Digital Signature Not Showing Up in Saved PDF

I am frequently sent pdf contracts that need to be filled out, signed and returned. I turn the pdf into a form and then add a signature field, click "certify with visible signature," sign it and save it as a pdf. But then when I email the signed pdf it has all the form content but doesn't show the signature. Same for when I open the file in Preview. The signature only shows up in Acrobat. Can anyone help explain what I am doing wrong?

Thanks in advance.

I found a work-around using Preview on Mac. After adding my signature, I used the Print function and then select PDF, save the file. My signature appeared in the saved version.

I use Adobe Sign to get signatures. Using Windows 10. I then download the signed contracts and save as an unsecured PDF to send to my accounting dept who of course uses MACs. They try to view in MAC Preview. Up until 2-3 weeks ago there was no issue. Now they open my PDF in MAC Preview and they can see the first few pages and the rest are there but appear blank. There was no issue with this for just over 2 years. This issue started 2-3 weeks ago. Supports answer if for them to download and use Adobe Reader DC. Not going to happen. Anyone know of a work around or if I am doing something wrong.

For what it is worth, the same thing happens intermittently using the custom stamp in Adobe Acrobat Pro. It seems assigning blame to other operating systems and programs is irrelevant. A simple "flatten" command would be useful.

Hi,

I am trying to EXTRACT from a PDF with a Topaz signature on it (RUNNING ACROBAT PRO X ON WINDOWS) and when it EXTRACT'S the signature that a client has signed digitally via Topaz it does not show up when saving it, any suggestions?

I am lost and any help would greatly be appreciated.

Hi Arevalo,

When you extract a page (or any mount of pages in the document) you are creating a new document, and thus the signature is always removed. If you want the new document to be signed you need to sign it, you just can't pull pages out and expected the signature to persist.

Hi Steve,

I found a work around it. Extract which pops open a new window THEN sign and then save, which captures the original signature.

Hi,

The problem is Preview (and I assume you are referring to the application that comes on the Mac) doesn't know how to process the signature, so it doesn't display it. However, if your clients use the free Adobe Reader they will see the certifying signature. If you need them to fill out the form, be sure to Reader Enable the file before you send it to them. You can do this by selecting the Advanced > Extend Features in Adobe Reader menu item.

I am referring to the Mac application and your diagnosis makes sense, but

this seriously limits the functionality of the digital signature. The

document (which should appear as a filled out and signed form i.e. a W-2

when I'm done with it) will appear unsigned when opened in a browser, or in

Preview or many other common methods of opening a .pdf. I suppose I could

save it as .tif, then resave it as a pdf, but that's a minor hassle and some

text degradation occurs.

I don't know why you are complaining about what other applications cannot do on an Acrobat forum. Acrobat and Reader process the custom signature appearance just fine and you can even print the file and get the signature to display on the prited page. If you are not happy with what Preview does or doesn't do it would behoove you to take it up with Apple. Meanwhile, the free Adobe Reader will handle the custom signature appearance, and if you can get someone to convert a scanned signature to PDF (that's one thing Reader won't do) you can even use Reader to sign with a custom appearance (provided the PDF file is Reader Enabled).

Steve, are all Adobe employees this argumentative and/or obtuse? There's no complaint in my response to you about Preview or any other application. My response merely pointed out that the wet ink version does not appear in applications outside of Adobe's. "Best of both worlds" in your response is easily construed to mean digital signature ("cryptographically secured") in Acrobat/Reader and "wet ink signature" in other applications. If that's not what you meant, then it's my mistake -- and others will make it, too.

Two additional points:

I understand why Adobe won't (if that's the case) license the digital signatures ability so that Preview and other applications can use it. However, it should be trivial to allow that wet ink signature appear in other apps and I don't see a compelling reason to prevent it -- afer all, it's not a digital signature.
If your job is to monitor this forum and assist users, why couldn't you manage to suggest that the other users use the stamps feature, since it was clear that what they were wanting was only the signature image? These folks are spending hundreds and thousands of dollars on your products and they deserve better than this.
