And you've just added to it. You do realize that ballots are printed by printing companies using offset printing presses, not laser copiers?
But where are the fake ones printed? If what both of you say is true, then ANY ballot with a printer ID mark on it would be fake, yes?
Yes, but late night fake ballots are not.
I voted in advance.
My ballot was printed on the spot.
For mass mailings of ballots, commercial printing might be used.
In 3rd-world countries, you would be correct about offset printing. But in the US:
Top 2 images: HP commercial inkjet printer, capable of 20,000 ballots/hour.
Bottom image: Onsite, on-demand absentee ballot printer for precincts who can afford it ($20,000 for the little one; use your imagination for the HP).
I seriously doubt that such printers are exempted from federal law governing "watermarks" (a misnomer) on prints produced by such equipment.
I used to work at a telephone company as a "Systems Specialist" (equivalent to a senior Systems Analyst) where part of my job involved modifying the font on a high speed laser printer which printed out thousands of bills every day.
The paper used came in extremely large rolls which were fed into the printer intact.
The printer I worked on was much larger than the one showed at the following link and it also included separating each bill and inserting it into envelopes which it also printed.
