[STR Closed w/o Resolution]

Some deeper investigations revealed that the PDF has been created by either
the commercial FineReader application or by a home grown application using
the FineReader's developement kit.

Obviously the scanned images have been OCRed and the recognized text has
been inserted to the pages using a normal TrueType font, "hidden" by the
white background of the scanned images but not set up as "hidden text"
according to the PDF spec.

The blurred rendering could be enhanced by the final PDF renderer if the
white background is treated as a transparent background, so that the
"hidden" text is still visible.
