We have been pitching a large corporate client on our marketing services for a while now, and and after putting a ton of time into a killer Powerpoint deck, they suddenly want to disseminate it to their staff before signing our contract. I’m not too sure about this, and am thinking that instead of just sending them the preso we could send them a secure PDF, ideally one that would prohibit them copying any data out or printing the content. Is that doable, and if so, how do we get our iMac to do it?
