Digital Signature

Dear All,

I am trying to print a certificate issued by Government agency with digital signature on a A4 Pdf.

I see the digital signature is not printing.

Regards

 

Syrus 

I am attaching sample.

Re: Digital Signature

Are you using FFCore? Is this a problem on a printer? If so which one?

Re: Digital Signature

Hi,

I am using the trial version of FreeFlow Core, with Xerox 550 with external Fiery. 

When I use optiomise node in Core with pdf flattening settings, the digital signature is not getting printed.

I am attaching 2 samples, Original.pdf is with digital signature in green tick mark. second file where digital signature is a question mark.

Regards

Syrus.G

Re: Digital Signature

FFCore is able to preserve the "green check" for the digital signature, when the PDF is routed to a Save node. If any content is added (e.g., by the Watermark node) to digital signature verification will fail. When the file is submitted to a Fiery, the "green check" is replaced by a "yellow question mark". Whether the submission is through FFCore or Acrobat, the issue remains.

There may be a way on the Fiery to "confirm" the signature. I recommend contacting Xerox support for your printer to determine if this is possible. If you obtain a method to do this, could you please post this?

Re: Digital Signature

Try the attached preflight profile. It works to flatten annotations and similar items that are not a standard part of pdf files.

Should do the trick - I didnt get to try it with your sample files as they are gone.

I have used the preflight profile given by you, but I could not see the green tickmark on the files when I saved the file.
