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

Introduction

This document stipulates dimensional properties of printing plates for offset printing. While not all

present plate dimensions will conform to this document, the specifications for dimensions serve as an

effort to reduce the multitude of possible formats to a reasonable level that simplifies manufacture and

communications between plate, platesetter and press manufacturers, and the printer.

In this revision, preferred plate sizes are introduced. These represent the most widely used plate sizes

and should be selected where possible. It is recognised that for some printing work, other sizes are

required.

4 Requirements
4.1 Measurement conditions

Measurements shall be conducted when both measurement equipment and plates have reached a

stabilized temperature of 21 °C ± 1 °C.
4.2 Plate dimensions

Commonly used plate widths and heights identified by plate and press manufacturers are specified in

Annex D. When selecting plate width and height, these preferred plate sizes should be used.

Where these plate sizes cannot be used, plates for sheet-fed lithographic use may be of any length, L, or

width, W, but shall be specified in multiples of 5 mm where the last whole number digit is 0 or 5. Plates

for web lithographic use may be of any length or width but shall have their width specified in multiples

of 5 mm where the last whole number digit is 0 or 5 and their length specified in multiples of 2 mm

where the last whole number digit is 0, 2, 4, 6 or 8. These requirements are summarized in Table 1.

Except where preferred plate sizes are being used, the tolerances for length and width shall be as shown

in Table 1, the measurement conditions of 4.1 shall apply.
The preferred thicknesses and their tolerances shall be as shown in Table 2.
