I have received a pdf form that allows for entries to be made. I filled it out and need to forward this in such a way that no more changes can be made to it. The term is 'flattened', as far as I have understood. How do I flatten a file? Is Adobe 9 good enough or do I need a later version?
If you have Adobe Acrobat 9 installed you can use the PDF Optimizer feature (found under the Advanced > PDF Optimizer menu item) to flatten the form fields. Click the following link to view the help documentation for the feature.
