Reply To: PDF woes with jagged-y text–help!

Unfortunately, I don’t have the solution to your problem, but I’m almost sure the culprit is the 93% transparency box that causes this issue. Is it covering the text? Is the text entered in this transparent box? These might cause it.

Try on more thing. Trash your preferences (https://creativepro.com/rebuilding-indesign-preferences.php), then create a new document and copy and paste one page to the new doc and try creating a PDF from it. If this comes out fine, it might be a transparency setting that you inadvertently set up.
