Fig. 2 is the partial enlarged drawing of Fig. 1.
Detailed description of the invention
Technical scheme in this utility model embodiment will be clearly and completely described below, it is clear that described embodiment is only a part of embodiment of the present utility model rather than whole embodiments.Based on the embodiment in this utility model, all other embodiments that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Referring to Fig. 1 to Fig. 2, this utility model embodiment includes:
A kind of integrated without net knot composite halftone, including: fixed frame 1 and fixing silk screen 2, described fixing silk screen 2 is arranged on fixed frame 1, has been arranged concentrically printing screen 3 in described fixing silk screen 2, and described printing screen 3 is the integrated planar network structure of chemistry electroforming.The material of printing screen 3 can be according to different application characteristics when molding, and one or more mix to select copper, titanium, nickel, cobalt, tungsten, carbon, ferrum etc. respectively, to meet the tension of half tone, resistance to compression, the different requirements such as wear-resistant.
Described fixing silk screen 2 is polyester screen cloth, described printing screen 3 is densely covered with mesh, described mesh is hexagonal hole, square hole, one or more combinations in polygonal hole and circular port, particular design can be carried out according to original figure, described printing screen 3 first inputs computer the original figure needing printing before making, calculated by computer and need the pattern position of printing, generate reserved printing down to bit space 5, the mesh of bit space 5 is combined and comprises whole printed pattern by described reserved printing down, the most horizontal grid line lines, longitudinal figure frame, longitudinal anti-breaking grid line design and graphic chamfer, barrel hole size is 50-250um, it is preferably 100-200um.
During printing down film aligning in reserved printing down in bit space 5, through overexposure, development, form printing lines 4 so that printing lines 4 fall into the reserved printing interval without net knot.The non-printed areas mesh of described printing screen 3 is supporting and space 6, and the filling mesh openings of sizes of described supporting and space 6 is 20-150um, preferably 45-80um.After computer calculates and reserves printing contraposition space 5 and supporting and space 6 according to original print graphic hotsopt, electroforming generates integrated without net knot printing net.Owing to electroforming process technology is the most ripe, the most burdensome elaboration at this.
One or more chemical treatments such as silk screen surface can be roughened according to printing demand, polishes by described printing screen 3, melanism.Silk screen rough surface after roughened, can promote and the degree of being firmly combined with of photoresists, promotes the screen painting life-span；Silk screen smooth surface after polished, surface can be low, can promote the permeability of printing slurry, promotes printing performance；Silk screen surface after melanism is pitch-black, can reduce the irregular reference of ultraviolet when printing down, and the lines made are the most straight clearly.
It is coated with photoresists on described fixing silk screen 2 and printing screen 3, it is to avoid the seepage of ink during printing, promotes the quality of printing.Described fixing silk screen 2 includes the first silk screen and the second silk screen, and described first silk screen is compound to be arranged on the second silk screen.
It is respectively arranged with Printed Windows in the middle part of described first silk screen and the second silk screen; described printing screen 3 is arranged in Printed Windows; and the edge of printing screen 3 extends to the interlayer between the first silk screen and the second silk screen; it is provided with glue between described first silk screen and the second silk screen be connected and the edge of printing screen 3 is fixed, strengthens fixing silk screen 2 and the bonding strength of printing screen 3 and the fixing silk screen 2 protectiveness to printing screen 3 edge.
The first pattern, described fixed frame 1 includes ground floor framework and second layer framework, described ground floor framework is arranged on the top of second layer framework, the edge of described fixing silk screen 2 is arranged between ground floor framework and second layer framework, bolt is used to be fixedly connected between described ground floor framework and second layer framework, complex operation, but stationarity is good.
The second pattern, described fixed frame 1 is single layer structure.The edge of described fixing silk screen 2 uses glue to be connected with fixed frame 1, or, described fixed frame 1 is provided with and fixes the quick clip that silk screen 2 edge is connected, easy to operate, it is suitable for small-sized half tone and makes.
In sum, the one integrated nothing net knot composite halftone that this utility model is pointed out, without the staggered knot that reaches through parallel, each side is homogeneous plane, and stress is homogeneous, and figure stability is high, is conducive to quality and the fineness of lifting printing, and subject range is extensive.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical field, the most in like manner it is included in scope of patent protection of the present utility model.
