Full title and description

Information technology — Automatic identification and data capture techniques — Optical Character Recognition (OCR) quality testing. This International Standard specifies methods for measuring attributes of OCR-B character strings, evaluating those measurements to derive an overall quality assessment, and includes a reference decode algorithm and guidance on causes of degraded quality and corrective actions.

Abstract

ISO/IEC 30116:2016 defines a methodology to measure specific attributes of OCR-B printed character strings, a method to evaluate those measurements into an overall grade, and a reference decode algorithm for OCR-B. The standard is intended primarily for OCR-B as defined in ISO 1073‑2 but its methodology can be applied, in whole or in part, to other OCR fonts.

• Edition / version: Edition 1, 2016 (ISO/IEC 30116:2016).
• Number of pages: 29 pages (official ISO summary lists 29 pages).

Scope

Specifies measurement methodology for attributes of OCR-B character strings, provides evaluation criteria to derive an overall quality assessment, defines a reference decode algorithm for OCR-B, and offers guidance on likely causes of deviations from optimum grades to support corrective action. The normative scope is OCR-B (ISO 1073‑2), but the methods may be applied partially or fully to other OCR fonts and implementations.

Key topics and requirements

• Definition of measurable attributes for OCR-B character strings (contrast, spacing, stroke integrity, noise, alignment and similar metrics).
• Procedures to measure those attributes under defined test conditions.
• Rules and formulas to combine individual measurements into an overall quality grade (pass/fail or graded assessment).
• Reference decode algorithm for OCR-B to provide a benchmark for interoperability and repeatability of tests.
• Guidance on typical causes of degraded OCR quality (printing, substrate, imaging, environmental, and device-related issues) and suggested corrective actions.

Typical use and users

Used by test laboratories, manufacturers of OCR readers and printers, quality assurance teams for identity documents and machine-readable documents, governments and agencies issuing machine-readable travel or ID documents, and integrators evaluating OCR performance on documents and labels. Typical applications include document issuance, banking and financial document processing, barcode/label human-readable interpretation, and any environment where OCR-B readability must be quantified and validated.

Related standards

ISO/IEC 30116:2016 is directly related to the OCR character definition standard ISO 1073‑2 (Character set OCR-B — shapes and dimensions of the printed image). It sits within the work of ISO/IEC JTC 1/SC 31 (Automatic identification and data capture techniques) and should be considered alongside other SC31 outputs addressing identification, data capture and machine-readable document specifications.

FAQ

Q: What is this standard?

A: ISO/IEC 30116:2016 is an International Standard that defines methods to measure and evaluate the quality of OCR-B printed character strings, including a reference decode algorithm and guidance on causes of degraded quality.

Q: What does it cover?

A: It covers measurement procedures for specific OCR-B attributes, rules to derive an overall assessment (quality grade), a reference decode algorithm for OCR-B, and explanatory guidance to help diagnose and correct common causes of poor OCR performance. The methodology can be applied to other OCR fonts where relevant.

Q: Who typically uses it?

A: Test laboratories, equipment and software vendors, document-issuing authorities, QA teams, and systems integrators who need a standardized, repeatable way to quantify OCR readability and interoperability.

Q: Is it current or superseded?

A: This is the 2016 edition (Edition 1) and is published and confirmed as the ISO/IEC 30116:2016 International Standard. Users should check with their national standards body or ISO for any subsequent amendments or revisions beyond the 2016 edition.

Q: Is it part of a series?

A: It is part of the body of standards produced under ISO/IEC JTC 1/SC 31 (Automatic identification and data capture techniques) and is directly linked to OCR character-set specifications such as ISO 1073‑2 (OCR‑B). It complements other SC31 work on AIDC and machine-readable document practices.

Q: What are the key keywords?

A: OCR-B, OCR quality testing, reference decode algorithm, AIDC, character-string grading, ISO/IEC 30116, ISO 1073‑2.
