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

[Karen Farrell]

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

I forgot to add that I'm using a Xerox DocuColor5750 w/ Fiery XJ print driver to produce the PDF.

You should never use device-specific printer drivers to produce PDFs. The AdobePDF printer instance is specifically designed for PDF creation and is included with FM.

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!
