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 8514 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

International Standard ISO 8514-1 was prepared by Technical Committee ISO/TC 171, Document imaging applications, Subcommittee SC 1, Quality.

This second edition cancels and replaces the first edition (ISO 8514-1:1992), which has been technically revised.

ISO 8514 consists of the following parts, under the general title Micrographics — Alphanumeric computer output microforms — Quality control:

• Part 1: Characteristics of the test slide and test data
• Part 2: Method

Introduction

The use of alphanumeric computer output microforms (alphanumeric COM) for the storage of information requires valid, reliable methods by which the quality of the images can be measured. This is necessary to achieve consistent usable output. Of primary importance in the production of microforms containing alphanumeric information is the legibility of the information presented to the user. This is true whether the microform used is the original (first generation) or a duplicate.

ISO 8514 specifies a method for measuring the quality of computer output microforms (COM) and specifies a test form slide and test data to be used for applying this method. It applies to microforms containing variable data produced using a cathode-ray tube, light-emitting diodes or a laser, and fixed data such as that contained on a form slide, with effective reduction ratios of 1:24 through 1:48, in accordance with ISO 9923. This International Standard applies only to COM recorders that use a physical form slide.

This International Standard describes various systems and equipment to establish test guidelines whereby the user can establish and maintain a given level of performance using the minimum of sophisticated equipment.

The method requires a test form slide and test data generated from the COM image generator.

1 Scope

This part of ISO 8514 specifies the characteristics of the test slide and the test data used for measuring the output quality of alphanumeric COM recorders that use a physical form slide.
