reducing file size: how to compress large content stream, x object form & retain ADA?

Question

Hey gang: how to compress large content stream, x object form & retain ADA?

I haven't found a clear reference showing what page objects in InDesign create what size content stream items, or what size x object form data.

If I knew that, I might have a shot at manually reducing filesize?

I've reduced my placed Illustrator files by 50-70%, but InDesign still makes the same sized PDF.

Yes, I have transparencies and other stuff in the file - is that the underlying issue? It seems using PDF Optimizer breaks my ADA compliance schema if I use any adjustment to transparency. How can I reduce the filesize if I can't somehow reduce content streams without taking elements - or, transparency - off the page.

Maybe doing soething with my transparency when I export?

Any advice welcome - thanks!

Hi, @Scott.Olling ,"large content stream, x object form" can be anything, so more information is needed about the content of your ID-file.So you use text, forms, images, correct? Anything else like videos or others stuff?What PDF version is your PDF? Version 1.4, 1.5, 1.7?What settings are you using when exporting your PDF?Are you editing the PDF afterwards in Acrobat Pro or other software (which one)? "I've reduced my placed Illustrator files by 50-70% ..."How did you dom that?If the content of your Illustrator is only vector data the impact with ID is only small. BestStephan
