I've created a form in a PDF with Adobe Acrobat Pro. When empy, I want to use it as a template which the user opens, fills in, and saves as a copy to preserve the blank state of the template.

Here's the trick : I found both ways to

• make the document read only - the user can't save the form value, only print them
• make the document writeable, but in this case the document acting as a template can be modified too.

Any ideas? Thanks.
