Benefits of technology

The technical effect described by this patented technology allows for accurate measurement of how strong each area of the image being printed has been exposed during shipping or storage without causing any harm if it were meant to break off from its original design. This helps ensure reliable protection against damage caused by external factors such as impacts or vibrations.

Problems solved by technology

This patent describes how conventional techniques for creating lamination structures involve cutting up individual sheets of photography films before applying another piece onto top of them together. These steps require manual labor and may result in errors due to differences in image quality caused during production. Additionally, current solutions involving multiple tools increase costs compared to single tool systems.

Embodiment Construction

[0048] Description of the preferred embodiment

[0049] figure 1 A packing member 20 of the planographic printing plate 10 according to the first embodiment of the present invention is shown. The lithographic printing plates 10 are stacked into a stack 12 and the stack 12 is packaged in a packaging box 22 . Figure 3A and 3B represents a method of the present invention for measuring the imaged surface strength of a lithographic printing plate (hereinafter referred to as "method").

[0050] The lithographic printing plate 10 is formed by affixing a film (a photosensitive layer in the case of a photosensitive printing plate, a heat sensitive layer in the case of a thermal printing plate) to a thin rectangular aluminum support. Then, the lithographic printing plate is subjected to plate-making steps such as exposing, developing, gumming or the like, and the lithographic printing plate is loaded into a printer and ink is applied to print characters, images or the like on paper.

Abstract

A method for measuring strength of an image forming surface of a planographic printing plate. In this method, an image forming surface of a planographic printing plate is contacted with a non-image forming surface of another planographic printing plate, a weight of predetermined mass is placed thereon, and the planographic printing plates are slid against each other in a direction along the image forming surface. A maximum value of pressure that does not generate damage when applied to the image forming surface of the lower planographic printing plate is used as strength of the image forming surface. By stacking and packaging planographic printing plates having an image forming surface strength of no less than a specified value, damage to the image forming surfaces of the planographic printing plates in a packaged state can be prevented.
