Description (English):

ISO/IEC 24790:2017 specifies device-independent image quality attributes, measurement methods and analytical procedures to describe the quality of output images from hardcopy devices. This document is applicable to human-readable monochrome documents produced from printers and copiers. The attributes, methods and procedures rely on measurable properties of printed text and graphic images. Special targets or reference images are not required, but image elements are useful for adequate measurements only if they meet some minimal requirements, e.g. on size or number present. This document is not applicable to images on media other than hardcopy (e.g. images on a visual display) or to images that are intended to be machine readable only (e.g. bar codes).

Abstract

Overview

ISO/IEC 24790:2017 defines device‑independent image quality attributes, measurement methods and analytical procedures to describe the quality of hardcopy output for monochrome text and graphic images. The standard is applicable to human‑readable monochrome documents produced by printers and copiers and targets objective, repeatable measurements that correlate with perceived print legibility and appearance. It does not apply to display images or images intended only for machine reading (e.g., barcodes).

Key Topics

Device‑independent attributes: A schema of measurable image quality attributes for both large‑area graphics and character/line images (e.g., darkness, graininess, mottle, blurriness, raggedness, voids, banding).
Measurement methods: Procedures for capturing and quantifying attributes using instrumented measurement systems; emphasis on properties visible at normal viewing distance rather than diagnostic micro‑targets.
Sampling and reporting: Guidance on page/image sampling schemes (random, discretionary, whole‑page), required test identification and how to report results and conformance.
System conformance: Criteria and components for validating measurement instruments and procedures, including OECF conversion and MTF compensation, plus normative test objects and goal values.
Normative annexes: Test bitmaps, chart layouts and conformance test details are provided as annex material to support repeatability.
Scope limitations: Special test targets are not required, but image elements must meet minimal size/quantity requirements for reliable measurement.

Applications

ISO/IEC 24790 is practical for organizations and professionals who need objective, reproducible hardcopy image quality assessment:

Quality control engineers performing acceptance testing and production monitoring of office printers and copiers.
Manufacturers and R&D teams benchmarking device performance, optimizing print processes and validating firmware or hardware changes.
Test laboratories and service providers delivering standardized image quality reports for customers.
Procurement and compliance teams specifying minimum image quality requirements for office fleets and vendor evaluations.
Software/tool vendors developing automated image quality analysis or calibration systems for monochrome output.

Related Standards

Supersedes ISO/IEC TS 24790:2012 and ISO/IEC 13660:2001 (technical revision and consolidation).
Developed by ISO/IEC JTC 1/SC 28 (Office equipment) and intended to be used alongside device‑specific test methods where diagnostic, high‑resolution targets are available.

Keywords: ISO/IEC 24790, image quality measurement, hardcopy output, monochrome text and graphics, printers, copiers, sampling scheme, conformance testing.
