
This results in a Gray profile
'Black Ink - ISO Coated'.
InDesign CS2 shows this profile name by double-
clicking on the link (link informations).
So we know the profile, but IMO (also according
to previous discussions with Larry), InDesign
doesn't change the appearance depending on
By the way: for offset printing the Grayscale
should be pasted already in PhS into the K-channel
of an empty CMYK file with the same pixel size.
Now we have an ISOCoated file (accidently K-only),
which is probably handled like other ISOCoated
Best regards --Gernot Hoffmann
yes i make this to offset print.
i have ander question:
if i place grayscle from pS to iD - it's make black (k=100) rich
black wen i export to pdf press. but if i choose "no conversion"
in dialog box of "output" in iD, it's ok: the black it's k=100
it's because the grayscale in pS it's RGB value?
do you have any idea how make this k=100 from pS to iD
without "no convertion"?
sori abut may inglish... i from midlleast
It is possible to do a grayscale to grayscale conversion in InDesign in a roundabout way, provided that the destination profile is grayscale, i.e., you are printing one-color.
Here, your source and destination grayscale profiles will need to be replaced by CMYK profiles with GCR black generation set to 100%. InDesign can see these profiles, and the conversion will be K-only to K-only.
You can create max black versions of your grayscale profiles in Photoshop: just select Edit / Color Settings / Working Spaces / CMYK / Custom CMYK (this is a pull down menu), set GCR Black Generation to 100%, and fill in the necessary information for dot gain. Then save the profile via Save CMYK in the same pull down menu.
Things get a little more complicated if you don't have a grayscale profile of your destination to start with, but do have a CMYK profile. Here you'll need some way of extracting the K-only dot gain data from the CMYK profile to put in the max black profile that you create in Photoshop.
Hope this helps,
thanks Larry tseng! it's wokr!
