For now I have one issue with PNG graphics with transparency: For example I include http://upload.wikimedia.org/wikipedia/c ... en.svg.png in a MS Word 2007 document. I create PDF files with PDF-XChange printer driver and with Acrobat 8 printer driver.
Both files look OK in both viewers, but when I print this PDFs from PDF-XChange Viewer, the picture has a black background overlaying title and labels. It is worse with the PDF created by Acrobat, where the printout is somehow scrambled. Acrobat 8 and Acrobat Reader X printouts are fine.
We have used this graphic in a PowerPoint presentation. When I create a PDF from this presentation with PDF-XChange printer driver, the same effect (black background) also happens when printing with Acrobat Reader X.
Is this a bug or can I do something about this (assuming the original document is given and can't be changed)?
