Preserve Halftone Information--Check or Don't Check?

Question

I have a client that is about to send their manuals to press. We are not sure whether to select Preserve Halftone Information in the Distiller .joboptions file or not.
We are using FrameMaker 9 (unstructured), and the rest of the specified .joboptions settings are as follows:
Distiller v. 9.0
Compatibility:                          Acrobat 8.0 (PDF 1.3)
Color Images:                         Compression- Automatic, Quality- High
Compress Text:                      On (but I couldn't find this setting)
Color Conversion:                   Tag Everything
RGB Profile:                           sRGB IEC61966-2.1
CMYK Profile:                         U.S. Web Coated (SWOP) v2
The client asked about the halftone information, and I thought that I should probably find some more information.
Thanks,
Karen

Answer 1

AFIK the Preserve Halftone Info setting will only apply to EPS files, as
that's the only format I know of that may contain Halftone info. That's one
of the reasons I stay away from EPS files for bitmap images (unless they
require clipping paths)
In any case, if you haven't set EPS files to use a specific halftone
setting, it shouldn't make a difference. I doubt leaving it on will cause
any problems, and your commercial printer would be the best resource for
this question!
