You can install PDFtk (
https://www.pdflabs.com/tools/pdftk-server/) on your server, and use the following command, with run command app :
Code: Select all
pdftk.exe "%%InputFilePath%%" output "[Job.NameProper].pdf" owner_pw "1512!" user_pw "1234" allow Printing
Here is a quote from the documentation, for the permission
[ allow < permissions > ]
Permissions are applied to the output PDF only if an encryption strength is specified or an owner or user password is given. If permissions are not specified, they default to ’none,’ which means all of the following features are disabled.
The permissions section can include one or more of the following features:
Printing – Top Quality Printing
DegradedPrinting – Lower Quality Printing
ModifyContents – Also allows Assembly
Assembly
CopyContents – Also allows ScreenReaders
ScreenReaders
ModifyAnnotations – Also allows FillIn
FillIn
AllFeatures – Allows the user to perform all of the above, and top quality printing.

I would have preferred to use Pitstop (if the function existed) or an application from the appstore.

As an alternative to a PitStop action list, you could do this directly with Acrobat's own Action Wizard tool and a custom Acrobat action. The screenshot shows how.

Hi there,
A feature you can use is actually Certified PDF. if you certify the PDF, you at least "freeze" the PDF in a certain state. If the document is further modified, the certification will drop. And if recertified, you will have access to History about who dit it and when.
Icing on the cake, you can revert to the previous certified state.
This is not locking per say, but I think Certified PDFs are underestimated.
