LOCKING A PDF PRESENTATION

If you're using Photoshop to create a PDF Presentation slide show (under the File Browser's Automate menu) so you can e-mail it to your clients for proofing, one of your concerns may be that your client will just print your photos out to a photo-quality printer, leaving you out in the cold (so to speak). But you can pull the plug on their printing aspirations. When saving your PDF Presentation, under Output Options, choose Presentation, then hit Save. It'll ask you to name your PDF presentation (you're not done yet), so name it and click Save. When you name it and click Save, a PDF Options dialog will appear. Click on the PDF Security checkbox, then click on the Security Settings button. In the PDF Security dialog, click on the checkbox for Password Required to Change Permission and Passwords and enter (and memorize) a password. Then, under Compatibility, turn on the checkboxes for No Printing, No Changing the Document, and No Content Copying or Extraction, Disable Accessibility. Click OK and it'll ask for your password one more time. Now, when you e-mail the PDF Presentation, printing will be grayed out, and even if they have the full version of Acrobat, they won't be able to copy and paste your photos into something else for printing.
