Abstract

The utility model provides a no net knot half tone, including gauze and the organic rete of setting on the gauze, a plurality of openings have been seted up on the organic rete, the gauze include many warps and with many wefts that many warps interweave each other, each opening is parallel with weft, and each the opening is located between two adjacent wefts. The utility model discloses a no net knot half tone is compared and is on a parallel with the half tone of warp in traditional opening, and the new method is directly done up, adopts the opening parallel with the weft, has avoided traditional plate-making in-process to remove warp in order to avoid the net knot, has improved the life of half tone.

Description

Screen printing plate without net knots

Technical Field

The utility model relates to a screen printing technical field especially relates to a no net knot half tone.

Background

In the existing plate making process of the screen printing plate without the net knots, when weaving the gauze, the warps are arranged at first, the wefts are woven in a subsequent inserting mode by using the shuttle, after the gauze is woven and formed, a corresponding film is required to be arranged on the gauze, the film is used for shielding a coating formed by the photosensitive resist, so that part of the photosensitive resist in the coating is shielded by thin grid lines on the film, in the subsequent exposure and development process, the photosensitive resist corresponding to the thin grid lines cannot be exposed under a light source when the screen printing plate is dried, and the final printing screen printing plate can be formed after washing. And when laminating the film, make thin grid line on the film parallel with warp as far as possible, however, because the interval between adjacent warp has already been fixed at the initial of knitmesh, follow-up unable adjustment, because thin grid line need be according to customer's demand and design alone in the film, inevitably, will have some thin grid line to be close to the warp or with warp coincidence, the screen version of so forming is close to the warp or is easy to appear the uneven problem of thickness or broken string with the silver line that the opening part of warp coincidence formed when printing the silver line. In order to solve the problems, the warps on the gauze and overlapped with or close to the thin grid lines need to be cut off and then drawn out, so that the service life of the screen printing plate is shortened.

SUMMERY OF THE UTILITY MODEL

The utility model provides a can simplify screen printing plate-making process, the high no net knot half tone of life of silk screen printing plate.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a no net knot half tone, includes the gauze and sets up the organic rete on the gauze, a plurality of openings have been seted up on the organic rete, the gauze include many warp and with many wefts that many warps interweave each other, each opening is parallel with weft, and each the opening is located between two adjacent wefts.

Further, the distance between the wefts is adjusted according to the position requirement of the opening on the screen without net knots when the gauze is woven.

Further, the distance between two adjacent weft threads positioned on both sides of any one opening is larger than the distance between two adjacent weft threads not provided with the opening.

Further, the distance between two adjacent weft threads provided with the openings is 100-200mm, and the distance between two adjacent weft threads not provided with the openings is 40-60 mm.

Furthermore, the gauze is made of metals or alloys such as stainless steel, tungsten steel, titanium, aluminum, copper, nickel and the like.

Further, the organic film layer is made of at least one of PET, PE, PI, PVC, PP, PTFE, PMMA and PS.

Further, the organic film layer is made of a photosensitive material.

The utility model discloses a gauze of half tone include many warp and with many warps are many weft that interweave each other, and the opening on the organic rete is parallel with weft, and each the opening is located between two adjacent weft, so when the establishment gauze, can adjust the interval between the weft in a flexible way to improve plate-making efficiency, and promote the life of half tone.

Drawings

The present invention will be further explained with reference to the drawings and examples.

Fig. 1 is a top view of a non-mesh halftone of the present invention;

fig. 2 is a schematic cross-sectional view of a screen of the non-knotted screen of the present invention;

in the figure: warp-101, weft-102, organic film-103 and gauze-104.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention. On the contrary, the embodiments of the invention include all changes, modifications and equivalents coming within the spirit and terms of the claims appended hereto.

Referring to fig. 1 and 2, a non-mesh screen printing plate includes a mesh 104 and an organic film 103 disposed on the mesh 104, the organic film 103 has a plurality of openings (not shown), the mesh 104 includes a plurality of warp threads 101 and a plurality of weft threads 102 interwoven with the warp threads 101, each opening is parallel to a weft thread 102, and each opening is located between two adjacent weft threads 102.

The pitch between the weft threads 102 of the screen cloth 104 can be adjusted according to the pitch of the openings on different screens when weaving the screen cloth 104.

In the present embodiment, the distance between two adjacent weft yarns positioned on both sides of any one opening is larger than the distance between two adjacent weft yarns not provided with the opening. Specifically, the distance between two adjacent weft threads provided with the openings is 100-200mm, and the distance between two adjacent weft threads not provided with the openings is 40-60 mm.

The gauze 104 is made of metal or alloy such as stainless steel, tungsten steel, titanium, aluminum, copper, nickel, etc., and the warp 101 and the weft 102 may be made of different materials or the same material.

The organic film layer 103 may be made of a cured polymer material such as PET (polyethylene terephthalate), PE (polyethylene), PI (polyimide), PVC (polyvinyl chloride), PP (polypropylene), PTFE (polytetrafluoroethylene), PMMA (polymethyl methacrylate), PS (polystyrene), or the like. When the organic film layer 103 is made of a high molecular material, an opening may be formed at a specific position on the organic film layer 103 by laser etching to form a print pattern.

The organic film layer 103 may also be made of a photosensitive material, photosensitive glue is coated on the gauze 104 in a coating manner, a film is arranged on the photosensitive glue layer, then the film is selectively cured under the irradiation of UV light, and a printed pattern can be formed on the organic film layer 103 after washing.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
