I've got an interactive PDF document that was created using Adobe Indesign CC. I'm trying to save the document as a PDF/E file, but when I perform the preflight from Adobe Acrobat, It says "Signature field present but no SigFlags entry in the interactive forms dictionary".
I'm not sure how I would fix this. Is it a matter of adding a signature flag somewhere? If so how is that done?
Any help would be very much appreciated.
Here is a screenshot of the error:
When you add a digital signature field using Acrobat it should have added a SigFlags entry. Did you use Acrobat to add digital signature fields or digitally sign the document?
Hi George, Thank you. No I haven't added any signature fields or digitally signed the document. it just contains text boxes and a submit button.
Random guess: I wonder if it was Reader Enabled?
