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.

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

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

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
