Screen plate and method for manufacturing same
To provide a screen plate that can allow printing accuracy to be improved. A screen plate comprising a plate frame and a screen gauze formed of warp and weft fibers each made of a synthetic fiber, wherein the screen gauze is stretched on the plate frame under application of a predetermined tensile force, and the thickness of the screen gauze stretched on the plate frame is 88% or less based on the thickness of the screen gauze under application of no tensile force.
1. A screen plate comprising
a plate frame, and
a screen gauze formed of warp and weft fibers woven in a predetermined weaving texture, wherein
the screen gauze is stretched on the plate frame under application of a predetermined tensile force,
the warp and the weft fibers are elongated by the predetermined tensile force applied to the screen gauze,
a thickness of the screen gauze stretched on the plate frame is reduced to 88% or less of a thickness of the screen gauze under application of no tensile force due to an elongation of the warp and the weft fibers,
a diameter of each of the warp and the weft fibers before weaving is 33 μm or less,
each of the warp and the weft fibers is made of a liquid crystal polymer, and
the predetermined tensile force is 21 N/cm to 36 N/cm.
2. The screen plate according to claim 1 , wherein the thickness of the screen gauze stretched on the plate frame is reduced to 70% or more of the thickness of the screen gauze under application of no tensile force.
3. The screen plate according to claim 1 , wherein the warp and weft fibers are monofilaments.
4. A method for manufacturing a screen plate, comprising
applying a predetermined tensile force to a screen gauze formed of warp and weft fibers woven in a predetermined weaving texture to elongate the warp and the weft fibers by the predetermined tensile force applied to the screen gauze and stretch the screen gauze on a plate frame, and
allowing a thickness of the screen gauze stretched on the plate frame to be reduced to 88% or less of a thickness of the screen gauze under application of no tensile force due to an elongation of the warp and the weft fibers, wherein
a diameter of each of the warp and the weft fibers before weaving is 33 μm or less,
each of the warp and the weft fibers is made of a liquid crystal polymer, and
the predetermined tensile force is 21 N/cm to 36 N/cm.
