Abstract
The invention relates to a screen for silk-screen printing, which can cover all printable electronic products, in particular to a high-stability precision composite screen printing plate. The screen comprises an aluminum frame and screen cloth bridged on the aluminum frame, and is characterized by comprising a flat screen skip printing area located in the center of the screen cloth, and a non-graphic area on the outer edge of the flat screen skip printing area is bonded with the inner edge of the screen cloth; and the middle part of the flat screen skip printing area is an array regular polygon graphic area, and the width of the non-graphic area on the outer edge of the flat screen skip printing area is 20-30 mm. According to the high-stability precision composite screen, the problems that materials are wasted due to the fact that printing instability, the surface unevenness and proneness of print moire in a plate making process exist and a stainless steel wire mesh cannot be cut at a free angle in the prior art are solved; and more importantly, the line width and the opening of a flat screen skip printing layer can be designed according to the graphic minimum precision and the printing thickness, finally, the quality of a printing product is improved, the service life of a printing plate is prolonged, and the production cost is reduced.
Description
Technical field
The present invention relates to the half tone that a kind of serigraphy is used, cover all accurate composite halftones that can printed electronic product, particularly a kind of high stability.
Background technology
Development along with electronic product printing technology, industry to printing screen plate becoming more meticulous, the aspect such as printing resistance, resistance to dissolubility proposed higher specification requirement, the quality of printing screen plate is most important to the effect of final printing, affects to a great extent the yield rate of product.The screen printing plate that printing industry is used at present has polyester half tone, nylon half tone, stainless steel metal half tone and organic/several large classes such as metal composite half tone.Wherein, composite halftone has high resiliency, high-fineness, high stability and low elongation, is characterized in that printing precision is high, reproducible, the life-span is long.But also there are some defects: graticule node causes half tone surface irregularity; Graticule is compound to be easily distorted, and causes silk screen dislocation, affects printing precision; The defects such as the bad easy generation pattern edge sawtooth on line of photoresists bridge formation, broken string, moire; Longitude and latitude silk thread has strict directionality, and the inhomogeneous phenomenon of the compound easy generation tension force of stainless (steel) wire and polyester webs, affects printing precision and service life; According to paper size, making certain angle cuts and can bring waste of material problem.
Chinese patent CN 103192594 A disclose a kind of solar energy composite halftone, and this half tone is combined on metal plain net layer by the mode that applies or overlay by mask photopolymer layer, make two-layer composite web structure.Overcome the longitude and latitude node that in prior art, the wire netting of establishment type exists, effectively improved the surface smoothness of half tone.Yet the problem of itself and unresolved graticule directionality, cannot realize that free angle cuts and design live width and opening according to fineness and the thickness of printing.
The present invention proposes a kind of high stability and precision composite halftone, the problems such as the easy distortion dislocation of pair warp and weft line, the specific directionality of graticule require, tension force is inhomogeneous propose solution, printing precision and service life are improved greatly, realize free angle and cut, make good, the direction-free technical goal of figure bridge formation.Described high stability and precision composite halftone integrates the advantages such as the high-fineness, high stability, low elongation of high resiliency, high chemical resistance and the stainless (steel) wire of polyester webs, has the advantages that printing precision is high, reproducible, flatness is high, the life-span is long.With respect to above-mentioned solar energy half tone, its stability is higher, makes figure non-directional, builds bridge goodly can not produce moire, can set arbitrarily live width and opening according to the needs of figure, has solved the problem that conventional composite half tone manufacturing process exists.Along with the high development of electron trade, composite halftone was widely used in the industries such as FPC, semiconductor, liquid crystal display, backlight, solar energy, touch-screen in recent years, and market demand is very big.At present this invention verifies on actual production line, and result of use is good, and repeating print property is strong and pattern precision is high.
Summary of the invention
The object of the present invention is to provide a kind of accurate composite halftone of high stability, it can solve the problems such as surface irregularity, tension force inhomogeneities, the easy distortion of graticule of the current conventional composite halftone using, the bad and service life of building bridge be short.
For achieving the above object, technical scheme of the present invention is: a kind of accurate composite halftone of high stability, comprise aluminium frame and the screen cloth of building bridge on described aluminium frame, it is characterized in that: also comprise the plain net that the is positioned at described screen cloth center district of biting, described plain net bite the non-graph area of outward flange in district and the inward flange of screen cloth bonding; The described plain net district's mid portion of biting is the graph area that the regular polygon of array forms, and the bite non-graph area of the outward flange width in district of described plain net is 20 ~ 30mm.
In an embodiment of the present invention, described plain net is bitten and is divided into double-layer structure, and upper strata is stainless steel or the nickel alloy plain net layer of biting, and lower floor is photosensitive polymer barrier layer; Described photosensitive polymer barrier layer is evenly coated on stainless steel or the nickel alloy plain net layer bottom surface of biting.
In an embodiment of the present invention, the aluminum profile cross section of described aluminium frame is a kind of in the reinforced design of a day word, field word or X-shaped.
In an embodiment of the present invention, the outward flange of described screen cloth is fixed on described aluminium frame by the glue of high tensile force resistance.
In an embodiment of the present invention, the bite non-graph area of outward flange in district of described screen cloth and described plain net is carried out compoundly, and the method for utilizing cutter or heating forms the compound barrier of high-tension by exposing the plain net district of biting after peeling off in the middle of screen cloth.
In an embodiment of the present invention, described screen cloth is polyester webs or nylon wire screen cloth.
