Watermark in Word files -> PDFCreator -> iPad

When creating a PDF file from a Word document, which contains a watermark, and viewing this file on an iPad the whole document appears empty.

Checked with version 1.1 and 1.2.

With other PDF print tools, like CutePDF creator, there is no such problem.

Is there a way this could be fixed with an 'before saving' script or in and upcoming version?
