Description
【考案の詳細な説明】 本考案はスクリーン型枠の製造において使用するスクリ
ーン紗に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a screen gauze used in the manufacture of a screen formwork.
現在布帛への柄模様の印刷、フレクシブルな紙、フイル

ーン印刷等にはスクリーン印刷による手段が広く利用さ
れている。この印刷に使用するスクリーン型枠には、紗
と呼ばれる布目の小さな薄い織物が張られている。At present, a screen printing method is widely used for printing a pattern pattern on a cloth, printing on a flexible paper, a film and the like, and further for printing a circuit pattern on a substrate which is important as an electronic component. The screen formwork used for this printing is covered with a thin, thin cloth called a gauze.
従来、スクリーン紗の素材としては、絹、ポリアミド、

リーン紗にされている。Conventionally, the materials for screen gauze are silk, polyamide,
Various kinds of natural or artificial organic filament yarns such as polyester and metal filaments such as stainless steel have been developed. Generally, these filament yarns are used as multi- or mono-filament yarns, and are structurally made into a screen gauze as a plain weave design in which each warp yarn and weft yarn have a proper gap.
スクリーン紗は用いられる経糸と緯糸の太さとこれら糸
間の間隙巾によつてその幾何学的性能が決定される。こ
の間隙巾は開口巾と紗密度の双方を決定する。このスク

一般的である。実際の印捺の際にこの最小単位である一
ます中を印捺剤が通過して点状の印捺が起こり、従つ
て、この点状の印捺が線でつながればラインを形成し面
でつながれば場を形成する訳である。The geometric performance of the screen gauze is determined by the thickness of the warp and weft used and the gap width between these threads. This gap width determines both the opening width and the mesh density. When looking at the smallest unit of this screen gauze, it is common to design so that the squares of the same length in both the warp and weft directions are formed. In the actual printing, the printing material passes through the smallest unit, one piece, and dot printing occurs. Therefore, if these dot printing are connected by lines, a line is formed. If they are connected, a place is formed.
以上のようなスクリーンの設計と機構から用いられる経
糸及び緯糸の太さが重要因子であり、画像形成の面から
みると密度が高いことが好ましいことは既に知られてい
る。It has been already known that the thickness of the warp and the weft used from the above screen design and mechanism is an important factor, and it is preferable that the density is high from the viewpoint of image formation.
しかしながら、スクリーン紗を工業的にしかも高密度
化、高精度化を必要とする分野で使用する場合、他の種
々の要因を考慮する必要がある。However, when the screen gauze is industrially used in a field requiring high density and high accuracy, various other factors need to be considered.
例えばスクリーン紗を用いて実際に印捺操作を行う場
合、その印捺の機構上でスクリーン紗には物理的変形が
起こる。この変形が規則正しく限定された一定の範囲の
ものでなければ厳密に同一品質の印捺物を作ることは不
可能である。従来知られたスクリーン紗はいずれも不規
則な物理的変形が起こり易く、長時間安定して同一品質
の画像を与えることは困難であつた。For example, when the printing operation is actually performed using the screen gauze, the screen gauze physically deforms due to the mechanism of the printing. It is impossible to produce a printed material of the exact same quality unless this deformation is within a certain range that is regularly limited. All of the conventionally known screen gabs are prone to irregular physical deformation, and it is difficult to stably provide images of the same quality for a long time.
本考案の目的は従来知られたスクリーン紗の上記した如

量を最適ならしめると共に長時間安定して使用し得るス
クリーン紗を提供することにある。The purpose of the present invention is to eliminate the above-mentioned drawbacks of the conventionally known screen gauze, particularly to reduce the amount of the printing agent deposited, to optimize the printing amount, and to use a screen gauze that can be used stably for a long time. To provide.
