With several thin grid Printing Zones, the stainless steel mesh cloth middle longitude is mutually perpendicular to weft, and the thin grid Printing Zone is parallel with warp,
The ratio between spacing A and spacing B of adjacent two warp in corresponding region between adjacent two thin grid Printing Zone is integer, each thin grid print
Brush area is respectively positioned between adjacent two warp.
In said structure, since the stainless steel mesh cloth middle longitude is mutually perpendicular to weft, the thin grid Printing Zone with
Warp is parallel, then warp is controlled usual stainless steel mesh cloth by warping apparatus in the fabrication process, has in screen cloth higher straight
Dimension and relative-position error, thin grid Printing Zone is parallel with warp can be conducive to the appropriate position of its selection to ensure thin grid
The intertexture node of warp and weft is avoided in Printing Zone as far as possible, thereby may be ensured that printing quality, makes thin grid thinner.Again due to phase
The ratio between spacing A and spacing B of adjacent two warp in corresponding region between adjacent two thin grid Printing Zones is integer, each thin grid printing
Area is respectively positioned between adjacent two warp, then corresponds to there are a certain number of warps and can protect between adjacent two thin grid Printing Zones
The spacing B demonstrate,proved between the spacing A between each adjacent two thin grid Printing Zone and adjacent two warp keeps certain relation, so as to
To ensure that the thin grid printed have required position, adjacent two are respectively positioned on more important is each thin grid Printing Zone can be made
Between warp, there is no the intertexture node for the warp and weft for influencing printing quality so between two warps, so that carefully
Grid width can be very thin, and printing quality can be guaranteed.
A kind of preferred embodiment of the utility model, the width C of the thin grid Printing Zone are less than between adjacent two warp
Away from B.Using the embodiment, thin grid Printing Zone can be made further to avoid the node that interweaves between stainless steel mesh cloth middle longitude and weft
Influence to printing quality.
Another preferred embodiment of the utility model, spacing A and corresponding area between each adjacent two thin grid Printing Zone
The ratio between domain middle longitude spacing B is definite value.Using the embodiment, the spacing A between each adjacent two thin grid Printing Zone is and warp
Spacing B keep identical multiple proportion, this can ensure to be printed thin when stainless steel mesh cloth middle longitude spacing B is very regular
Grid have equal spacing.
Another preferred embodiment of the utility model, spacing A and corresponding area between each adjacent two thin grid Printing Zone
The ratio between domain middle longitude spacing B includes definite value and adjusted value.Using the embodiment, it is ensured that between having a small number of adjacent warps
Spacing B and normal spacing the spacing A of each adjacent two thin grid Printing Zone is caused to remain to when being not completely equivalent there are certain deviation
Make thin grid Printing Zone between adjacent two warp by adjusting spacing A between corresponding adjacent two thin grid Printing Zone, from
And ensure that there is no the intertexture nodes of warp and weft in thin grid Printing Zone, it is ensured that printing quality.
The difference of the utility model further preferred embodiment, the definite value and adjusted value is ± 1.Using the embodiment party
Formula, it is ensured that the spacing A between each adjacent two thin grid printed is of substantially equal, and the difference of its spacing does not exceed stainless (steel) wire
Spacing B in cloth between adjacent two warp will not cause the influence to appearance and photovoltaic cell generating efficiency.
