Hello everybody,

After some research, we have identified a strange (and funny) InDesign
CS (for Mac) behaviour working with fpo OPI images. This is the case:

I work in a newspaper and we have used InDesign for several years. In
our workflow we use an OPI server (Intersep by WaveCorp) and we have
worked fine from InDesign 1.5 to InDesign 2.0.2. Now, we started to
work with InDesign CS, but when we printed a document to postscript we
realized that InDesign CS always removes the fpo opi comments.
Obviously this is a big problem because our OPI server cannot
substitute the fpo images for their hi res version.

When doing the same test (with the same fpo eps) with InDesign 2.0.2
the postscript preserved the OPI comments!

Again, we did a new test but now we generated the fpo eps image with
other OPI systems like Fullpress and Helios, and in both cases there
was no problem, the resulting postscript file preserved opi comments.

Then we realized that the problem was just with images generated by
Intersep. And now comes the strange/funny part. These are the first
three lines of our Intersep fpo eps:

%!PS-Adobe-3.0 EPSF-3.0
%%Creator: Adobe Photoshop Version 7.0.1
%%RSIPreScreenedImage: positive

After doing a lot of experiments we found that the problem was at the
second line. We changed it to:

%%Creator: Something

And it works! The opi comments was not removed! Furthermore, we
realized that the problem is related with the string "Photoshop" :

%%Creator: Photoshop <--IT DOESN'T WORK
%%Creator: Adobe Photoshok Version 7.0.1 <--IT WORKS
%%Creator: Photoshok <--IT WORKS

Apparently InDesign CS doesn't like Photoshop :-)

Tests with Helios and Fullpress worked because they change their
creator to :

%%Creator: Fullpress
%%Creator: Helios OPI Version 2.1


To me this is a InDesign CS bug. I will report it with Adobe. What do
you think? ...

Regards!
