Acrobat 9: Apply Security to PDF v6 without it changing to v7.

[Peter_Lindfield@adobeforums.com]

Adobe Acrobat Pro 9.0.0 (MAC)

Apple Mac Book Pro 17" 2.4Ghz, 4GB RAM.

I am working for a client which is using Adobe Reader 6, but I am using Acrobat 9 Pro. By using the Reduce File Size function and setting it to version 6 and later, I have managed to make the files open in Reader 6 without any warning about the PDF files being made in a later version that that being used to read them.

This works, and there is no version warning, however, when I apply security to all 90 PDFs, which is set to version 6, the PDFs once again give the version compatibility warning.

So, is there a way to apply security to a PDF using Acrobat 9.0.0 and enable it to be opened with reader 6 without version warnings (other than using Acrobat 6, which I do not have)?

Thanks all.

try doing in reverse. apply the security, then reduce file size ver6. see what happens

Excellent - this works. I tried everything else, but not this. I thought that once security was applied I could not perform the operation before saving.

Now before you get your hopes up too high check to see if security is still set. just try one or two. It could be that Security wasn't a feature of Acrobat until 7. If security is still set your all set.

I have checked and the security, as set, remains intact after the reduce file size function.

Under document properties (I am checking every file to make sure) PDF is version 1.5 and security does what I asked it to prevent/allow.

Thanks for your assistance in this matter - a long project full of unexpected twists (like this security biz) is now at its end.

Acrobat actually applies the security once the file is CLOSED

Glad my info helped. Although I misspoke on my last comment when I mention Acro7 when I meant Acro6.
