【発明の詳細な説明】
（産業上の利用分野）
この発明は印刷特にオフセント印刷においてインキの滲
み、色すれかなく、高速印刷が可能で多色刷に最適な印
刷方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a printing method that is ideal for multi-color printing, in printing, particularly in offset printing, without ink bleeding or color fading, which enables high-speed printing.
（従来技術）
従来、印刷特にオフセット印刷においてはその印刷原理
からインキには酸化により固化する種類の遅乾性インキ
を使用し、１色を刷った後、数時間おいて２色目を刷り
重ねていた。又その際インキを版胴に巻付けられた版面
の非画線部には付着させず、画線部のみに付着させるた
め水を使用していた。(Prior art) Conventionally, in printing, especially offset printing, due to its printing principle, slow-drying ink that hardens through oxidation was used, and after printing one color, a second color was printed several hours later. . Also, in this case, water was used to make the ink adhere only to the printed areas, not to the non-printed areas of the printing plate wrapped around the printing cylinder.
（発明が解決しようとする問題点）
しかしながら上記の方法においてはインキの乾きが遅い
ため先の印刷工程を終った印刷物のインキが後からその
を上に植重ねられた印刷物の裏面にインキが付着しない
ように積重ね高さを制限したり、或は澱粉類の粉を印刷
された面に吹付ける等の必要があった。(Problem to be solved by the invention) However, in the above method, since the ink dries slowly, the ink of the printed matter that has finished the previous printing process sticks to the back side of the printed matter that is later stacked on top of it. It was necessary to limit the stacking height or to spray starch powder onto the printed surface.
又、印刷時の水により紙面が湿るため充分に乾燥させる
必要もあった。In addition, since the paper surface becomes wet due to water during printing, it is necessary to dry the paper thoroughly.
このため印刷物を積重ねるだめの場所が広く必要となり
、乾かすための時間を要し、又、粉を吹付けたものは次
の印刷工程でプランケットやゴム等が巻かれたプラン胴
に付着して色渡りを起し、印刷面を汚す等の不都合があ
った。For this reason, a large space is required for stacking the printed matter, and it takes time to dry it. Also, the powdered material may adhere to the plan cylinder wrapped with plunkets or rubber during the next printing process. This causes problems such as color migration and staining of the printed surface.
このような不都合の点は絵柄の少い色のインキより刷込
むようにすると成る程度回避することができるが、その
都度色別の絵柄の多少により刷り込みの工程を変更する
ことは印刷の都合上困難であり、特に多色機の場合は無
理である。These inconveniences can be avoided to some extent by printing with ink of a color with fewer patterns, but it is not convenient for printing to change the printing process depending on the number of patterns in each color each time. This is particularly difficult for multi-color machines.
又、水を使用するために、紙が伸びて２色目、３色目の
刷込みの位置ぎめが困難で色ずれを起す等の問題点もあ
った。In addition, since water is used, the paper stretches, making it difficult to position the second and third color imprints, resulting in color misalignment.
（問題点を解決するための手段）
この発明は上記したような不都合の点をなくし、高速印
刷が可能なようにした印刷方法であって、先の印刷装置
１より次の印刷装置２に到る間に印刷紙３面上に低粘性
であって速乾性の溶剤系透明樹脂液４を吹付けて、該透
明樹脂液４による薄い透明の皮膜５を形成するようにし
たものである。(Means for Solving the Problems) The present invention is a printing method that eliminates the above-mentioned inconveniences and enables high-speed printing. During this time, a low-viscosity, quick-drying solvent-based transparent resin liquid 4 is sprayed onto the surface of the printing paper 3 to form a thin transparent film 5 of the transparent resin liquid 4.
（作用）
先の印刷装置ｌの印刷を終った印刷物は未だインキの乾
かない、しかも水で湿った状態であるが透明樹脂液４を
吹付けられ、 ８Ｉ１．樹脂液４が速乾性の溶剤系であ
るので、直に透明の樹脂皮膜５を形成し、印刷紙３面上
を覆い、印刷された絵柄等のインキ７°上も覆われる。(Function) The printed matter that has been printed by the previous printing device 1 is sprayed with the transparent resin liquid 4 even though the ink has not yet dried and it is still wet with water. 8I1. Since the resin liquid 4 is a quick-drying solvent type, a transparent resin film 5 is directly formed and covers the surface of the printing paper 3, and also covers 7 degrees of ink such as a printed pattern.
又、印刷紙３は水によって湿っていても上面への皮膜５
の形成によって伸びることを抑止される。樹脂液４は速
乾性で更に低粘性の樹脂であるため、皮膜５は次工程に
達する迄に皮膜５となり、印刷時にもローラー等に付着
することがない。Moreover, even if the printing paper 3 is moistened with water, the film 5 on the upper surface remains.
elongation is inhibited by the formation of Since the resin liquid 4 is a quick-drying and low-viscosity resin, the film 5 becomes a film 5 by the time it reaches the next step, and does not adhere to rollers or the like during printing.
（実施例）
図面はこの発明の一実施例を示す印刷装置の構成の概略
を示すもので、１は先の印刷装置であって版胴１ａ、ブ
ラン胴１ｂ、圧胴１ｃよりなり、２は先の印刷装置ｌと
同様な構成の次の印刷装置である。(Embodiment) The drawing shows an outline of the configuration of a printing apparatus showing an embodiment of the present invention, in which 1 is the printing apparatus, which is composed of a plate cylinder 1a, a blank cylinder 1b, and an impression cylinder 1c; This is the next printing device with the same configuration as the previous printing device 1.
３は印刷紙であり、通常枚葉紙が用いられており、印刷

形成するようになっている。Reference numeral 3 denotes printing paper, which is usually a sheet of paper, and is printed by a printing device 1 and then sent to the next printing device 2. Reference numeral 6 denotes a nozzle installed immediately after the printing devices 1 and 2, which sprays a low-viscosity, quick-drying, solvent-based transparent resin liquid 4 onto the 3 sides of the printing paper sent out by the impression cylinder IC and the blank cylinder 1b. As a result, a transparent resin film 5 is formed on the printing surface.
６°は印刷装置２の直後に設けたノズルであり、更に次
の印刷に備えて設けられたものである。6° is a nozzle provided immediately after the printing device 2, and is provided in preparation for the next printing.
このようにして印刷されると、第２図のように先の印刷

°を形成して覆うものである。When printing is performed in this manner, a film 5 is formed by the transparent resin liquid 4 sprayed by the nozzle 6 over the entire surface of the printing paper 3 printed by the previous printing device 1, as shown in FIG. Since the top of the ink 7 is also covered, there will be no color transfer or bleeding when the next printing device 2 prints, and the ink 7° is printed on the surface of the film 5, and then the next nozzle 6' prints. Film 5 on top of film 5 and ink 7°
It forms and covers the °.

や滲みを起すことがない。(Effects) As described above, the printing method according to this invention sprays a low-viscosity, quick-drying, solvent-based transparent resin liquid onto the printed paper surface between the first printing device and the next printing device. By forming a thin transparent film with the transparent resin liquid, the thin transparent resin film is formed until it reaches the next printing device and covers the printing surface, so that the blank cylinder of the first printing device Ink will not stick to the surface and cause color transfer or bleeding.
２ 印刷時に使用する水により紙が伸びるのを防止する
ので１次の刷込み時の位置決めがしやすく色ずれを起さ
ず、又、先の紙と後の紙との伸びによるダブリがない。2. Water used during printing prevents the paper from stretching, so positioning during the first printing is easy and color shift does not occur, and there is no overlap due to stretching between the first and second sheets.

と同様に使用することができる。Therefore, in the case of color printing, a four-color machine is usually used;
Consists of indigo, sekihan, and color plates, and uses special colors.
In the case of color printing, printing is difficult because it must be set on a separate machine, but with this method, printing can be repeated without color shift due to positional misalignment, so there is no need for a black plate, and that amount is used for printing metal colors, special colors, It can be used as a plate for fluorescent ink, glazing, and matting, and there is no positional shift, and a 4-color machine can be used in the same way as a 5-color machine.
３ 薄い透明の樹脂皮膜であるため紙質に特に影響はな
く、皮膜への次の印刷のインク乗りが良好である。3. Since it is a thin transparent resin film, it does not particularly affect the paper quality, and the ink transfer to the film is good for the next printing.
４ 樹脂液が低粘性で速乾性であるため、乾燥時間が速
く、高速印刷が可能であり、又、従来の乾燥のだめのス
ペースが不要でＪ〕す、設備コストが低下する。4. Since the resin liquid has low viscosity and dries quickly, drying time is fast, high-speed printing is possible, and there is no need for the conventional drying tank space, reducing equipment costs.
５ 前記のように位置ずれなく刷重ねられるので多色機
に最適である。5. As mentioned above, it can be printed over and over again without positional deviation, making it ideal for multi-color machines.
