Document Overhead in Audit Space Usage??

[R_Wong17@adobeforums.com]

Exactly what is this and how can I reduce or get rid of it. I have had several pdf's where it is over 50% of the document size. I am able to reduce the photoshop images with plugins, and the "reduce file size" pdf optimizer, but the Document Overhead does not reduce in size. Is there any plugin that can help with this. (I am on a PowerMac G5 with OSX Tiger and Acrobat 7)
Thanks for any assistance.

No basically the tell you how much is devoted to fonts used and other items.

The only way you can reduce some of these like percentage used by fonts would be to unembed fonts not need or decrease the dpi of images. An Audit is just telling you howmuch of what is being used and how its used.

Thanks for the info.

But I am a little oonfused. In the Space Audit, it already has a catagory for images, (in the case of the pdf I am working on, it is about 40%) and a font catagory ( about 1%). The content stream is about 20% while the Document Overhead is 45%.

Are there any other elements that can be changed in my original layout besides reducing image dpi that can get this number lower? (It doesnot always have a large number for Document Overhead, just on certain pdf I get from freelancers)
Thanks

Cancel the Audit. The go to PDF Optimizer (PRO only) then change DPI of Images color and B&W. (save the original setting on paper somethere. Once this is changed it stays the same until you change it again.

A save-as is sometimes all you need to perform - just depends upon the
content itself.

Overhead might be unused data from an Illustrator PDF or even its own
index so it knows how many pages are in the document ...

I also have pdfs where the Document Overhead is 70%. I've used the Optimiser/Save As etc. to reduce everything I can but the Document Overhead will not reduce. Any ideas?

Did you try "save as" to a new document name? (Not replacing the current version, but a whole new one.) That worked for me.

This should not make any difference whatsoever. Do you have any evidence
to support this ?

Jon,

I am suggesting the same thing you are but name it different so it doesn't replace the current version (that would be the same as saving.) I don't know if you understood what I was trying to explain.

I had a document that was a ridiculous size on the document overhead (named Test). When I used the "save as" function, and just saved over my current "Test" file, the document overhead did not change. However, when I chose "save as" and saved it as "Test1", the document overhead reduced dramatically. That is what I was implying to the person before me.

Thanks for the suggestions but these were tried early in my attempt to reduce file size. Document Overhead is by far the largest percentage of file size and Save As (either with the same name or another) doesn't affect this.

I'm having the same problem. I also tried save as with no results (trying a few different times to be sure). This was never a problem with CS3 and acrobat 9pro - very frustrating.
