Graphic technology — Plates for offset printing — Dimensions
ISO 12635:2008 specifies the width, length and thickness of metal lithographic printing plates (referred to in the document as “plates”). For plates to be used in computer to plate (CtP) applications, flatness, edge straightness and burr requirements are also included. These requirements are applicable to unprocessed plates.

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 2.
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 document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 12635 was prepared by Technical Committee ISO/TC 130, Graphic technology.
This second edition cancels and replaces the first edition (ISO 12635:1996). It has been extensively revised in
all sections; requirements for perforations and designations have been deleted.

Introduction
This International Standard stipulates dimensional properties of printing plates for offset printing. While not all
present plate dimensions will conform to this International Standard, 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, the requirements for perforations and designations have been deleted. According to recent
developments in dimensions of printing plates, especially within the thickness dimension, new thickness
categories have been implemented. Due to the increasing adoption of CtP, additional attributes have been
introduced to be applied to plates with these new devices.

3 Requirements
3.1 Measurement conditions
Measurements shall be conducted when both measurement equipment and plates have reached a stabilized
temperature of 21 °C ± 1 °C.
3.2 Plate dimensions
Plates for sheet-fed lithographic use may be of any length, L, or width, W, but shall be specified in increments
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 increments of 5 mm where the last whole number digit is 0 or 5
and their length specified in increments of 2 mm where the last whole number digit is 0, 2, 4, 6 or 8. These
requirements are summarized in Table 1.
The tolerances for length and width shall be as shown in Table 1, the measurement conditions of 3.1 shall
apply.
