Image pasting into a PDF doc in Reader and preserving transparency?

Hi

I successfully created an image of a signature with a transparent background: file format = PNG file.

Ultimately, I need the signature pasted into an Adobe Reader File and not Acrobat.

So far, I've selected and copied the PDF page as an image into Word. Then I copied and pasted the signature PNG file into the WORD file. So far it looks fine.

All I want to do next is save or print this WORD into a new PDF (with newlt pasted, transparent signature). As soon as I try printing with WORD's PDFcamp printer option, it opens my file, with the signature into a new PDF document, BUT the signature now has that dreaded white box or background around it.

Is it possible in Reader, not having the full version Acrobat, to do what I am trying?

Thanks for your help!

Mike
