Description

Metal plain net half tone

Technical field

The present invention relates to a kind of printing screen plate, relate in particular to a kind of metal plain net half tone, the surfacing of metal plain net, the protruding anastomose of mesh grid as none does not have anastomose to move the problem of extending with grenadine yet, can promote precision, stability and the life-span of printing.

Background technology

General half tone is that the grenadine with thin,tough silk, nylon, Te Duolong, the formed square of steel wire opens on tetragonal screen frame, and its tensioning is fixed, coat on the grenadine with the macromolecular material emulsion, form the version film to block the mesh of strike through district external-open porose area through processing procedures such as exposure, developments again.As mentioned above, as the separating of figure, in order to forming print film, otherwise non-graph area is feeding zone every the surface, in order to the zone that will manifest by non-permeable material such as emulsion or macromolecular materials in grenadine surface portion zone.

Please refer to the drawing 1 and Fig. 2 take general combined type half tone as illustrative examples, mainly are to comprise a screen frame 10; One synthetic fibers grenadine 20 is bonded to this screen frame 10 around it, and has an opening 21 in the middle of this synthetic fibers grenadine 20; And a steel wire 30 is bonded to the opening 21 of aforementioned synthetic fibers grenadine 20.Wherein, steel wire 30 is that the yarn by a plurality of warp thread and weft yarn two directions descends weaving to form online, there is anastomose 31 on steel wire 30 surfaces and forms regular convex-concave surface, because grenadine itself has ductility, grenadine can prolong when printing scrapes, anastomose can move and mesh can be shifted, and therefore causes displacement and the deformation of printed pattern.

And, there is the anastomose 31 of projection on steel wire 30 surfaces, when printing rete (not shown) is the formed hatch frame thing that figure is arranged of emulsion, because emulsion is soft macromolecular material, the anastomose 31 that projection is arranged because of grenadine itself when squeegee pressure is larger can produce reticulate pattern or printed material is caused impression at the China ink layer that printed material prints.

And, stainless steel cloth 30 evenly coated by the use emulsion or synthetic fibers grenadine 20 is made required print film, because the retractility of grenadine is large, cause shedding deformation and displacement, emulsion also weares and teares easily or comes off, emulsion is coated stainless steel cloth or synthetic fibers on the net can be because the anastomose projection cause the print film out-of-flatness, causes Yin Mo to exosmose and prints and expand line or not straight.

Again, grenadine (synthetic fibers grenadine 20 or steel wire 30) is that warp thread and weft yarn are that up and down weaving forms, so therefore whole yarn is thick larger for the height of about two one threads of grenadine thickness.The thicker then strike through of grenadine more difficult and easy obstruction seal China ink or residual seal China ink cause Yin Mo to transfer to fully on the printed material, then can't print very hachure, for example the finger electrode of solar battery structure (finger); When printing very thin seal China ink, more because of the too high at present China ink of grenadine thickness amount, also can't reach the demand that the China ink layer is hanged down in printing, for example the bus electrode of solar battery structure (bus bar).

Summary of the invention

For solving the aforesaid drawbacks, the purpose of this invention is to provide a kind of metal plain net half tone, design by the metal plain net, improve the China ink layer that prints on mesh displacement, the printed material can produce reticulate pattern or to printed material cause impression, Yin Mo to exosmose and print expand line or not straight and be not easy to stop up the seal China ink or residual seal black, make the black demand of transferring to fully on the printed material of seal, also improve the not high problem of emulsion print film intensity.

In order to achieve the above object, metal plain net half tone of the present invention, it comprises: a screen frame, screen frame are the metal screen frame; Be bonded to this screen frame around the one synthetic fibers grenadine, this synthetic fibers grenadine be special how imperial screen cloth and stretchy nylon screen cloth one of them, and this synthetic fibers grenadine centre has an opening; Reach the opening that a metal plain net is arranged at this synthetic fibers grenadine, and this metal plain net have a plurality of mesh of evenly arranging.

Wherein, this metal plain net is that nickel, nickel alloy, stainless steel and other alloy are that material is made, and the mesh of this metal plain net is matrix to be arranged or the diamond array mode, and the mesh of this metal plain net is quadrangle, rhombus, circle or polygonized structure.

The invention has the advantages that, when the print film of opening figure is located on the metal plain net, because metal plain net surfacing, anastomose without projection, can reticulate pattern not arranged on the ink layer or cause printed material that impression is arranged because coining produces greatly when therefore printing, and the surfacing of metal plain net, can Yin Yinmo exosmose and cause expand line or the lines tangent line not straight; Because of the easy Sai Yinmo not of strike through, can also do the printing of Yin Mogao thickness demand; Again, the metal plain net can be very thin, can do thinner more accurate printing; And the metal plain net does not have, and grenadine extends, mesh distortion and anastomose move with problem, print rear size so figure can not be offset accurate, can promote the precision and stability of printing; The metal plain net is that metal material mass-energy improves anti-seal and anti-solvent, and then promotes the printing life-span.
