Default PDF image compression problem

I have to regularly prepare PDFs of a certain type of document including some branding logos on the cover, imprint pages and headers.

I edit a pro-forma Word doc with the changes, then use the PDFmaker (from version 6) to make the PDF.

Usually, but not always, the logos are badly "fuzzed up" by the conversion, as you can see from the attachment. The GIF screen shots are fine.

These are 80% quality JPEG files, placed in the Word document at 100% size at 300 DPI. The settings for Acrobat are High quality and to downsample images above 450DPI, so they should stay untouched. (The basic setting for the file is 600DPI.)

I've fiddled about with all sorts of settings but the only way I found to fix it is to paste in a fresh copy of the original image immediately before distilling. It usually seems to 'stick' for a couple of editing sessions, then goes blooey again.

Any ideas what's going on? I know Word's image management is problematic, but this is plain daft!

MS Word simply can't be used for DTP, because it has too many psychopathic issues. It's always something!! One thing after the other that is completely irrational. And these problems are not solvable; (it just always seems there should be a simple solution); but they will waste large amounts of time.

Fortunately, other programs are almost always set up to import easily from Word. (But not MS Publisher -- with it, importing from Word will go into psychosis). I would move to another program. You will save time and all the headaches.

George is probably right that MS Word is not the best tool for creating a PDF. However, you might tell us what version of Word you are using.

Others may have a better application for creating a good quality PDF.

I can't do that. The client wants Word as the source format.

This is using Word 2003 and Acrobat 6 - not a freebie PDF generator.

I've used Acrobat's Word to PDF converter add-in from versions 6 to 8, and they all work perfectly, although Adobe seems to have worked out a better way of doing it with each later version. I've only used it though with my organization's logo (something with an outer circle), for which the original was not done with JPEG (GIF, I think) and there have never been any jaggies.

NB Only v. 8.1 works with docx; even v. 8 can't cope.

I use that system all the time with no problems. I usually set the jpeg at 100% quality. Is it rgb? Do you generate the pdf by clicking the little icon in Word? And I hate to draw people away from this forum but I always get quick answers to Word problems at:

Tim - yes, it's RGB and any JPEG quality setting is problematic, and it's only this image in this document template that seems to go wrong. I may have a look at the MS forum - thanks for the link.

Lois--

The portion of the logo you've shown us isn't continuous-tone colour, so it seems to me that JPEG isn't the best choice of image format. PNG or GIF would probably work better (and might even compress smaller). Can you use Photoshop (or whatever image editor you use) to convert the graphic to PNG or GIF?

I've never used Word, so I'm not qualified to comment on it, but I do know that InDesign places Word documents, and its (InDesign's) PDF generation has always--for me at least--been bombproof. Even if your customer prefers to give you Word documents, it might be better for your sanity to work with them in InDesign on your system.

Good luck!

Lois--

Another thought: your message doesn't indicate what platform you're using, but the Mac version of PDFmaker was a very bare-bones affair that was good for converting only text and the simplest of graphics. If I wanted to be sure of good results, I always printed to PS and used Distiller to make PDFs.
