How can I add a signature to each page of a multi-page pdf using Acrobat DC Standard?

[nathanr83281382]

I work in an engineering firm.  We produce technical drawings which we save in pdf form.  These drawings are authenticated, stamped and signed by professional engineers.  Each sheet of the drawing set needs to display a signed and dated stamp.  Sometimes these drawing sets can be hundreds of pages long.  We'd like to add these stamps and signatures digitally and securely to the same location on each sheet.

I'd like to use the "sign" feature but it doesn't have a lot of options.  My only other thought is that I could possibly create a custom watermark that can be added to the whole document but that seems less secure.

We would also be open to purchasing some sort of add-on if there was a more custom solution.

A digital signature applies to the entire file as a whole. There's no reason to sign each page separately.

If you must do it, and still want to use real digital signatures (which, as you mentioned, are secure, as opposed to "wet" signatures which are just comments), then you need to do it on each page, manually. It will also balloon your file-size, as each signature maintains a copy of the original file for verification purposes.

Fair enough try67, that may well be the case in most digitally signed documents but in my industry each page of the drawing must display an engineer's signed stamp.  I guess I'm forced to use the custom watermark option then and then use the "protect" options to make the file secure?

Yes, that's an option... Or use a "wet" signature on the pages (those can

be relatively easily duplicated using a script, by the way) and then sign

it with an actual digital signature once. That's even more secure than

applying a security policy to the file.

Hi Nathan, you could add a watermark to each page and then add a digital signature at the end of your authentication workflow. That is likely the best option with Adobe. However, for batch stamping and signing, there are other tools that can also be helpful. One is a desktop solution called ConsignO that can batch apply templates of 'stamping' zones and batch apply a secure digital signature to protect the integrity of the file and confirm identity of engineer (without the application of password protection). It is used by thousands of engineers in North America that had the same challenge regarding stamping and sealing. It even takes into account date format and position if you need to apply the date on a very specific area of your seal. It would meet your need to batch automate the bulk of your drawing authentication. I have seen the software batch sign with a secure digital signature 1000 documents in less than 15 minutes. Life changer for anyone who signs and seals any amount of drawings.
