Security

Where ballots are liable materials, the following security measures should be applied during printing.

• an undertaking by the contractor regarding security of ballot materials;

• secure, weatherproof storage by the print contractor of all printed ballots, ballot paper stock, printing plates and other ballot reproduction material;

• physical security in the printing plant, including searches of employees leaving the premises;

• secure return of all printing plates and reproduction material to the electoral management body for secure destruction at the conclusion of prints run.

Where special paper stock is used as an integrity control, security would also be required, including:

• secure storage of ballot paper stock on the print contractor's premises;

• contractor's accounting for and secure destruction of all off-cut and waste paper stock and printing spoils;

• contractor’s accounting for all paper stock supplied but not used.

More Americans than ever before are expected to vote by mail this year because of concerns about the coronavirus. One challenge facing election officials now: how to print and mail the millions of ballots voters are expected to request in the coming months.

Nearly a quarter of the 136 million presidential ballots cast 2016 were mailed in. That number could easily grow to well over half this year, especially if the health risk continues.

With many states expected to expand mail-in voting for November, experts warn that existing ballot printing services could quickly become overwhelmed.

One of of the biggest such vendors in the country is Runbeck Election Services. The company's 90,000-square-foot facility in Phoenix, Ariz., is already bustling, and things are expected to get a lot busier soon.
