The ONLY way to do this is to use cryptography, or very expensive
printing processes.
Any high quality copier will be able to make duplicate copies of any
ballot we print on a laser
printer which will be essentially indistinguishable from the
original. The flag may make
the printed ballot look patriotic, but it will not prevent counterfeiting.

That's assuming you use plain old paper. If you want to create
individually numbered and water
marked paper ahead of time ( using special printing presses etc ),
and then run these through the
plain old laser printer, that might work.
