Abstract
Official abstract text for this publication.
Provided is an air-permeable sheet (3) to be used in a state of being interposed between a suction stage (1) and an air-impermeable substrate (4) when printing is performed by a sheet-fed method on the surface of the substrate (4) fixed by suction to the suction stage (1), the air-permeable sheet capable of printing a desired printing pattern on the surface of the substrate with high accuracy. The air-permeable sheet (3) includes a non-woven fabric layer (3b) and a support layer (3a) constituted by a woven fabric or knitted fabric.
First claim
Opening claim text (preview).
The invention claimed is: 1. An air-permeable sheet to be used in a state of being interposed between a flat suction stage and an air-impermeable substrate when printing is performed on the surface of the air-impermeable substrate fixed by suction onto the suction stage, the air-permeable sheet comprising: a non-woven fabric layer being in contact with the air-impermeable substrate; and a support layer being in contact with the suction stage and formed from a woven fabric or knitted fabric. 2. The air-permeable sheet according to claim 1 , wherein the support layer has an opening of 70 to 400 mesh. 3. The air-permeable sheet according to claim 1 , wherein the non-woven fabric layer being in contact with the air-impermeable substrate is mainly formed from constituent fibers having a fiber diameter of 10.5 μm or less. 4. The air-permeable sheet according to claim 2 , wherein the non-woven fabric layer being in contact with the air-impermeable substrate is mainly formed from constituent fibers having a fiber diameter of 10.5 μm or less. 5. The air-permeable sheet according to claim 3 , wherein the non-woven fabric layer comprises conductive fibers or a surfactant. 6. The air-permeable sheet according to claim 4 , wherein the non-woven fabric layer comprises conductive fibers or a surfactant.
