Description

[Detailed Description of the Invention] The present invention relates to a stencil set in which a set of stencil tools for easily making a stencil from a stencil printing original plate by hand is housed in one container.

Traditionally, the methods for making stencils include writing on mimeograph paper coated with wax on washi paper with an iron pen or ballpoint pen, and then mechanically removing the wax and perforating it, or applying a solvent to dissolve and remove the wax. There is a way to drill holes. With the former, it is difficult to produce lines that are thicker than the thickness of the tip of a pen on the mimeograph paper, and it is not possible to perforate beautiful cursive writing like that of a calligraphy brush or cursive writing that has a large area, and the resolution is also poor. Ta. In the latter case, the dissolution rate of the wax was slow, so applying the solvent at normal writing speeds resulted in areas that could not be completely perforated, and the solvent used for perforation was also hazardous, which caused problems in handling.

The present invention uses a specific stencil printing plate and a specific plate-making liquid to hand-write desired patterns such as thin or thick line characters and patterns with a writing instrument without any problems in handling, and with good resolution. It is possible to make a stencil by punching holes. That is, the present invention combines a printing plate with a stencil printing original plate formed with a water-insoluble polymer film having tertiary amino groups on a porous support, and a writing instrument containing a plate-making liquid consisting of a water-soluble acid solution into one. It is characterized by being stored in a container. To make a stencil from a stencil printing original plate, a pattern is drawn on the stencil printing original plate with a writing instrument, the polymer film is treated with an acid solution of a stencil printing liquid, and the treated area is removed with water or a water-soluble liquid to form a stencil. do. Using this stencil, it is possible to easily obtain clear printed matter with a stencil printer by replenishing the stencil with stencil printing ink.

Even if either the plate to which the stencil printing original plate of this invention is attached or the writing instrument with built-in plate-making liquid are missing,
Or, even if one of them has different specifications, it is not possible to obtain a stencil that is easy to handle and has good resolution.

Embodiments of the invention are explained in the drawings.

A printing plate 1 and a writing instrument 2 are housed in a container 3 as a set. The printing plate 1 and writing instrument 2 may be stored in a bag (not shown).

As shown in Figure 2, the printing plate 1 has a third layer on a porous support.
A stencil printing original plate 4 on which a water-insoluble polymer film having a grade amino group has been formed is fixed to the lower surface of a frame 6 having a window 5 so as to cover the window 5, and is made of plastic such as PVC having a size that covers the window 5. One end of a transparent sheet 7 is fixed to the upper surface of the frame 6. One or more plates 1 may be stored in the container 3.

Cuts printed with patterns such as letters and patterns may be stored in the container 3.

The writing instrument 2 contains a plate-making liquid made of a water-soluble acid solution, and is provided with a pen 8 made of felt or plastic. The writing instrument 2 may be provided with a pen ₈₁ for bold characters and a pen ₈₂ for fine characters as shown in FIG.

The stencil printing original plate uses polyester, polyether, polyamide, and tertiary aminoalkyl acrylate polymers having tertiary amino groups, and vinyl pyridine homopolymers and copolymers as polymers having tertiary amino groups. A film is formed on a porous support, and this is used as a stencil printing original plate. The amount of polymer deposited is preferably 5 to 20 g/m ² .

These polymers include many compounds, such as esters of diols and dicarboxylic acids containing tertiary amino groups, diol polycondensates containing tertiary amino groups, and diamines containing tertiary amino groups. Polycondensate of and dicarboxylic acid, 3rd
homopolymer of grade aminoalkyl acrylate,
Copolymers of tertiary aminoalkyl acrylates with monoethylenic monomers such as acrylic monomers and/or styrene monomers, homopolymers of 2-vinylpyridine or 4-vinylpyridine, copolymers of 4-vinylpyridine and/or 2-pyridine with monoethylenic monomers, There are copolymers. These polymers are water-insoluble and themselves stable.

As the porous support on which the polymer film is formed, Japanese paper, nylon cloth, Tetoron cloth, nonwoven fabric, and other porous materials can be used. Also,
The thickness of the support is preferably about 20-150μ, and the aperture ratio is preferably about 25-60%.

A water-soluble acid solution is used as the plate-making liquid built into the writing instrument. Examples of the solvent include water that dissolves acids, alcohol polyols, and polyol ethers, and each solvent may be used in combination.

The acid in the acid solution reacts with the polymer to form a water-soluble reaction product. The water-soluble acids used preferably have a dissociation constant of 1.0×10 ^-5 or higher, such as inorganic acids such as hydrochloric acid, sulfuric acid, phosphoric acid, formic acid, acetic acid,
Organic acids include propionic acid, chloric acid, dichloroacetic acid, trichloroacetic acid, glycolic acid, lactic acid, oxalic acid, malonic acid, succinic acid, fumaric acid, maleic acid, malic acid, tartaric acid, and citric acid.

When these water-soluble acid solutions are used for home use or for infants, from the viewpoint of handling, it is most preferable to use organic acids such as citric acid and tartaric acid.

When applying the plate-making liquid to the stencil printing original plate, it is preferable to add a surfactant to the plate-making liquid in order to uniformly apply the plate-making liquid to the surface of the polymer. Further, in order to make the traces of the plate-making liquid placed on the stencil printing original plate clearly visible, it is preferable to dissolve a certain amount of dye. It is preferable to add a wetting agent such as a glycol in order to ensure that the plate-making liquid sufficiently wets the pen or impregnated body of the writing instrument, and further to prevent drying after filling. A method for quickly and easily producing a stencil with desired characters, patterns, etc. with good resolution using a combination of the above-described stencil printing original plate of the present invention and a plate-making liquid will be specifically described below. .

When a plate-making liquid is applied to the polymer adhered to the stencil printing original plate, the polymer and the acid in the plate-making liquid rapidly react only in the attached portions, producing a reaction product that is soluble in water or a water-soluble liquid. Therefore, when a stencil printing liquid is directly transferred onto a stencil printing original plate with a writing instrument, only the area of the stencil printing original plate to which the stencil printing liquid has adhered quickly becomes soluble in water or a water-soluble liquid. Next, the stencil printing original plate is made soluble in water or a water-soluble liquid by a water treatment such as immersing the stencil printing original plate in water for a few seconds or rubbing it lightly with a water-soaked sponge or absorbent cotton. After dissolving only the area in water and perforating it, it is dried to obtain a desired stencil with good resolution. Similar results can be obtained by treating with a mixture of water and polyols instead of water treatment. If you copy the plate-making liquid with a pen with a thin tip, you will get perforations with thin lines, and if you copy with a brush-like pen, you will get perforations that feel like a brush. Perforations can be obtained with good resolution.

By applying stencil printing ink to the perforated stencil as described above, attaching it to a stencil printer, bringing the stencil into contact with the printing paper, and pressing the stencil printing ink, a print corresponding to the color of the stencil printing ink can be obtained, and the color can be changed. By changing the color, you can print in the desired color.

In addition, if printing is performed by directly replenishing the stencil printing ink without treating the stencil printing original plate with the plate-making liquid attached to it with water or a mixture of water and polyols, water or water-soluble liquid Only the areas that are soluble in the printing ink are swollen and dissolved by the moisture or polyol in the printing ink, and are immediately transferred and perforated onto the substrate together with the stencil printing ink, so that printed matter can be obtained at the same time as the stencil is produced. . This method not only eliminates the step of water treatment, etc., but also eliminates the need for a drying step after water treatment, etc., making plate making extremely simple.

Furthermore, since the plate-making liquid is a solution containing water, this water can also be used to remove the treated polymer.

Next, an example of manufacturing a set according to the present invention will be described.

Production Example 1 A copolymer of dimethyl ethyl methacrylate and methyl methacrylate was applied to a 300-mesh Tetron screen and dried to obtain a stencil printing original plate, and a transparent sheet was attached to a frame to prepare a printing plate. 7.5 parts of citric acid, 0.04 parts of blue dye, 0.05 parts of Emulgen 810 (surfactant manufactured by Kao Atlas Co., Ltd.)
1 part was dissolved in 10 parts of water to obtain a plate-making liquid, which was incorporated into a felt-tip pen. Characters were written on the stencil printing original plate using this felt pen, and the stencil printing original plate was lightly rubbed with a sponge soaked in water to obtain a stencil plate in which the areas to which the printing liquid had adhered were completely perforated.

Production example 2 Polydiethylaminoethyl methacrylate 15
A 270 mesh nylon screen was immersed in a 270% methyl ethyl ketone solution, taken out and dried to obtain a stencil printing original plate, and this and a transparent PVC sheet were attached to a frame to form a printing plate. A plate-making solution was prepared by dissolving 3 parts of maleic acid and 0.02 parts of blue dye in 10 parts of ethylene glycol, and this was incorporated into a felt-tip pen. Place the cut under the stencil printing original plate, copy the pattern of the cut through the stencil printing original plate with a felt-tip pen, copy the cut pattern, rinse it with water, completely perforate the areas where the plate-making liquid has adhered, and dry the stencil printing original plate. A stencil version was obtained that fully reproduced the original shape.

When the stencil printing ink was applied to each part of the characters and figures of the stencil plates obtained in Production Example 1 and Production Example 2, and the plates were attached to a stencil printer and printed, it was found that the letters and figures were printed exactly as shown. Many beautiful prints with good image quality were obtained.

The present invention includes a plate with a specific stencil printing original plate attached to it, which is necessary for stencil printing, and a writing instrument containing a specific plate-making liquid for forming a pattern on the stencil printing original plate, so that the desired pattern can be created. Even young children can easily and safely make stencils with
