ISO 11928-1:2000 マイクログラフィックス—グラフィックCOMレコーダーの品質管理—パート1：テストフレームの特性 | ページ 2

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.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, 3.

Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.

Attention is drawn to the possibility that some of the elements of this part of ISO 11928 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

International Standard ISO 11928-1 was prepared by Technical Committee ISO/TC 171, Document imaging applications, Subcommittee SC 1, Quality.

ISO 11928 consists of the following parts, under the general title Micrographics — Quality control of graphic COM recorders:

• Part 1: Characteristics of the test frames
• Part 2: Quality criteria and control

Introduction

This part of ISO 11928 has been prepared because increasing numbers of technical drawings are now produced on COM, and, although their quality is usually reasonable, they are not always comparable with microfilm copies of hard copy drawings. This can cause difficulty when both kinds of drawing are put into aperture cards and used in systems designed to deal with microfilm copies of hard-copy-drawings.

This part of ISO 11928 has therefore been prepared to help users to establish procedures that should ensure that the quality of COM-generated drawings is both acceptable in itself and comparable in quality with technical drawings on conventional microfilm that complies with ISO 3272-1, ISO 3272-2 and ISO 3272-3.

1 Scope

This part of ISO 11928 specifies the characteristics of the test frames used for evaluating the image quality of microforms from graphic COM recorders.

It applies to graphic COM recorders that are capable of producing both alphanumeric and graphic images output onto black-and-white films.
