I have an issue with the PDF files generated by the "Print to PDF" functionality in Tableau. While the PDF itself is readable and appears to work ok, in Acrobat X I can not add a watermark to the file. If I use File->Print and use a PDF printer the results don't look as nice and the fonts get messed up, but the PDF can be watermarked. I've tried a number of other raster and vector PDF files I have and all watermark just fine. It just seems to be an issue with the PDF files generated by Tableau. Anyone have any ideas or workarounds?
