I'll assume you want to use Applescript to customize the workflow and are already familiar with it.
That said, Acrobat provides very little in the way of Applescript access to its core functions. It does provide you access to the UI though, so you can write scripts to click on things in the interface.
A good place to start would be the scripts posted here:
I recommend reading the entire article, but essentially, for Acrobat X, the
OCR This (Acrobat).scpt works as an OS X Folder Action. For each file added to the folder, it will open it in Acrobat and call a custom Action called "OCR This".
If the action "OCR This" does not exist, it will create it. So, you can just rename your action to "OCR This" and use the script as is. However, it shouldn't be too hard, if you're familiar with Applescript, for you to customize it to run your own action.
You'll want to remove any calls to the
setUpAction handler first. Set up and name your custom action manually in Acrobat. Aside from that it should be as simple as replacing any instances of "OCR This" in the script with "Your Action Name".
Good luck, and keep in mind that this is a UI scripting solution. So, if you have a scanner where you can press a button on it to auto scan to the folder, or have a continuous feed, rather than interacting with your Mac, things will run much more smoothly.
