Abstract

PROBLEM TO BE SOLVED: To give a metal mask an external elastic force and enable attachment to perform in a short period of time by providing a metal mask retaining piece on each side of a rectangular form plate frame, and thus retaining a printing pattern forming metal mask having bending work attachment parts. SOLUTION: A metal mask retaining piece 4 is secured on each side of a rectangular form plate frame 2, and each retaining piece 4 retains a metal mask 3 detachably to be always pressed outward. The metal mask 3 has square planed and bent attachment parts 6 and printing pattern 8 formed therein. The metal mask retaining piece 4 has a pair of rotatable and slidable rotation plates 12 on the upper surface of each frame 2 side and a pressing rod 14 at the tip end of the rotation plate. The mask 3 used for printing is set on the frame 2 to be positioned inside of the attachment part of the mask 3 through respective rotation of the pressing rod 14 of the retaining piece 4. After that, the mask 3 is pressed outward by the pressing rod 14.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a metal mask printing plate used for printing with high dimensional accuracy and a thamel mask on which a printing pattern is formed.

[0002]

2. Description of the Related Art In a conventional metal printing plate, since a metal mask has no elasticity, a screen printing plate body having a printing plate frame and a gauze attached thereto is used to form a metal mask in which a printing pattern is formed substantially at the center of the gauze. Is fixed by an adhesive, and thereafter, the gauze at the metal mask portion is removed, a photosensitive emulsion is applied to the gauze on the outer peripheral portion of the metal mask and exposed, and the gauze is filled in the gauze.

[0003]

The conventional metal printing plate has the drawback that the work of mounting the metal mask on the printing plate frame is troublesome, time-consuming and costly, and the metal mask is mounted on the printing plate frame. In this state, the metal plate must be transported from the maker to the printing maker, which requires a lot of trouble in the transportation work and increases the transportation cost.

The present invention has been made in view of the above-mentioned conventional drawbacks,
By simply attaching the metal mask to the printing plate frame, the metal mask can be easily and quickly installed with elasticity applied, and only the metal mask can be transported to the printing maker. It is an object of the present invention to provide a metal printing plate that can be easily transported and can be performed at low cost.

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

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a printing frame having a rectangular frame shape, and the four sides of the printing plate frame are cranked or angled so as to have a slight clearance with the inner surface of the printing plate frame. A metal mask on which a printing pattern having a mounting portion bent into a shape is formed, and a metal for holding the mounting portion of each side of the metal mask mounted on each side of the printing plate frame so as to press outward. A metal mask printing plate is constituted by the mask holder.

The present invention also provides a flat rectangular metal mask body on which a printing pattern is formed, and a crank-shaped or angle-shaped mounting part integrally formed with each side of the metal mask body. Constitutes a metal mask.
