Our company has recently been upgrading from Adobe 8 to Adobe X (more specifically 10.1.10.) In Adobe 8 there is an ability to add/subtract pages after a signature has been signed, however this does not work in Adobe X with the default settings and I have not located a way to adjust this. Within the company there is a department in legal/accounting that handles the creation of PDF documents from basically start to finish. During their creation process there needs to be two signature: one for the creator of the document (this field is important enough that I cannot simply copy an ID/key so that anyone can sign anyone’s name however it is not important enough that it needs to lock a document or prevent any changes including adding/subtracting pages.) The creator will start a document sign and then pass it on where it will be modified, pages will be added/subtracted and words may be rearranged. Once it has been revised a couple to even a few time a second signature will lock the document. Is this still possible in Adobe Acrobat X Pro or Standard? Thank you in advance.
