Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).

The committee responsible for this document is ISO/TC 171, Document management applications, Subcommittee SC 1, Quality.

ISO 12653 consists of the following parts, under the general title Electronic imaging — Test target for scanning of office documents:

Part 1: Characteristics
Part 2: Method of use
Part 3: Test target for use in lower resolution applications

Introduction

This part of ISO 12653 describes procedures for evaluating the quality of output from office document scanning systems that are set to scan documents up to 300 dpi. The systems can be used to scan in black and white, in greyscale, or in colour.

Test charts and targets already exist for micrographics and facsimile transmission but they are specific to these said fields and do not meet the needs of the users of document scanning systems.

ISO 12653‑1 specifies a test target for use in general scanning systems, to enable their performance to be evaluated and to establish performance limits of the systems. Its method of use is specified in ISO 12653‑2.

1 Scope

This part of ISO 12653 specifies a test target for assessing the consistency of the output quality over time from lower resolution reflection scanning systems.

It is applicable to assessing the output quality of black-and-white and colour scanners used for black-and-white or colour office documents, with or without half tone.

It does not apply to scanners used for the scanning of transparent or translucent documents.
