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, Part 3.
The main task of technical committees is to prepare International Standards. 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 14648 may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 14648-1 was prepared by Technical Committee ISO/TC 171, Document imaging applications, Subcommittee
SC 1, Quality.
ISO 14648 consists of the following parts, under the general title Micrographics — Quality control of COM recorders
that generate images using a single internal display system:
— Part 1: Characteristics of the software test target
— Part 2: Method of use
Introduction
This part of ISO 14648 provides a specification for characteristics of a software test target used for the image
quality evaluation of Computer Output Microfilm (COM) recorder systems that generate images using a single
internal display system.

Micrographics — Quality control of COM recorders that generate
images using a single internal display system —
Part 1:
Characteristics of the software test target
1 Scope
This part of ISO 14648 specifies the characteristics of a software test target that is electronically generated, to be
used in COM recorder systems that can accept electronic forms. The components have been designed to check or
test certain capabilities of the COM recorder system in order to enable image quality to be assessed and
maintained. The recording method (i.e. laser scanner, cathode ray tube, light emitting diode, etc.) is not relevant in
establishing the software test target components.
2 Normative references
The following normative documents contain provisions which, through reference in this text, constitute provisions of
this part of ISO 14648. For dated references, subsequent amendments to, or revisions of, any of these publications
do not apply. However, parties to agreements based on this part of ISO 14648 are encouraged to investigate the
possibility of applying the most recent editions of the normative documents indicated below. For undated
references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain
registers of currently valid International Standards.

smallest unit that can be recorded on microfilm by the COM recorder system
4 Test targets
4.1 General
Two test targets are specified. Target 1 (see Figure 2) is intended for COM systems that have limited bit map
memory. The complexity and number of components on the test target are limited to a few basic types.
For COM systems having greater bit map memory capability, Target 2 (see Figure 3) has more components with
increased complexity.
4.2 Dot spacing
The centre to centre spacing of consecutive dots is related to the resolution specification of the orig
