Abstract

PROBLEM TO BE SOLVED: To avoid plate clogging and upgrade print quality while ensuring the rapidity and simplicity of a rotary stencil printer by preparing a stencil printing plate cylinder to which a pair of stencil printing plate frames opposite to a heat-sensitive stencil printing plate are fixed in a freely attachable/detachable manner and mounting the stencil printing plate cylinder on the rotary stencil printer. SOLUTION: A stencil printing plate made up by a make-up device for a heat- sensitive stencil printing paper is fixed to a stencil printing plate frame to form a stencil printing plate cylinder 3. Further, the cylinder 3 is made to rotate, while an image receiving sheet 99 supplied from a sheet supply table 52 through a sheet guide plate 53 is brought into contact with the outside of the cylinder 3. At the same time, ink supplied into an ink fountain part 56 from an ink supply part 58 is squeezed out of the perforated part of the cylinder 3 by means of a squeegee or the like, while a press roller 55 is pressed to the outside of the cylinder 3. Then, the ink is transferred to the image receiving sheet 99 and thereby a printed matter is prepared. After that, the used cylinder 3 is stored in a printing plate depositing box 60 by means of a printing plate ejecting roller 59.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stencil printing method and apparatus.

[0002]

2. Description of the Related Art Rotary stencil printers are widely used because they can produce printed materials at a low cost and at a high speed by a simple operation like copying. However, in this rotary stencil printing machine, if the ink setting property (fixing property) is insufficient,
When the printed matter is overlaid, there is a problem that the back side of the printed matter is stained or the ink drops when the printed matter is rubbed.

Several proposals have been made to improve the shortage of the ink setting property. For example, Japanese Patent Application Laid-Open Nos. 1-318073 and 2-413
No. 76 and Japanese Unexamined Patent Application Publication No. 8-3501 disclose an ultraviolet curable ink which develops set properties by ultraviolet irradiation. However, these inks have a problem in that the use of a large amount of expensive ultraviolet curable resin, photopolymerization initiator, and sensitizer inevitably increases the cost of the ink. Also, JP-A-8-230306, JP-A-8-239613, JP-A-8-245915, and JP-A-9-99
622 and JP-A-9-295452 disclose a stencil printing ink and a stencil printing method that change from a solid to a liquid by heating. However, this ink and the stencil printing method have a problem in terms of environmental stability because the fluidity of the ink changes sensitively due to the difference in the outside air temperature.

[0004] As a method of giving ink set properties,
In screen printing and offset printing, naturally curable inks that cure over time by using a volatile solvent for volatilization or containing an oxidative polymerization component for crosslinking are generally used. These inks are available at low cost and have high environmental stability. However, when such a natural curable ink is used in a normal rotary stencil printing machine,
As a result of the volatile solvent being volatilized or the oxidative polymerization component being cured after being left on the machine for a long time, holes in the mesh body of the plate cylinder are clogged and printing cannot be performed again.

However, in the case of a general flat screen printing plate, clogging can be avoided by using a naturally curable ink by wiping the ink on the plate after printing or by replacing the whole plate. Based on the same idea,
Japanese Patent Laid-Open Nos. 0-180974 and 10-202821 disclose thermal gauze. In these methods, after printing, the used thermal gauze is discarded and replaced with a new thermal gauze. Ink can be used. However, since all of these methods use a flat plate, it is impossible to perform printing at a high speed like a rotary press, and it is not satisfactory.

Another method is disclosed in Japanese Patent Application Laid-Open No. 56-64897.
In Japanese Patent Laid-Open Publication No. H10-209, an exchangeable rotary screen printing plate is disclosed. High speed printing is possible because of the rotary type,
In this method, since a photolithographic plate is used, a series of complicated operations following the preparation of a lithographic film, coating of a photosensitive emulsion, exposure, and development using chemicals are inevitable, and workability is extremely poor. I'm not satisfied. This method also has a great disadvantage in that clogging can be avoided even when a naturally curable ink is used, but the advantage of a high-speed and simple rotary stencil printing method is eliminated.

[0007] Further, the image quality of any conventional rotary stencil printing machine is inferior to that of offset printing or the like. In particular, there is a lot of roughness from the highlight to the halftone. This is because offset printing has a mechanism for determining the thickness of the transferred ink by forming an ink thin film on the plate surface with a uniform thickness.

According to the method using a replaceable rotary screen printing plate described in the above-mentioned JP-A-56-64897, the ink can be packed in the holes of the plate and quantified by the thickness. An effect similar to that of offset printing can be obtained, and as a result, the thickness of the transferred ink can be made uniform and the roughness can be reduced. However, as described above, this method is extremely poor in workability, and in addition to erasing the advantages of the simple rotary stencil printing method, the light spreads due to the diffraction phenomenon when exposing the photosensitive emulsion, so that the resolution is increased. It is not possible to make a high-definition image because it can not be raised,
The disadvantage is that it can only be used for printing coarse images.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in more detail. 2. Description of the Related Art A plate cylinder of a conventional general rotary stencil printing machine includes a mesh body fixed so as not to be easily attached to and detached from a plate frame, and a plate wound from above. Normal,
In a rotary stencil printing machine, ink is left in a plate cylinder for several days from the end of printing to the next printing. If the ink hardens during this standing period and the holes in the plate cylinder are clogged, printing cannot be performed again. Therefore, in general, rotary printing stencil printing is limited to inks that do not easily harden over time. However, while using ink that does not cure over time, clogging does not occur, or the back side of the printed matter is stained when the printed matter is overlaid, or the ink falls off when the printed matter is rubbed, so-called A defect occurs due to insufficient ink setting.

When an ink containing an oxidative polymerization component such as a volatile solvent, a resin, or a drying oil is used in order to enhance the ink settability of the plate cylinder, the ink evaporates when the ink is left after printing. As a result, a part of the ink is cured by oxidative polymerization, resulting in clogging of the mesh body.

On the other hand, in the present invention, a stencil printing plate cylinder is constituted only by a stencil printing plate frame and a thermosensitive stencil printing plate easily detachable from the stencil printing plate frame. The above problem can be effectively solved by discarding the printing plate and replacing it with a new heat-sensitive stencil printing plate. According to the present invention, the heat-sensitive stencil printing plate can be easily replaced even if the ink is used for a long time after the use of the naturally curable ink, so that printing can be performed again without clogging. Therefore, it is possible to repeatedly obtain a printed material on which the ink is set.

Although clogging can be avoided by using a flat screen printing plate or a rotary screen plate, high speed printing or simple operation is sacrificed. In the present invention, preventing clogging,
High-speed printing and simple operation can be compatible.

In a conventional rotary stencil printing machine, a stencil printing plate is wound around the outside of a plate cylinder in which one or a plurality of mesh bodies are formed in a cylindrical shape, and a printing pressure is applied to a nip portion to discharge ink. However, where the ink runs out in the portion where the stencil printing plate and the mesh body overlap is unstable and not constant. Therefore, the amount of ink to be drawn is not constant depending on the location, and the thickness of the transferred ink is not constant for each perforation, so that the dot area varies and only a rough image can be obtained. there were. However, in the present invention, the peripheral surface of the plate cylinder is constituted only by the stencil printing plate, and the ink is transferred to the image receiving paper while removing excess ink on the back side of the stencil printing plate with a squeegee or roller inside the plate cylinder. For,
The thickness of the transferred ink is determined by the thickness of the stencil printing plate and can be constant. As a result, the size of each dot can be made uniform, and the roughness can be greatly reduced.

The stencil printing of the present invention is of a rotary type, so that high-speed printing is possible. In addition, since stencil printing can be performed in a dry manner by using a heating means such as a resistance heating element, it is significantly different from a conventional method using a screen stencil. Work can be simplified. Further, the stencil printing of the present invention can effectively solve the above-mentioned problems while satisfying the high-speed printing property and the simplicity of stencil making of a conventional rotary rotary stencil printing machine.

In the present invention, specific examples of means for detachably fixing the heat-sensitive stencil printing paper or the stencil printing plate to the stencil printing plate frame include holes provided in the heat-sensitive stencil printing paper.

The end of the heat-sensitive stencil printing plate or the stencil printing plate is fixed by a method such as providing an adhesive, an adhesive, or a concave portion and a convex portion and fitting them, or by heating and fusing to form a cylinder. However, other methods can be used as long as the ends can be smoothly joined.

From the viewpoint of mechanical strength, it is preferable to use gauze (screen mesh).

In order to provide a porous support on the thermoplastic film, when the support is formed of a porous resin film, the resin solution is applied and dried, and the adhesive is applied. When using other porous supports, a thermoplastic porous support may be used for heat-sealing and bonding, or an adhesive layer may be formed between the thermoplastic film and the porous support to bond. You may. The adhesive layer can be formed by applying an adhesive to a thermoplastic film, or by applying and spraying an adhesive on a porous support, or immersing the porous support in the adhesive. When an ink containing a large amount of an organic solvent is used, it is preferable that the adhesive contains a component that is cured by heat, ultraviolet rays, electron beams, X-rays, or the like, from the viewpoint of improving durability.

The heat-sensitive stencil printing paper that can be used in the present invention is usually made by a thermal head.
