Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal mask and a metal printing plate used for printing with high dimensional accuracy.

[0002]

2. Description of the Related Art In a conventional printing plate, a metal mask has no elasticity, so that a screen printing plate body having a gauze attached to a printing plate frame is used to bond and fix a metal mask to an approximately central portion of the gauze with an adhesive. . After that, after removing the gauze on the metal mask portion, the gauze on the outer peripheral portion of the metal mask is coated with a photosensitive emulsion and exposed to light to form a hole in the gauze.

[0003]

The conventional metal printing plate has a drawback that it takes time and effort to make the metal printing plate and the cost is high. In addition, since the metal mask cannot be used by replacing it, the screen printing plate body that costs 40,000 to 50,000 yen per frame is effective because the metal printing plate body is made by using the screen metal plate itself for the required metal mask. It had the drawback that it could not be used and the equipment cost was high. Further, transportation of the metal printing plate from the metal printing plate manufacturer to the printing manufacturer has to be carried out for each large metal printing plate, which requires a lot of labor for transportation work, resulting in high transportation cost.

In view of the above-mentioned conventional drawbacks, the present invention has been made.
A metal mask and a metal printing plate which can be easily manufactured at a low cost in a short time by imparting elastic force to the metal mask itself, and can be easily processed and manufactured. Is intended to provide.

The above and other objects and novel characteristics of the present invention will become more fully apparent when the following description is read in view of the accompanying drawings. However, the drawings are for explanation only and do not limit the scope of the present invention.

[0006]

In order to achieve the above object, the present invention excludes a metal mask main body whose upper, lower, left and right ends are attached to a printing plate frame, and a printing pattern forming portion in the central portion of the metal mask main body. A metal mask is formed by an elastic force applying portion including a plurality of cutout portions or a plurality of through holes formed so that the elastic force can be applied in at least one of the up-down direction and the left-right direction near the printing plate frame. I am configuring.

The present invention is also directed to a printing plate frame, a mounting tool capable of mounting a metal mask mounted on each piece of the printing plate frame in an outwardly pulled state, and upper, lower, left and right ends of the mounting tool. From a plurality of notches or a plurality of through holes formed so that elastic force can be applied to at least a portion near one end in the up and down direction and a portion near one end in the left and right direction to which the portion is attached. A metal printing plate is configured with a metal mask having an elastic force applying portion.

[0008]

When the metal mask configured as described above is attached to the printing plate frame, the elastic force applying portion is extended by pulling the metal mask in the vertical and horizontal directions, and the metal mask is attached with the elastic force applied. Also, when printed, the elastic force imparting portion expands and contracts, and printing can be performed in the same manner as a conventional screen printing plate using gauze.
