Applying a photosensitive emulsion layer (12) on the yarn thickness 2d, and then printing an ink on the insulating substrate; in the current more refined circuit, the unevenness of the surface of the ink printed by the structure is obvious, the film thickness is low, and the uniformity is poor.

In addition, the existing weaving mode of the plain weave screen printing plate can not bear scrapers and can cause the shape deformation of the plain weave screen printing plate due to larger pressure generated by the material characteristics of the plain weave screen printing plate; affecting the use.

However, the screen frame made of the wood material has poor solvent resistance and water resistance, is easy to deform after being soaked in water, can influence the printing precision, and is rarely adopted at present. The aluminum screen frame has the characteristics of convenience in operation, high strength, strong solvent resistance and water resistance, attractiveness, convenience in operation and the like, but is easy to deform under the tension of a metal net for a long time, the stability of screen printing ink is reduced, and metal foreign matters are easy to cause.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, embodiments accompanying the present invention are described in detail below with reference to the accompanying drawings.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be implemented in other ways different from the specific details set forth herein, and one skilled in the art may similarly generalize the present invention without departing from the spirit of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.

Furthermore, the references herein to "one embodiment" or "an embodiment" refer to a particular feature, structure, or characteristic that may be included in at least one implementation of the invention. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments.

Referring to fig. 2 and 3, in order to provide a first embodiment of the present invention, there is provided an ink-printed 3D screen printing plate,

the 3D screen printing plate 10 is a net-shaped structure formed by metal wires 11 which are arranged in a crossed mode according to warps and wefts, wherein the warp direction metal wires 11 are located on the same horizontal plane, and the weft direction metal wires 11 penetrate through the warp direction metal wires 11 for weaving;

and a screen frame 20 for fixing the edge portion of the 3D screen 10 so as to determine the planar shape of the 3D screen 10.

Specifically, the 3D screen 10 is different from the plain-weave screen in that the 3D screen 10 has a unique weave structure in which the weft direction wires 11 are only cross-woven and the thickness D2 is about 3 times the wire diameter of the wires 11, i.e., 3D. Therefore, the printing film thickness which is about 1.5 times of the thickness of the plain weave screen printing plate can be formed, and the leveling property and the uniformity of the film thickness after printing are obviously improved; the metal wires 11 in the warp direction are positioned on the same horizontal plane to form a horizontal reference plane, so that the deformation prevention capability is better.

The mesh structure is coated with a layer of emulsion 12 that can be patterned.

Specifically, the emulsion layer 12 is made of a photosensitive material commonly used in the art and is based on a process of printing ink on a circuit board for making a printed pattern, and completing the printing of the pattern, and belongs to the common knowledge in the art.

When the screen frame 20 is rectangular or square, the warp and weft rotate counterclockwise by 30-45 degrees simultaneously; more preferably, the warp and weft are simultaneously rotated counterclockwise by 30 °.

Specifically, the warps and the wefts rotate counterclockwise by a certain angle at the same time, so that the 3D screen printing plate 10 can bear larger pressure and is prevented from deforming; preferably 30 deg. to make the ink more uniform when printed.

The net frame 20 is a steel net frame.

Specifically, the steel mesh frame may be a mesh frame 20 made of stainless steel material, or other steel material with good strength and deformation resistance; thereby reducing the probability of metal foreign matters; the traditional plain weave screen printing plate can not bear the larger pressure generated by the scraper due to the material characteristic of the traditional plain weave screen printing plate, so that the shape of the woven gauze is deformed, and the 3D screen printing plate 10 can bear the larger pressure generated by the scraper due to the material characteristic of the traditional plain weave screen printing plate, so that the shape of the woven gauze is not deformed, and the uniformity of printing ink during printing is ensured.

It should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the scope of the claims of the present invention.
