Description

Dual network version structure

This creation is about a screen structure, in particular, a dual-network screen structure formed by two layers of mesh.

Screen printing is an important tool for screen printing, and it can also be said to be an important basis for screen printing. The screen is mainly formed by Tedragon fiber, nylon fiber or metal mesh material, which is cross-woven in the warp and weft directions, and then fixed by a certain tension to be fixed on a frame. In addition to forming the pattern, the screen version also controls the amount of ink that is transmitted during screen printing; therefore, the screen has a very large influence on the precision of printing, the thickness of the ink, and the amount of ink permeation.

The printing principle of screen printing is to use the chemical reaction of the emulsion to the ultraviolet light and the holes formed by the warp and weft of the screen to perform photosensitive plate making, so that the non-printed portion is photohardened to block the mesh. The printed portion is dissolved and hollowed out when it is exposed to water because the emulsion does not react chemically. When screen printing is performed, the operator can apply pressure by the doctor blade to scrape the ink, so that the ink is printed on the printed matter through the hollow mesh to achieve the printing purpose.

In general, the thickness of the printed pattern depends on the thickness of the screen mesh and the emulsion layer. Therefore, when a thicker printed pattern is required, the current solution in the industry is nothing more than thickening the thickness of the mesh or emulsion layer. However, in order to form a thicker mesh, The wire diameter of the mesh material used is relatively thick, and the screen plate composed of the wire material having a relatively large wire diameter is likely to cause ink overflow during printing, and the printed pattern lines printed thereon may also be The disadvantage of being uneven and not sharp. In addition, if a thick emulsion layer is used, in addition to the difficulty in controlling the thickness of the emulsion layer, the overall structure of the screen may not be stabilized.

For the above reasons, the purpose of the present invention is to provide a dual-network screen structure that utilizes the structure of a two-layer net to thicken the thickness of the screen, thereby providing a thicker printed pattern.

Another object of the present invention is to provide a dual-network screen structure that utilizes a double-layered network structure to provide a thicker and structurally stable screen.

A further object of the present invention is to provide a dual-network screen structure which utilizes two different properties of the mesh layer to form a thicker screen, so that the screen can be smoothly attached to the printed matter.

To achieve the foregoing objective, the present invention provides a dual screen screen structure comprising a metal mesh fixed to a frame and covered by a cured layer having a plurality of pattern openings. The dual-network screen structure is characterized in that the metal mesh system is composed of a first metal mesh layer and a second metal mesh layer, and the first metal mesh layer is fixed on the second metal mesh layer. .

According to an embodiment of the present invention, the first metal mesh layer is interlaced by a plurality of first metal mesh wires, and the second metal mesh layer is interlaced by a plurality of second metal mesh wires, and the The plurality of first meshes formed by the first metal mesh lines are larger than the plurality of second meshes formed by the second metal mesh wires.

According to an embodiment of the present invention, the first metal mesh layer is interlaced by a plurality of first metal mesh wires, and the second metal mesh layer is a metal flat having a plurality of flat mesh holes. The network consists of.
