BallotProof: Off-Press QA Scanner for Code-Bearing Ballots
A print-line quality-control scanner that inspects every end-to-end verifiable ballot as it comes off the press — confirming invisible-ink codes are present and machine-readable and serial numbers are unique — so printer failures are caught before ballots reach voters.
Concept
E2E ballots are among the hardest election documents to print correctly: beside the usual candidate text they carry invisible-ink confirmation-code regions that must develop on cue, stay hidden until marked, and still scan cleanly afterward, plus unique serial numbers that anchor the whole cryptographic audit. The Takoma Park case study reports that unreliable ballot printers were a real glitch source in the first binding E2E election, and its limitation list explicitly calls for "improved image analysis for unreadable ballots."
BallotProof is a quality-control station for the ballot production line: a commodity high-resolution scanner plus image-analysis software. As ballots come off the press (or are received at the election warehouse), each sheet is scanned under controlled lighting and the software verifies (1) that every code region contains a well-formed, legible code, (2) that codes remain unreadable under normal lighting, i.e., the invisible ink has not leaked, (3) that serial numbers are unique and match the signed print manifest, and (4) that alignment tolerances for machine scanning are met. Failures are pulled before distribution, and the station emits a signed per-batch QA report the jurisdiction can publish as chain-of-custody evidence. The same image-analysis module can be licensed for election night: Takoma Park already ran its count on parallel conventional desktop scanners with any-which-way scanning, so the reader that certifies ballots off-press can also rescue marginal marked ballots at the count.
Why now
Paper [0] shows the field configuration is proven and deliberately low-cost — the ballots of 1,728 voters across six wards were processed on parallel ordinary desktop scanners, with a full hand recount confirming the outcome — so a dedicated print-QA product is an engineering step from a demonstrated setup, not a research leap. The paper's own limitations name unreliable ballot printers first and explicitly request better image analysis for unreadable ballots. And the demand is not hypothetical: real-world ballot-printing failures such as Maricopa County's 2022 election-day printer problems, which produced unreadable ballots and hours of disruption, show what an unverified print run costs a jurisdiction.

AI assessment
A highly focused, pragmatic QA tool that solves a documented failure point in E2E voting systems using existing hardware and a clear commercial wedge.
- Evidence strength 5/5
- The idea directly addresses the 'unreliable ballot printers' limitation explicitly cited in the Takoma Park case study and leverages the paper's proven use of desktop scanners.
- Market pull 4/5
- High-stakes election environments have a strong incentive to avoid the public relations and legal disasters associated with unreadable ballots, as seen in the Maricopa County example.
- Novelty & moat 4/5
- While CodeSnap focuses on the voter-end capture, this is a distinct B2B supply-chain solution for the printing phase, filling a gap in the E2E ecosystem.
- Feasibility 5/5
- The system uses commodity high-resolution scanners and standard image analysis (OCR/pattern matching), making a prototype highly achievable for a small team.
- Wedge clarity 5/5
- The first use case is a sharp, single-purpose QA station for print-line verification, avoiding the 'platform' trap.
- Simplicity / focus 5/5
- The product is a single, well-defined tool with one clear function: verifying ballot print quality before distribution.

Who benefits
- Runbeck Election Servicescompany
One of the largest U.S. ballot printers; automated per-ballot verification of code-bearing stock protects it from the exact printer-failure mode documented in the first E2E election and gives it a signed QA deliverable for customers.
- Maricopa County Elections Departmentorganization
Its 2022 election-day ballot-printer failures produced unreadable ballots and public disruption; a signed pre-distribution QA report is both direct insurance and publishable evidence that ballots were verified readable.
Supplies ballots and scanners nationwide; a print-line QA station with a signed batch report differentiates its offering to counties considering verifiable or code-bearing ballot formats.
Runs one of the largest ballot production and printing operations in the U.S. through its VSAP program; automated code and serial verification is the only practical way to QA at that volume.
