Question
How best to protect a stamped drawing
I am an engineer who produces stamped documents and drawings in pdf format. I need to ensure that the file cannot be changed after I stamp it, but I also need to allow anyone to view and print the stamped document at any time. I cannot use a distribution list as I have no way of knowing where my clients will choose to print their drawings.
What is the best way to accomplish what I need?
Thanks for your help.
