This document replaces GB/T 17155-1997 "Offset Printing Plate Dimensions". Compared with GB/T 17155-1997, except for structural adjustment and editing
In addition to editorial changes, the main technical changes are as follows.
a) Add terms and definitions such as cutting burr, edge waviness, edge straightness, and printing plate base (see 3.1, 3.4, 3.5, 3.6);
b) Deleted the term and definition of plate length (see 2.2 of the.1997 edition);
c) Changed the printing plate size requirements (see 4.2, 3.2.1 of the.1997 edition);
d) Delete the eyelet requirement (see 3.2.2 of the.1997 edition);
e) Requirements for rectangularity, CTP edge waviness, CTP printing plate cutting burr, and CTP edge straightness are added (see
4.3, 4.4, 4.5, 4.6);
f) The nomenclature and marks are deleted (see Chapter 4 and Chapter 5 of the.1997 edition);
g) Deleted the standard measurement environment (see Appendix A of the.1997 edition).

Introduction
This document specifies the dimensional characteristics of printing plates for offset printing. While not all existing plate sizes conform to this document, the size specifications are intended to
In reducing the number of possible specifications to a reasonable level, thereby simplifying the manufacturing process, and facilitating printing plate, plate making machine and printing press manufacturers and printing presses.
Brush the exchange between enterprises.
In this revision, preferred plate sizes were introduced. Whenever possible, these were chosen to represent the most widely used plate sizes. well known
It is known that other sizes are also required for some printing jobs.
Offset printing plate size
1 Scope
This document specifies the width, length and thickness of metal lithographic printing plates (hereinafter referred to as "plates"). For computer-to-plate
Plates used in (CTP) also specify flatness, edge straightness and burr requirements. These requirements also apply to printing plate bases.
2 Normative references
This document has no normative references.
3 Terms and Definitions
The following terms and definitions apply to this document.
3.1
cutting burr cuttingburr
A protrusion formed by cutting, especially with a dull knife, along the edge of a printing plate.
3.2
Plate width platewidth
The size of the printing plate parallel to the axial direction of the cylinder (plate clamping edge).
3.3
Plate thickness platethickness
Plate thickness after coating.
3.4
edge waviness
The degree to which the edge of the printing plate conforms to the plane of measurement.
3.5
Draw a straight line parallel to the axial direction of the cylinder (plate clamping edge) from the corner of the printing plate, the maximum deviation of the straight line from the edge of the printing plate.
3.6
Printing plates based on unprocessedplates
Plates from the manufacturer.
4 requirements
4.1 Measurement conditions
The measurement shall be carried out when both the measuring instrument and the printing plate have reached a stable temperature of 21°C ± 1°C.
