After building our publication in an INDD book file, I usually just send our print shop a PDF produced by choosing Print/Acrobat; the print resolution is fine, file size easily handled… but it never keeps the bookmarks or hyperlinks. To retain bookmarks, I have been using Export Book to PDF — which produces a monster 11Mb file that our webmaster refuses to post. Running the exported PDF through Acrobat's Reduce File Size knocks maybe 2Mb off the file size — still not postable (5Mb is our max).
But when I run it through PDF Optimizer (either after Reduce File Size or straight from the INDD Export), I see 'broken' characters — letters occasionally but frequently numbers — replaced by a rectangular box with an X through it.
The fonts used in the document are all Open or True Type, and the problem doesn't occur with HelveticaNeue and its family, only Minion Pro. I can send a sample page if viewing the problem makes it easier to understand.
Any thoughts? Thanks!
