There was a lot of reporting on these companies in the summer and into fall, easily discovered on the internet (I did that several weeks ago).
One company in Arizona handles the balloting production and mailing for multiple states and has openly stated that it sent more than 50 million ballots for this election (it might have been 80 million, don't recall exact number).
States do not individually have any capability to produce, label, and mail ballots to their citizens. It's all contracted.
DHS was purportedly involved in "ballot security" with these companies, but has declined to comment on what measures might have been taken. And some states require (or prohibit) watermarking by statute.
I would not be surprised if blue states prohibited watermarking and red states required water marking. Things that makes voting more secure seems to be done in red states and things that make cheating easier seem to be done in blue states.
