We provide 3D kitchen designs in the form of PDFs
We would like to be able to protect them from being printed, screenshot if possible.
We would also like to be able to send them with a 'self destruct' built in after a certain time limit. Unknowns to the customer.
Is this possible?
Thanks in advance,

To prevent printing, restrict it in the PDF's security settings.
You'll need to save the document in order for the settings to "take."
The "self-destruct" will have to be custom coded. Maybe one of our script gurus will chime in on this. If they do, you'll have the advice from some of the best coders in the world.
Preventing taking screenshots is impossible.
"Self-destruct" is only possible in Mission Impossible movies... In the real world the closest you can get is to protect the file with DRM technology which will prevent it from being opened after a certain time. This kind of protection costs a lot of money to apply, though.
I think 'self destruct' was more of a way of saying that the link to that design that we send would have a life span that we control automatically.
We know we can switch off the link manually but it would be good to be able to send the design out and after say 7 days the link expired.
Apologies for dramatising the process.
Removing the link will not work. When the user view the PDF file he/she has already a copy of the file.

Please ignore the idea that you can use PDF security settings to prevent printing, this is just ignored by many apps, utterly worthless. If you have the necessary budget (5 figures, maybe 6), skills and resources (24/7 server, customer tech support), you could go down the DRM path.
Can you stop a screen shot? Who cares. Point a camera at the screen. People do it all the time.
I am very concerned at what you seem to propose, that what you sell would stop working WITHOUT THE CUSTOMER BEING TOLD. This would open you to legal action. You must be open about selling time-limited info.
Essentially though, welcome to the world of online selling where nothing can effectively be protected, whatever your budget.
This kind of thing is always a question of balancing effort and expense v. security and reliability.
You can spend a lot of money on DRM protection and it will work very well.
Or you can spend a medium amount of effort and resources and protect the file relatively well, meaning a willing-enough user will still be able to work around your protection, and it might not work in all circumstances, but it will work some of the time and might deter 80% of people from trying to get around it.
Or you can spend very little effort and just accept this loss as a part of business. And if it's taking you 3 days to set up these designs then maybe you should charge your clients for that work, too... You can deduct it from the final price if they decide to go through with it finally.
An example of a "middle of the way"-type security is a script that can be embedded into the file that will check the current date and if it's past some pre-defined value will automatically close the file.
So the question is whether or not it's worth the effort of implementing it at all.
I can develop it for you, if you wish, for a small fee.
You can contact me privately via [try6767 at gmail.com] to discuss it further.
