Using iText, I am creating a PDF document from a series of TIFF images. 

Then (next pass), I am digitally signing it, using an invisible signature.

 

However, I place my invisible signature on page 1 of the document, using

   sap.setVisibleSignature(new Rectangle(0,0,0,0), 1, fieldName);

 

When printing such document from Adobe Reader 7, all pages following the
page 1 (with my invisible signature) are "printed" using some bogus scaling
(i.e. 200 times bigger, rotated 180 degrees) - despite showing 'right' in
the reader.

The problem does not happen with Reader 8.1, and I found only one 'other'
complaint about this kind of a problem on the web (suggested workaround:
remove the signature).

A simple workaround is printing pages in reverse order... but how do I tell
the customer?

 

I tried several things, such as resetting the clip box on each page, or
saving/restoring pdfStamper byte contents before/after preClose(), but none
of that worked.

 

So my current workaround is placing my invisible signature on the _last_
page of the document. This, of course, results in a screwed up print when
someone decides to print pages in the reverse order.

 

Is there some better approach to fixing this (probably Adobe Reader 7 bug)?
