PDF file size out of Illustrator
Posted 09 April 2009 - 11:16 AM
First off, I simplify lines and polygons in Arc or Illustrator, whichs shaves off anywhere from a 100 KB to a MB or so.
Out of CS3, I've been unchecking "Preserve Illustrator Editing Capabitilities", "Embed Page Thumbnails", and "Create Acrobat Layers from Top-Level Layers", and checking "Optimize for Fast Web View"... or just use the "Smallest File Size" Adobe PDF Preset.
That brings the file size down considerably from the AI and a regular PDF file... but I've also been able to shave a few more hundred KB's, and up to a a few MB's on some file depending on whats in them, after I go into Adobe Acrobate and either save as "optimized" or go to "reduce file size" under the "Document" drop down menu.
Anything else I can do, without converting it to a raster image?

Have you tried: Document Menu> Examine Document> This will allow you to delete hidden page content along with other types of information. Not sure this going to help you coming out of Illustrator, but it's worth looking at.
It did reduce it a little bit. One document I took off about 60KB, although that was after I did went through "Examine Document" and then "Reduce File Size" again.
On another file, it knocked off 200KB (more than 20%), and then I did "Reduce File Size" again, and it added 100KB...

You can further tweak settings for more optimal results.

Have you checked your raster effects settings in Illustrator? I think that it is Effects, Document Raster Effects, and then make sure it is set to 72dpi.

This finalizes transparent layers, so the graphics program is not modifying the image to display it, and the pdf generator is not trying to write a pdf that reproduces it.
Remember too that a small image (say, in the legend or for the map cover panel) will be handled by the software as a small opaque bit on a transparent layer. Thus, any discontinuous image, any image that does not go from one edge of the inked area to all the others will have at least some bit of it as transparent once it is rendered for printing.
