- You are seeing fonts you don't expect in the preview display when you open up an item in your CONTENTdm web site
You are using a font in your document that is not embedded in the PDF document and therefore is not displaying on the web site. PDFs have to have the font embedded in the file for it to display properly in the preview. Adobe has some help content on how to embed fonts in a PDF.
You'll want to have the Adobe PDF Converter installed on the machine and the ability to "print to PDF" in your printer settings. Once you have the new font embedded you should be able to re-upload it to the site and the fonts will display.
