For the ultimate in souvenir tickets (non thermal) we designed and created a unique security watermarked threaded paper. This acts like a bank note which is almost impossible to replicate.

Below you can see the watermark and the threads running through the paper.

We print the tickets so that 2 threads are present in each ticket, one running through the stub and one through the main body of the ticket.

This again is a controlled security paper which only exists for us and so not available off the shelf as a bought product.

Below is an enlargement of the actual thread, the words "Veritas" repeat back and white through each thread.

In addition the thread will fluoresce under a UV light and the paper also has invisible UV strands and flecks built into it.
