Abstract

Many clear pictures can be reproduced easily at home. Ink is sprayed on a 2-dimensional coordinate point on the approximately flat surface of a porous body by an ink jetter. The ink is a light absorbing ink. A certain quantity of ink penetrates into small pores at a high speed. After the ink spray, flash light is applied to the ink adhering to the flat surface and the hole surfaces in the small pores. The ink absorbs the light and the parts of the porous body where the light is absorbed are locally melted and the small pores are filled. The regions where unfilled pores are distributed are coated with color paint with a brush, a marking pen, etc. A master printing plate produced like this can be used to transfer an image to transfer papers repeatedly until the ink in the small pores is completely consumed.

Stamp surface creation method and stamp surface creation device

The present invention relates to a stamp creation method and a stamp creation device. More specifically, the present invention relates to a method and an apparatus for easily creating a clear stamp with an arbitrary pattern at home or at a stationery store or a specialty photo shop. Background art

Engraving and replicating sculptures created arbitrarily is spreading worldwide as a hobby world. Not only hobbyists but also professional printmakers are required to quickly create prints that are duplicated and unique one by one.

Rubber stamps, for which it is easy to form an uneven image, are used to strongly press the stamp surface against transfer paper to reproduce a sharp image. Cannot be played. Also, when performing color transfer, it is necessary to create multiple identical rubber stamps, but it is difficult to create multiple identical rubber stamps. It is troublesome because it needs to be changed many times.

A new technology that can be easily reproduced many times by applying one ink from one plate has recently attracted attention. As the inventor's own prior art,

No. 6 1-5 6 0 7 0 is known. The stamp surface known in this publication is formed by engraving a concavo-convex image on a substrate made of a foamed elastomer. If an ink is applied to the protruding portion with a brush or a marking pen, the ink penetrates into the protruding portion of the continuous porous body and stores a certain amount of the ink. The same image can be reproduced several times. color Since the coating is performed artificially, colorization is easy. Such a stamp making method, which can create an interesting pattern by transferring the same pattern regularly or randomly on the same transfer paper, is popular among children. The surface of the porous body is overlapped with an existing film on which a popular character or the like is drawn, and the surface of the porous body is irradiated with flash light. There is also known a method in which a hole is crushed and ink is impregnated into an uncrushed hole. Such a method is known from Japanese Patent Application Laid-Open No. 7-285528. Such a porous body for forming a stamped surface is known from Japanese Patent Application Laid-Open No. H6-1555698, and it is known that a polyolefin-based foam is particularly suitable.

In such a method using a film, the flash light is strongly reflected irregularly at the edge of the image drawn on the film, and the light is repeatedly reflected between the front and back surfaces of the film. It is known that the image becomes blurred.

In order to eliminate such blurring, the following method can be proposed. When a heat-absorbing ink is applied to the surface of the porous body with a writing instrument such as a brush, and then the surface is irradiated with heat rays, the ink-coated part absorbs the heat rays and the heat ray-absorbing part dissolves, causing pores on the porous surface. Collapses or closes. According to this method, it was difficult to penetrate the ink into the fine pores, so that the distribution density of the heat absorbing medium was uneven, and it was confirmed that the blurredness of the reproduced image could not be eliminated. .

Stamp creation technology that can freely change the image, sharpen the reproduced image, facilitates colorization, promotes free drawing by each person, and enables continuous continuous reproduction with one color painting Has been requested.

Disclosure of the invention

ADVANTAGE OF THE INVENTION The stamp surface preparation method and its apparatus by this invention can close the hole of the substantially flat stamp surface of a porous body, or can crush the hole of the stamp surface. An infinite number of continuous fine pores are formed in the porous body. The myriad of holes running in a direction perpendicular to the plane surface are connected in the horizontal direction and distributed in a three-dimensional mesh.

On a planar surface of the porous body, if observed microscopically, for example with an electron microscope, some of the myriad of holes are open at the surface and others are closed at the surface without opening at the surface. However, when viewed macroscopically, i.e., at the level of resolution required for a painting to be viewed with the naked eye, it can be considered that the pores that open at the surface are continuously and uniformly distributed at a similar density on the surface. Can be.

Point, ellipsoidal, and columnar inks are sprayed onto the surface of the porous body. air Due to resistance and surface tension, the top of the dot-like, ellipsoidal, or cylindrical liquid ink mass is shaped like a teardrop while running at high speed through the air after being injected from the injection port. . The top of the ink mass flying at high speed in such a form collides with the capillary at the center point area of the small surface area of the porous body and infiltrates to the surface layer to a depth of several tens of microns. And cover the surface of the capillary. The continuous micropores form the first and second layers to form a gourd cell. Inks that are ejected and penetrate into capillaries around the center point area, that is, point-like areas containing such a collection of cells, have a shallower penetration into the cells as they move away from the center point. The ink intrusion area can be considered substantially as a point area. When the image is reproduced, the area around the central bright spot is slightly blurred if detected by a strict light meter, and the blur cannot be clearly recognized by the naked eye. However, it gives the viewer somehow the feeling of watermarking and blurring, and this feeling is rather desirable.

The most important advantage of such ink irradiation is that the ink of a fixed volume of liquid that collides at a high velocity must be applied in the longitudinal direction of the porous body before it spreads laterally, i.e., on the surface of the porous body. It does not penetrate vertically into the micropores and diffuse on the surface of the porous body. This non-diffusion makes the reproduced image clear. When light is directly applied to the porous body by passing light through the film with the image drawn on the front or back side by aligning the light with the surface of the porous body, the light is applied to the image and the front and back of the film. The sharpness of the reproduced image becomes extremely poor because of the reflection and diffusion of light.However, in the present invention, instead of direct irradiation of light, an ink having a high heat absorption property generates heat to indirectly dissolve the porous material. And the reproduced image is also sharpened at this point. When an image is formed on the surface of a porous material by silk printing or other printing, the mechanical part of the printing device damages the surface of the porous material, but in the present invention, the nozzle does not contact the surface of the porous material. Therefore, the surface of the porous body is not damaged, and the reproduced image is also sharpened in this respect. The liquid ink sprayed on the micropores opening on the surface of the porous material penetrates deep into the micropores at a certain osmotic pressure, flows along the pore surface of the pores by surface tension, and flows further down. The water in the ink evaporates, or the water with less viscous resistance penetrates deeper than the water surrounding the dye, and the black substance in the ink adsorbs on the pore surface. For this reason, the original holes are not blocked by the ink but are formed in finer holes formed by the walls of the light absorbing substance. Such a hole acts as a waveguide for guiding light, so that light penetrates deep into the hole. Due to such penetration of light, a dissolved layer having a thickness of 50 microns or more is formed, and the reproduced image is clearly transferred.

Such point-like ink irradiation is performed by scanning a jet injection printer. This scanning is performed by the relative movement between the nozzle and the porous body in the printer. The jet injection printer can be obtained by a conventional printing means named by Bubble Ink Jet Printer (registered trademark) and its printing power.

The ink is preferably of a dye type, and is a mixed ink of three primary color dyes and is black. The flash light is preferably a Xenon tube discharge light. The discharge of the Xenon tube is white light, which has a large amount of light due to a momentary discharge and is strong and has a wide wavelength range, and therefore has a large amount of absorption into the black ink. If the crushing of holes is insufficient with one flash, it is preferable to irradiate the flash light multiple times. It is conceivable to increase the sharpness of the reproduced image by preheating the printing material before flash irradiation. In this case, the preheating is to keep the temperature just before the melting critical point. Flash light can also be used for preheating. The stamp surface that has gradually accumulated heat is melted with high precision by the last light flash. When a strong light is applied at once, the light energy applied to the local area is excessively diffused, and the resolution of the image is reduced. Irradiation with intense light at one time increases the dissolving area and reduces the resolution. Multiple illuminations The diffusivity of the thermal motion region of the atoms and molecules that form the local part of the stamp surface whose temperature gradually rises due to radiation is low.

The ink that penetrates the pores of cells and capillaries absorbs much light and has heat. The heat dissolves the material of the porous body that melts at a temperature of 100 ° C. or more, particularly around 150 ° C., ie, 200 ° C. or less, and the continuous pores of the melted portion are filled with the melted material and crushed. The melted material penetrates the pores and the melted portion sinks slightly more than the unmelted surface. The depth of the depression does not reach tens of microns.

Apply transfer ink to the porous part of the unmelted surface. This painting, which is preferably done by hand, is free and can be colored. The painted ink permeates into the porous body and is stored in the porous body. The surface tension between the capillary and the ink is high, and no phenomenon has been found in which the ink mixes in the continuous pores. Therefore, a beautiful color image can be reproduced many times from one stamp surface. For example, you can play it tens of times.

Since the stamping material has the physical properties of a porous elastic body (the property of being slightly elastically displaced), this porous body has the function of a pump that pumps ink each time a stamp is applied. Substantially no uneven surface is formed on the stamped surface. On the uneven surface where a clear image is formed on the stamp surface, the boundary between the concave surface and the convex surface is sharp, but the image duplicated by the convex surface is easily deformed on the stamped stand, but loses sharpness. In the present invention, since the stamp surface is substantially flat, even if the stamp is strongly pressed, the image portion of the stamp surface hardly deforms. A certain amount of pressure forces the pores to expand and contract, allowing for a continuous supply of ink. It is preferable that information such as a picture pattern is output from a personal computer, and that the ink is jetted onto the stamp surface by an ink ejection drawing device that ejects a solution such as an ink based on the output signal. Handwritten image is white by optical reading device It can be input to a personal computer as a black image. It is easy to modify and arrange images input to a computer.

Although the ink ejection drawing device, that is, the ink jetting device, is commercially available, it is desired to arrange the ink discharging drawing device to create a new device in which the device is combined with a porous material. A new printer is created that combines a porous body feed mechanism instead of a paper feed mechanism and an ink jet printer. The stencil maker equipped with a porous material feed mechanism takes the feeder out of the setting section one by one and sends it to the scanning moving section, and the ink jetting nozzle located in the feeder section. It consists of an irradiation unit that takes out the original plate and irradiates it with flash, and an extraction unit that takes out the irradiated original plate from this irradiation unit. It is preferable for professional designers to purchase and use such a stencil making machine for personal use, but for children and companies, stencils can be purchased at specialized stores with one stencil maker. In many cases, it is preferable to have a In this case, it is preferable that a system be constructed to send images via telephone lines and have the originals delivered. The exclusive store is equipped with an original plate making machine connected to an image storage device connected to a wired or wireless communication line or an image storage device provided with an input device capable of inputting an original image.

When filling and filling the hole, the amount of deformation of the stamp surface is extremely small. When a hole is crushed, the outline of the drawing is slightly blurred compared to when the hole is closed. In the embodiment described below, it is easier to crush the hole. However, depending on the development of the technology that closes the hole, it is also preferable to crush while closing the hole to take advantage of both the advantages of image clarity and ease of implementation.

According to the stamp formed by the above process, the heat dissolving layer portion is formed on an uneven surface according to observation at a microscope level. It is preferable to form such an uneven surface in the skin layer by flattening it, and it is preferable from the viewpoint of aesthetic appearance, and it is possible to completely eliminate the fine pores in the surface layer. Shape such a skin layer In order to achieve this, a hard transparent solid, for example, a glass plate is pressed against the stamped surface of the porous body to which ink has been sprayed, and the transparent solid is transmitted and irradiated with light.

The information on each two-dimensional plane read by the optical reading device a, is manually input to each of the user terminals AZ.

The stamp making system 2, which receives communications from the user terminal set 1 via a wireless or wired general telephone line, a communication network, or the like, is a sign making room for a specialized contractor producing stamps. It is desirable that the communication between the user terminal collection stand 1 and the stamp making system 2 be bidirectional. In this stamp making room, user's two-dimensional information is displayed. A receiving device 3, a computer 4 having an image processing function, and a stamp making machine 5. Further, it is preferable to include a specialty store-side optical reader 6.

The receiving device 3 includes storage means 7 for storing information on a two-dimensional surface of an individual. The computer 4 retrieves the individual two-dimensional surface information J from the storage means 7 and temporarily stores the information. The ROM 4 sends the two-dimensional surface information J to the stamp making machine 5 to transmit the two-dimensional surface information J. A hardware device 8 with a built-in CPU, which has all the calculation functions necessary to reproduce the information on a stamp board, a keyboard 9 as an input means for operating the R〇M and the hardware device 8 ing. The computer 4 has a display 11 for the operator to check the two-dimensional information J on the plane. The two-dimensional information J sent from the user on paper is input to the storage means 7 by the optical reader 6 at the specialty store.

The stamp making machine 5 includes an X-axis feed mechanism 12 and a Y-axis direction feed mechanism 13.

The X-axis feed mechanism 12 controls the moving distance of the nozzle 14 of the ink jetter. The Y-axis direction feed mechanism 13 includes a belt conveyor 15. The belt conveyor 15 rotates on a transport path that moves in one direction It rolls and its transport path includes a part that moves one-dimensionally in one direction in the Y-axis direction. One point of the belt conveyor 15 stops at the Y-axis machine origin Y0 on the Y-axis set on the machine body 16. The Y-axis mechanical origin Y◦ is relative to the Y-axis program origin set in the hard device 8.

The reciprocating body for operation (to be described later) controlled by the X-axis feed mechanism 12 turns back and forth at the machine origin X〇 on the X-axis set on the machine body 16. The X-axis mechanical origin X O is relative to the X-axis program origin set in the hard device 8. The stamp making machine 5 further includes flash means 1Ί. The flashing means 17 has a cover for covering the front part of the belt conveyor 15.

FIG. 2 shows a stamp plate substrate 18. The stamp plate substrate 18 includes a substrate body 19 and a porous body 21. The substrate body 19 can also be used as a holder for temporarily holding the porous body 21. The substrate main body 19 is made of wood, hard rubber, various types of engineering and plastics, and can be formed in a sponge shape. For the porous body 21 formed in a sponge shape, the following material which is soft but extremely tough against abrasion is used. The porous body 21 is a foam, and has continuous pores formed three-dimensionally in a mesh shape inside. The porous body 21 preferably has continuous pores formed mainly in the thickness direction, that is, in the depth direction. Through the manufacturing process, it is possible to produce a product having pores mainly continuous in the thickness direction. Such open pores are not always open at the surface.

The material of the porous body 21 is preferably a polyolefin-based thermoplastic resin having a melting point of 50 to 150 degrees C. Polyurethane, polyacetal, polyethylene, polypropylene, polystyrene, and polystyrene are preferable. Rear mid etc. can be used It does not need to be elastic.

Ink jitter is known as a conventional means for outputting information on paper and converting it into hard information. The nozzle 14 of the ink jet can jet a constant-speed, constant-quantity liquid ink in a jet state. The ejected ink is a short distance, but during its flight, i.e., before it is ejected from the nozzle and hits the stamp, due to its nozzle shape, surface tension, and air resistance, it has a teardrop shape or an oblong shape. It is formed. That is, the head of the ink is smooth but sharp.

The ink is preferably a dye ink. In particular, it is preferable that it is blackened. For blackening, it is preferable to use red, yellow or green and blue dyes, that is, three primary color dyes. Dyes are, as is well known, a myriad of diazo organic chemicals with double and triple bonds of carbon and nitrogen atoms. Light of a specific wavelength is absorbed from the multiple bonds and is emitted on the contrary on the principle of stimulated emission. Therefore, the light-absorbing substance can permeate the light in the irradiation point region to the depth of the hole. The dye is preferably a water-soluble dye, but even if it contains a small amount of an organic solvent such as alcohol or ethylene glycol, no harm is caused. Specifically, the viscosity of the ink cartridge used in a “Jet Printer” (registered trademark of Bubble Jet Printer ™, for example, manufactured by Canon Inc., Tokyo, Japan) that reproduces information on paper, It is used as a preferred embodiment of the present invention in terms of amount and water content.

The hard device 8 controls the X-axis coordinate X of the nozzle and the Y-axis program coordinate y of the machine origin at which the belt conveyor 15 moves. The nozzle moves substantially continuously, but at a coordinate (x, y), a fixed amount of liquid ink is ejected from the nozzle at a constant speed. This injection may be digitally quantitative. It is not practical to control the amount of each injection. Placed on belt conveyor 15 The surface of the porous body 21 that is stopped at the same position as the belt conveyor 15 receives ink at a constant rate and a constant rate from a nozzle that moves in the X-axis direction at a substantially constant rate. After one reciprocating movement of the nozzle on the X axis, the belt conveyor 15 moves forward by a certain length. Therefore, the coordinate points (X, y) can form a square grid. The porous body 21 of the substrate body 19 receives a black ink on a lattice point.

Figure 3 shows the abstracted ink illumination. The cross-sectional area of the opening of the pores appearing on the surface of the porous body 21 varies in terms of size. If the distribution is shown as holes 22 having an average opening cross-sectional area, they are almost uniformly distributed as shown in FIG. Irradiation traces of ink are formed in a circle 23. Although not shown in the figure, according to the electron micrograph, it is observed that about 100 to 2000 holes belong to one circular region. The average length between the holes is about 30 microns. The center points of the circles shown in Fig. 3 are on a square lattice point, and the diameter of the circle is less than 0.1 mm.

The flash means 17 includes a light emitting source. The light-emitting source is a xenon discharge tube that emits light when a capacitor discharges a high-voltage current instantaneously, and contains xenon gas. The light emitted by the Xenon tube shows a spectrum that extends to the visible region, including the hot-wire region, and appears to the eye as white light. Fig. 4 shows the emission spectrum of a xenon tube designed by a light bulb manufacturer with special specifications in terms of voltage, current, discharge time, and the like. In Fig. 4, the horizontal axis represents wavelength, and the vertical axis represents relative intensity (expressed in%). It extends from the region exceeding 300 nm to the infrared region beyond the visible light region, and appears to the eyes as white light. Such a spectrum can be shown by the light which reacts well with the black-inked chemical substance and causes the chemical substance to violently generate thermal vibration. Equipment embodying plate making machine 5 Is shown. On the base 30, the belt conveyor 15 described above is positioned. The belt conveyor 15 is intermittently rotated by a drive shaft 43 connected to the output shaft of the first servomotor V1 to advance. The front end face of the stamping board 18 placed on the belt conveyor 15 has a different force depending on the type of the stamping board 18 ^ For each type, the Y-axis mechanical origin Y 0 shown in Fig. 1 Is positioned with respect to On both sides of the belt conveyor 15, a draft plate 40 is provided. The stamp plate substrate 18 is guided by the guide plate 40 and moves substantially in parallel and goes straight.

The ink jet 41 is a conventional means, and includes a scanning reciprocating body 42 and the nozzle 14 described above. The scanning reciprocating body 42 is driven by an endless belt 42 a that reciprocates. The nozzle 14 is fixed and held with respect to the scanning reciprocating body 42. The scanning reciprocating body 42 includes, in addition to the nozzle 14, an ink tank, a thin ink supply pipe, and a ceramic heater for instantaneously increasing the temperature of a part of the ink supply pipe. Have. A part of the ink in the ink supply pipe is locally heated by the ceramic heater and is instantaneously vaporized, and the ink in front of the ceramic heater is instantaneous due to the vapor pressure of the vaporized vapor. The nozzle speed is increased and a certain amount of ink is discharged from the nozzle (ink between the ceramic nozzle and the tip of the nozzle). As the ink jet of such an injection mechanism, a well-known and commonly used technique used for printing under a trade mark such as a bubble jet is used as it is.

The scanning reciprocating body 42 is driven by the second servo motor V2 via the endless belt 42a. The second servomotor V2 and the scanning reciprocating body 42 constitute the X-axis feed mechanism 12 described above. 1st servo V1 and belt conveyor 15 force The Y-axis feed mechanism 13 described above is configured. The front part of the belt conveyor 15 is covered with a casing cover 45. A xenon discharge tube 46 is provided in the casing cover 45. A reflecting mirror 48 having a cylindrical reflective curved surface 47 calculated by calculation is provided above the xenon discharge tube 46. Xenon gas and other gases are sealed inside the xenon discharge tube 46. The xenon discharge tube 46 emits a large amount of flash light due to the high-voltage multi-current that the high-voltage capacitor discharges instantaneously.

The emitted light is reflected by the lower surface of the reflecting mirror 48, and illuminates the surface of the porous body 21 of the lower printing substrate 18 with substantially uniform light intensity. It is preferable to perform such irradiation after changing the stop position of the stamp plate substrate 18 with the belt conveyor 15. Belt conveyor 15 extends through the casing cover 45. From the front end of the belt conveyor 15, the sign board 18 to which the image has been transferred is taken out. A gap having a constant width is provided between the nozzle 14 and the surface of the porous body 21. The nozzle 14 is scanned without damaging the surface of the porous body 21.

FIG. 7 is a drawing in which the state where the surface of the porous body 21 is irradiated with the ink by the ink jetter 41 is abstracted from a photograph taken by enlarging with an electron microscope. The lump of ink 50 discharged from the nozzle 14 by the high-pressure steam flies in the air in a tear state and collides with the coordinate point P (x, y) on the surface of the porous body 21. The hatched portion is the portion of the solid that forms the pores of the porous body 21. Immediately after the moment of the collision, a part of the ink of the ink irradiation section 51 diffuses on the surface of the porous body 21 and has a thin swell. The ridges are almost uniformly diffused in the circular region of the circular portion 23 shown in FIG. A part of the ink penetrates about 10 to 30 micron near the entrance of the micropore to form a submerged layer 52. Immediately after the ink irradiation, water lower than the viscosity of the entire ink before irradiation oozes out of the submerged layer 52, and furthermore. The water infiltrates 200 micron deeper and forms a water infiltration layer 53. The jetted jetted black ink penetrates into the micropores at a sufficient speed and dive deeply into the hole. This speed promotes the penetration of viscous ink. The amount of ink in the upper portion and in one irradiation area of the submerged layer 52 is controlled with high precision by the ink jetting, and has a preferable constant amount.

The water of the ink component that has penetrated into the micropores has a lower viscous resistance than the water surrounding the light-absorbing substance, which is the ink component, and thus flows more smoothly on the wall surfaces of the micropores, and the micropores flow. Shows a tendency to penetrate deeper into Water that penetrates deeper into such water will lead to higher concentration ink sections. As shown in Fig. 8, the high-concentration portion of the ink penetrates deeper into the pores as a result of being pulled by the leading water, and further progresses along the wall surface of the micropores with surface tension, and the high-concentration ink that adheres to the wall surface The portion again forms micropores of smaller cross-sectional area, which again open on the original surface of the porous body. FIG. 9 shows a state after irradiating the porous body 21 of FIG. 7 with flash light. The submerged layer 52 in FIG. 7 absorbs flash light well and melts when the temperature rises to 100 ° C. or higher, and in reality, 150 ° C. to 200 ° C. The dissolved porous body material further penetrates the micropores and solidifies again to form a re-solidified layer 54. Due to such dissolution and re-entry, a part of the surface layer of the porous body 21 is depressed to form a depressed portion 55. The micropores 56 in the depressions 55 are filled or crushed by the re-solidification layer 54 and the openings disappear. The water in the water infiltration layer 52 rises to near the temperature, evaporates, and disappears from the pores. The re-solidification layer 54 is formed almost to the point where the irradiation light has penetrated into the ink layer.

The depth of this depression is about 10 micron. The original surface 57 which is not depressed is colored with a marking pen. The color ink may be a dye ink or a pigment ink. Color ink is applied to the fine pores on the original surface. Tension · Penetrates deeply by capillary action to form a permeation layer 58. When such a stamped surface 59 is pressed against the paper surface, both the surface of the depression and the original surface 57 may substantially contact the paper surface, but there is substantially no deformation of the boundary line of the depression. The force link retained in the microholes on the original surface 57 is transferred to the paper. By such a transfer, a strict transfer is performed such that the person's face image can be determined.

Figure 10 shows that the light wave irradiating the reopened micropore penetrates deeper into the micropore as a waveguide, and is absorbed more by the ink component attached to the wall surface of the micropore. This shows a state in which a larger amount of the porous body is dissolved to form a re-solidified layer 54 reaching a thickness of 50 micron. With such a re-solidification layer 54, the micropores are more completely closed.

The hardware device 8 can easily reverse the negative / positive value of the coordinates of the two-dimensional development by operating from the keyboard 9, thereby facilitating image correction. By forming both the negative and positive transfer images on the porous body 21, it is possible to form a colorless image in which the ground color does not appear. At the time of monochromatic image reproduction, the transfer ink can be injected from the back side of the porous body 21. In this case, the number of transfers can be increased.

FIGS. 11 and 12 are flowcharts for operation of the automatic stamp making machine. When an order signal from the user reaches the receiving means 3 (step 1), the reception port of the receiving means 3 is opened (step 2), and the user information and the ordered 2D image information J are stored in the storage unit. It is stored (steps S3 and S4). If there is no order signal (step S5), the stamp making switch is entered from the keyboard 9 and the operation of the hard means 8 is started (step S6). The data of the stamp plate is manually input to the hard means 9 by giving priority to either the keyboard 9 or the data stored in the storage unit (step S7). At the time of inputting the stamp size, the two-dimensional coordinate values (X, Y) of the nozzle 14 of the ink jet 41 are input, and the following initial values s and k are reset to zero, and the following step is performed. The number of times M and the number N of digitized coordinate points described below are automatically set in conjunction with the size input. The fixed point fixed on the conveyor 15 returns to the origin in the Y-axis direction (step S8). Next, the stamp plate substrate is placed at a predetermined position on the conveyor 15 by any means not described in this specification (step S9). This means includes a human means for placing the board by hand, with the front edge of the board for the sign board being manually aligned with the mark line drawn on the conveyor 15 in the X-axis direction.

Step S I1 to Step S 17 show a two-dimensional drawing process by Inkjets. Ink is sprayed onto the coordinate points (X [k, s], Y [k, s]) in the coordinate system fixed and set on the base 31 with respect to the stamp plate substrate. The X axis is divided into N equal points, divided into N points. S is initially 0 with conveyor 15 stopped. k varies from 1 to N. According to the number of k, whether or not the ink jet nozzle 14 ejects ink has already been input to the hard means in step S7 as data.

^> o

An ink is jetted onto the coordinate point (X [k, 1], Y [k, 1]) (step S11). The value of s is incremented by 1 (step S13), and when s reaches the value N (step S14), the conveyor 15 advances by a fixed minute distance (step S15). k is incremented by 1 (step S16), steps S11 to S16 are repeated, and when k reaches the value M (step S17), the conveyor 15 moves forward by a certain distance. Then, it stops at the irradiation section (step S18). Next, the xenon tube 46 is discharged (step S19). The conveyor 15 moves forward (step S20), and the ink spraying is completed, and the stamp board is taken out. Conveyor 15 moves forward and completes or retreats Returns to the machine origin and waits for the next stamp plate creation.

The stamp plate making machine described above is a stamp plate created by receiving light irradiation from an introduction portion (in the above description, a region where a substrate is placed on a conveyor by human means) for guiding a stamp plate original plate. The transport path to the plate lead-out section is formed continuously, and along the way, the moving placement section, the stop / step section (ink irradiation section which is an intermittent moving section), and the transfer from the ink irradiation section to the light irradiation section An extraction unit is provided to take out the completed stamp from the transfer unit and the ink irradiation unit, and an automated or semi-automated system that can create stamps fully automatically has been constructed.

Until the prices are reduced so that they can be owned by individuals, these devices will be located at bases nationwide, and will receive personal images by personal computer communication and send completed stamps by mail or other means. This can expand the range of artists' activities. At the stand where the order was received at the store, the image brought by the customer is input to the storage unit by the optical reader 6 at the specialty store.

The stamp can also be provided without the substrate 19. The stamp plate can be made cylindrical. This platform is suitable for repeatedly creating images because the same image can be repeatedly transferred at equal intervals. The above-mentioned substance is selected as the porous body used in the present invention. The porous body is softer than the rubber material used for the rubber stamp, but is much less likely to be worn and durable. If worn over a long period of time, a stamp plate with almost the same image can be made, so it can be used permanently. The resolution of the image is high, and the reproduced image is much clearer than a rubber stamp, so that the human face can be distinguished. By using a water-based ink as the transfer ink, it is possible to wash with water. It is also possible to spray the transfer ink by ink jet. When the transfer ink is applied to the surface of the porous body by handwriting, a blurred image can be reproduced according to the skill of the individual. Depending on how they are painted, the work can be further creative. Industrial applicability

The stamp plate according to the present invention is suitable for prints freely created according to personal preference. Furthermore, it can be used as a seal, a seal, and a stamp. In this case, it is convenient to provide an ink tank on the back side of the porous body. It can also be used as a seal to create personal business cards and letter forms. It is also suitable for a rotary press part of a printing press.
