My understanding is that since 2018, blank ballot paper (watermarked) has been supplied by CISA to the states who then print the ballots.
Does anyone know if this is true?
All the CISA, to my knowledge, has said is that states and voting systems have a variety of techniques at their disposal, including watermarking, specific paper weights, bar coding, etc.
The CISA has never specified, again to my knowledge, who/what uses which.
