DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in more detail with reference to specific embodiments of the present invention shown in the drawings.

FIG. 1 is a schematic view showing the steps of the relief printing method of the present invention. First, as shown in FIG. 1A, a sandpaper 2 placed on a flat surface of a hard base material 1 is prepared, and a sheet material 3 plastically deformed by an external force is provided on one surface. An aluminum plate 32 having a thickness of 0.05 mm on which a latex layer 31 is formed is prepared, and an iron brush 4 is prepared as a means for pressing a part of the aluminum plate. These elements may be supplied in advance as a kit product for producing letterpress. FIG.
, The uneven surface 21 of the sandpaper 2 constitutes a crushable surface.

When a relief plate is formed, as shown in FIG. 1B, the latex layer 31 of the aluminum plate 32 is opposed to the uneven surface 21 of the sandpaper 2, and the aluminum plate 32 is After superimposing on 21, desired characters or illustrations are drawn while pressing the outer surface of the aluminum plate 32 with the iron brush 4 in the direction of the sandpaper 2. Then, the pressing force of the iron brush 4 causes the aluminum plate 3
2 protrudes downward together with the latex layer 31 to the substrate 1. At this time, the uneven surface 21 of the sandpaper 2 below the iron brush 4 is crushed while the other portions remain mounted on the uneven surface 21, so that the aluminum plate 32 follows the trajectory of the iron brush 4. A relief plate having the projection 33 is formed. Thereafter, when the sheet material 3 is peeled off from the uneven surface 21, FIG.
The letterpress composed of the sheet material 3 as shown in FIG.

As shown in FIG. 2, the sandpaper 2 used in FIG. 1 can be replaced with an elastic sheet 20 made of rubber, urethane, or the like. In this case, the same procedure is used as in FIG. It is clear that the letterpress can be formed. It is difficult to reuse the crushable uneven surface made of sandpaper or the like, but this elastic sheet 20 is advantageous in that it can be reused because it has a shape restoring property even when pressed. Also, the aluminum plate 32 and the sandpaper 2 or the elastic sheet 20 shown in FIGS. 1 and 2 may be provided as a unit which is previously releasably bonded via a latex layer 31. Further, the unit may be one in which the base material 1 is previously bonded to the sandpaper 2 or the elastic sheet 20.

As shown in FIG. 3, when a stamp is prepared using the letterpress obtained in FIG.
The stamp can be made by filling the concave portion 34 on the side of the aluminum plate 31 corresponding to the above with the adhesive 5 and bonding it to the grip 6. At this time, the convex portion 33 of the relief plate
Since the latex layer 31 is roughened by the uneven surface 21 of the sandpaper 2, the ink retaining property is enhanced and functions as an ink retaining layer.

In FIG. 1, the latex layer 31 can be replaced with a water-repellent layer. In this case, the convex portion 33 of the relief plate created according to the procedure of FIG.
While the surface is roughened by the uneven surface 21, the portion other than the convex portion 33 is water-repellent, so that the ink is selectively retained by the convex portion 33. Versions can be created.

On the other hand, as shown in FIG. 4A, the surface of the relief printing plate 3 obtained in FIG.
A curable fluid material 7 such as a molten rubber is poured into the fluid material 7.
After curing, as shown in FIG. 4 (b), if the cured body 7 'and the relief plate 3 are separated, a stamp made of the cured body 7' can be formed. At this time, in order to facilitate separation of the cured body 7 ′ and the relief 3, a release agent 35 may be applied to the surface of the relief 3 opposite to the convex portion 33.

FIGS. 5 and 6 show another embodiment of the relief printing method according to the present invention, in which the same sheet material 3 as described above is stamped by a print head 8 of a wire dot printer to obtain a relief printing plate. Is shown. As is well known, the print head 8 of the wire dot printer includes a large number of slidable pins 82 arranged in a dot matrix according to a pin guide 81, as shown in FIG. Each pin 82
Is provided with a driving means including a solenoid coil 83 and a magnet 84, and is independently slid by the driving means. All pins 82 are housed in a housing 85 together with their driving means. The housing 85 has an insertion hole 86 on the outer surface, and is slidably supported by inserting a slide bar (not shown) fixed to the printer main body through the insertion hole 86 in parallel with the platen roller 89. . The housing 85
Is connected to a drive belt 88 attached to the printer main body via a belt fixing base 87 provided on the outer surface, and is slid along a slide bar by driving of the drive belt 88.

Therefore, the wire dot printer of FIG. 5 slides each of the pins 82 while controlling the movement of the drive belt 88 and the platen roller 89 based on the image information read in advance by an image scanner or the like and converted into an electric signal. By doing so, an image corresponding to the image information can be reproduced as an aggregate of dots.

Thus, in order to create a letterpress, FIG.
As shown in FIG. 3, a relief printing sheet 3 in which an aluminum plate 32 is laminated on an elastic sheet 20 via a latex layer 31.
And prepare a wire dot printer. These may be provided as kit products. Thus, the relief printing sheet 3 is set on the wire dot printer, and the aluminum plate 32
By stamping the portion facing the platen roller 89 with the pin 82, the dot-shaped convex portion 33 is formed on the aluminum plate 32 to obtain a relief plate.

Incidentally, instead of the wire dot printer,
It is clear that a letterpress can be formed by embossing the same letterpress forming sheet 3 using a typewriter. It is obvious that a plastic sheet or the like can be used instead of the aluminum plate 32.

[0025]

According to the present invention, a sheet material that is plastically deformed by an external force is superimposed on a crushable or elastic surface, so that not only a handwriting operation with an iron brush or the like but also a stamping means such as a wire dot printer can be performed. It is possible to easily form a relief plate. This relief printing plate can be used as it is to form a stamp, or a rubber stamp or the like can be created using the back surface of the relief printing plate as a female mold.
