ない。しかし当然のことながら、このような製版
工程は複雑であり、手間のかかるものであつた。 In general, lithographic offset printing is often used as a printing method. However, when there is only a small amount of printed area, for example when printing a store name on a calendar print, separate letterpress printing is often used. This is because, according to lithographic offset printing, the entire plate of a standard size must be used even for a small printing area, which increases the cost of plate materials. Additionally, letterpress printing is mainly used for printing small quantities. In this type of letterpress printing, the printing surface is often solid, including the printing of letters and symbols, so if you want to print halftone letters, etc., it is necessary to use a halftone screen etc. in the plate-making process. Halftone dots must be formed on the printing plate. However, as a matter of course, such a plate-making process is complicated and time-consuming.
本発明者らは以上のような現状に鑑み、種々研
究考察した結果、本発明を完成するに至つたもの

ることを特徴とする印刷方法である。 In view of the above-mentioned current situation, the present inventors have completed various studies and considerations, and as a result, have completed the present invention. That is, the present invention is a printing method characterized in that ink is applied to a plate on which halftone dots are formed, the ink is transferred to a letterpress plate provided on another plate holder, and the printing material is printed from the letterpress plate. It's a method.
以下、図面に基づいて本発明を更に詳しく説明
する。 Hereinafter, the present invention will be explained in more detail based on the drawings.
第１図は本発明の一実施例を示すものである。

種類の網点形成のされた版２を用意しておいて、
用途に応じて適宜交換するのが好ましい。 FIG. 1 shows an embodiment of the present invention.
A plate 2 on which halftone dots are formed is mounted around a plate cylinder 1, and ink is applied to the surface of the plate 2 by an ink application roller. The plate 2 has halftone dots with an appropriate halftone density, and may be a planographic plate, a letterpress plate, or a gravure plate. The part where the halftone dots are formed does not necessarily have to be only the part in contact with the relief plate 4;
It may be formed on almost the entire surface of the area. Further, the halftone dots may be formed at a constant density over the entire surface, or may form gradations. Prepare plates 2 with several types of halftone dot formation, such as those with different densities and those with gradations,
It is preferable to replace it as appropriate depending on the use.
凸版４は版保持体３上に設けられている。版保

ある。前記網点を形成した版２より凸版４にイン
キを転移すると、凸版４の版面には網点状にイン
キが着肉される。 The relief plate 4 is provided on the plate holder 3. As the plate holder 3, a plate cylinder or a plate surface plate is used. When an offset rotary printing press is used, a blanket cylinder may be used as the plate holder 3. The letterpress 4 is used to express characters, symbols, etc., and has a smooth surface. When ink is transferred from the printing plate 2 on which the halftone dots are formed to the relief printing plate 4, the ink is deposited on the printing plate surface of the letterpress printing plate 4 in the form of halftone dots.
しかる後該凸版４と印刷用紙等の被印刷物５と

る。 Thereafter, the relief plate 4 and a printing material 5 such as printing paper are brought into pressure contact to perform printing. As a result, printing material 5
Characters, symbols, etc. formed from halftone dots are printed on.
以上述べたように、本発明によれば網点状の文

期待されるものである。 As described above, according to the present invention, it is possible to easily print halftone dot-like characters and the like. Furthermore, it is easy to appropriately select and convert the type of halftone dots. Furthermore, since a normal letterpress can be used, the manufacturing process is simple. Therefore, by applying the present invention, it is possible to easily print halftone dots on characters, symbols, etc., which were conventionally done by letterpress printing, and its use is expected.
