Ok, I've got a third party PDF pasted in a document that I need to print as a PDF, and when printed as a PDF there's big white box's over the color background around every word with a shado, as well as a many pointed star with a shadow effect. The sudden unstranspaency effect doesn't appear in the Indesign document, just the PDF of the Indesign document, and it appears both when I print to the PDF distiller and when I export from Indesign.
What could be the cause and what can I do to fix it?
