Auto-Save to PDF not saving floating signature block to pdf output

I have a routine set up which takes a PDF document, affixes an electronic stamp on the document and uses PDF creator to save the document as a new PDF.  I am having an issue with certain documents which contain a floating signature block that someone affixed to the original PDF (an image of their signature). When I apply my stamp and use PDF Creator to create a stamped version of the document the signature block is no longer there.  Any suggestions how to get the signature block to be included with the final output?

Nevermind, the issue seems to be with Adobe Reader not outputting the signature block to PDF Creator.
