The present invention relates to a printing mask, and more particularly, to a printing mask having a novel structure, which has a small volume, high space utilization, high strength, and easy handling.

Screen printing or stencil printing is used when printing patterns in the SMT (Surface Mounting Technology) field or in various fields. Screen printing or stencil printing is a printing method of substantially the same technique in that it is printed using a mask.

Fig. 1 shows a printing mask used in such screen printing or stencil printing. As shown in Fig. 1, a screen 4 in which a masking 6 is formed on a non-stripe portion excluding a portion to be printed 2). The screen 4 is made of a cloth or a metal mesh or the like and the masking 6 is attached to the screen 4 with a hole formed in a shape corresponding to the hooking line, ), Or the like.

When printing is performed using such a mask, the ink is stretched on the screen 4 and then squeegeeed. In this process, an external force acts on the screen 4 and the frame 2.

For this reason, unless the strength of the frame is high, the mask 2 is deformed such that it is twisted. Therefore, the frame 2 is usually made to have a somewhat thick thickness of about 30 mm.

On the other hand, a mask corresponding to the print contents should be used, and the used mask is stored until it is used again later. Therefore, the printing company stores a large number of masks.

However, as described above, since the frame of the mask is made to have a relatively large thickness and the volume of the mask is large, a considerably large space is required for storing the mask.
