【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、精細パターンを適正に印刷する印刷用板に

ようにしている。Conventionally, when a fine pattern is printed, offset printing is suitable. For example, a color filter used for a color liquid crystal display device is formed on a glass substrate by offset printing using R (red), G (green), and B (blue). Manufactured by printing ink. As shown in FIG. 4, a plate used for such offset printing includes a nickel plating layer 12 and a copper plating layer 13 (having a thickness of 6 to 10 mm) on a base layer 11 made of an iron plate as a material from the base layer side. 10μm)
The resist agent 15 is patterned on the copper plating layer 13 in a predetermined pattern (for example, a negative pattern of a plate surface and a negative pattern of an alignment mark) by using a plate 14 having a layer configuration provided with After the layer 13 is edged, the resist agent is removed to obtain a plate having a plate surface portion and an alignment mark portion, ie, an intaglio plate. Thereafter, a chrome plating layer is provided so as to cover the copper plating layer 13 so as to enhance the durability of the plate.

ニッケルメッキ層12はエッチング止めの働きを成すもの
で、このニッケルメッキ層12でエッチングを止め、版面

なるように設けられている。As shown in FIG. 4, the patterning of the resist agent 15 is performed by baking a predetermined pattern with a glass dry plate (master plate) 16 opposed to the plate 14. Then, etching is performed based on this pattern. The nickel plating layer 12 functions as an etching stopper. The nickel plating layer 12 stops the etching so that the plate surface portion and the alignment mark portion have the same depth.
しかしながら、上記版において、ガラス乾板の素材に
用いられている低膨張ガラスに対して膨張率が異なって
いる鉄板をベース層としていることから、上述の焼付を
経て得られた版面部とガラス乾板のパターンとに誤差が

必要とするカラーフィルタを、複数色のインキを印刷し
て得ようとする場合にあっては、前記の誤差によりパタ
ーンが規定ピッチからズレて不良を発生し易いという問
題があった。However, in the above plate, since the base layer is an iron plate having a different expansion coefficient from the low expansion glass used for the material of the glass dry plate, the plate surface portion obtained through the above-described baking and the glass dry plate are used. An error easily occurs with the pattern. In particular, as described above, when trying to obtain a color filter that requires a fine pitch pattern by printing a plurality of colors of ink, the pattern may deviate from a specified pitch due to the above-described error, and a defect may occur. There was a problem that it was easy.
そこで本発明は、マスター板のパターンに対して版面
部の誤差を小さくすることを課題とし、適正なピッチで
精細パターンをガラス基盤に印刷できるようにすること
を目的とする。Therefore, an object of the present invention is to reduce the error of the plate surface portion with respect to the pattern of the master plate, and an object of the present invention is to enable a fine pattern to be printed on a glass substrate at an appropriate pitch.
本発明は、上記した課題を考慮してなされたもので、
マスター板と同一素材の低膨張ガラスからなるベース層

とする印刷用版を提供して、上記課題を解消するもので
ある。The present invention has been made in view of the above problems,
The object of the present invention is to provide a printing plate characterized in that a plate surface portion is formed by a metal plating layer on the surface of a base layer made of low expansion glass of the same material as the master plate, and the above-mentioned problem is solved.
本発明においては、版のベース層がマスター板の素材
と同一であることから、焼付時にはマスター板と版とが
同じように膨張し、よって規定パターンに対する誤差が
きわめて小さい状態で版面部が形成されるようになる。In the present invention, since the base layer of the plate is the same as the material of the master plate, the master plate and the plate expand in the same manner during printing, so that the plate surface portion is formed in a state where the error with respect to the specified pattern is extremely small. Become so.
つぎに、本発明を第１図から第３図に示す実施例に基
づいて詳細に説明する。Next, the present invention will be described in detail based on the embodiment shown in FIGS.

めて小さいものとなっている。In the figure, reference numeral 1 denotes an intaglio offset printing plate, and a base layer 2 of the plate 1 is provided from low expansion glass which is the same material as the material of the master plate. On the surface of the base layer 2, a silver plating layer 3, a nickel plating layer 4, a copper plating layer 5
Is provided, and a chrome plating layer 6 is provided so as to cover the plate surface formed by a conventional method. With this configuration, the plate 1 expands in the same manner as the master plate at the time of printing, so that the error between the plate surface portion and the pattern of the master plate is extremely small.
