Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention enables printing even on a printing material whose printing surface has a shape other than a flat surface, for example, a three-dimensional curved surface. , a printing device, and a method of manufacturing and using the same.

[Prior Art] Printing on a printing material such as a golf ball whose printing surface has a shape other than a flat surface, such as a three-dimensional curved surface, is generally performed by:
A vat printing method is used that uses a specially shaped vat that adapts to the printing surface.

This vat printing method is a method in which the ink supplied to the first plate is transferred onto the printing surface of the printing material using a transfer medium called a vat. A plate is formed, ink is supplied to the recessed image area on the plate, and then a batt is pressed against the image area of the plate to adhere the ink of the image area to the batt, and the batt is applied to the printing substrate of the printing material. By pressing it against the surface, the ink adhering to the vat is transferred to the surface to be printed.

The plate member used in this case is a hard base member made of stainless steel or the like that is coated with an ultraviolet curable resin film, and images such as one character and one figure are formed on the ultraviolet curable resin film. The part of the UV-curable resin film corresponding to the image area of the part of the part is removed by placing the part of the part in close contact with each other and irradiating ultraviolet rays from the top of the part of the part of the part. It is formed by etching.

In addition, the supply of ink to the recessed image area of the plate is as follows:
This is done by supplying ink to the entire surface of the plate using an ink plate, and then removing unnecessary ink from the plate using a doctor blade.

[Problems to be Solved by the Invention] However, in the case of the above-mentioned vat printing method, the plate used here requires etching treatment, which requires equipment (etching equipment) to create the plate, and this To print using a plate, you need an ink plate and a doctor blade to supply ink to the image area of the first plate, a device to operate it, and a device to operate the ink plate and the image part of the plate. Since various equipment such as a vat for transferring the image onto the printing surface and a device for operating the vat are required, the printing apparatus becomes large-scale and can only be operated by a skilled person.

This invention was made in view of the above circumstances,
The purpose of this is that it does not require any special facilities or equipment to create a single plate, and it also allows for the supply of ink to the image area of the plate and the transfer of the ink to the printing surface of the printing material. It is possible to configure a printing device capable of printing even a printing material whose printing surface has a shape other than a flat surface without requiring special equipment, and which requires skill. An object of the present invention is to provide a printing device that can be easily handled without any hassle, and a method for manufacturing and using the same.

[Means for Solving the Problems] In order to achieve the above object, the printing device of the present invention includes an open-cell sponge member housed in a case, a character coated on the outer surface of the open-cell sponge member, and a character formed by a through hole. , a photoreactive resin film on which an image area such as a figure is formed, and a transfer ink impregnated into the open cell sponge member.

Further, in the method for manufacturing a printing device of the present invention, one surface of an open-cell sponge member is coated with a photoreactive resin film, and a printing plate on which images such as characters and figures are formed is tightly attached to the photoreactive resin film. Then, a light beam is irradiated from the upper part of the block, and the light rays alter the quality of the photoreactive resin film portion corresponding to the image of the block or the part of the photoreactive resin film that does not correspond to the image of the block. After removing the portion corresponding to the image on the printing plate, the open cell sponge member is housed in a case, and transfer ink is injected into the open cell sponge member.

Furthermore, the method of using the printing apparatus of the present invention includes an open-cell sponge member housed in a case, and a photoreactive material coated on the outer surface of the open-cell sponge member, in which images such as letters and figures are formed by through holes. Compressing the open cell sponge member by pressing the photoreactive resin film of a printing device comprising a photoreactive resin film and a transfer ink impregnated into the open cell sponge member against the printing surface of the printing object. The transfer ink that oozes out from the through holes of the photoreactive resin film is applied to the printing surface of the printing material.

[Sakukawa] According to the printing apparatus of the present invention configured as described above, the plate member is composed of an open-cell sponge member and a photoreactive resin film coated on one surface of the open-cell sponge member. Therefore, a plate is formed by simply placing a block with images such as letters and figures formed on the photoreactive resin film and irradiating light from a camera flash lamp or the like from the top of the block. be able to. Therefore, no special equipment is required to create the plate, and the photoreactive resin film is thin and flexible, and can be freely deformed by the slight pressure of the open-cell sponge member. When the film is pressed together with an open-cell sponge member onto the printing surface of the printing material, the photoreactive resin film responds to even slight changes in the shape of the printing material and becomes in close contact with the printing surface.
The transfer ink impregnated into the compressed open-cell sponge member oozes out from the through holes (image area) of the photoreactive resin film and is attached (transferred) to the printing surface. Even when printing on a printing material, no special equipment is required to supply transfer ink to the image area of the plate or to transfer the transfer ink to the printing material. It is simple and can be easily handled without requiring any skill.

[Embodiment J] Hereinafter, an embodiment of the present invention will be described in detail based on the drawings.

First Embodiment> Figure t51 is a sectional view showing a printing apparatus according to a first embodiment.

This printing device consists of a top-opening case l made of synthetic resin or the like, and a plate 2 fitted and housed in this case l. It consists of a photoreactive resin skin WJ4 that is adhered to the upper surface of the member 3 and has an image 5 such as a character or a figure formed through a through hole. The photoreactive resin film 4 contains light!
A material whose quality is altered by radiation and whose image-corresponding portion can be removed is used, and examples of this type of material include ultraviolet curing resins and low-humidity heat-melting resin films.

Further, the open-cell sponge member 3 is impregnated with colored transfer ink.

The printing apparatus having the above configuration produces a plate 2 using a plate member which also includes an open cell sponge member 3 and a photoreactive resin coating 4, and then attaches the open cell sponge member 3 of the plate 2 with the photoreactive resin coating 1194 on top. Store it in the case l toward
Thereafter, the open-cell sponge member 3 is manufactured by injecting transfer ink. In this case, the plate 2 is manufactured through the steps shown in FIGS. 4 and f55. First, Figure 4 (a
) and as shown in FIG.
8 is transferred to produce block version 9. In this case, as shown in FIG. 5, the lettering sheet 6 is made of letters 6a made of carbon ink on the back side of a transparent base film through a release layer.
The ink image forming surface is brought into close contact with the upper surface of the transparent sheet 7, and the character 6a is printed on the transparent sheet 7 by rubbing the surface side of the base film with a thin and relatively hard member such as a pen or stick. Transfer on top. This results in 1
As shown in Figure 4(C), in the 0th order where the proof 9 is manufactured,
Photoreactive s+ on one surface (upper surface) of the open cell sponge member 3
This photoreactive resin coating rQA is coated with n'n coating 1124.
A printing plate 9 is brought into close contact with the printing plate 9, and a light beam 10 is irradiated from above the printing plate 9 using, for example, a flash lamp (such as a xenon lamp) of a camera to alter a predetermined portion of the photoreactive resin film 4. In this case, if the photoreactive resin film 4 is a low-temperature heat-melting resin film, the printing plate 9 is inverted as shown in the figure and brought into close contact with the photoreactive resin film 4 and irradiated with infrared rays. Letters aail made of carbon ink
1 minute absorbs light heat, and the part corresponding to this part melts (
as shown in Fig. 4(d).

An image 5 is formed by the through holes. In addition, when the photoreactive resin film 4 is an ultraviolet curable resin, as shown in FIG. When irradiated for a period of time, the portions of the block 9 that do not correspond to the characters 6a are hardened (changed in quality), and the portions corresponding to the characters 6a remain uncured because the light beam 1O is blocked. This uncured portion can be easily removed by water treatment or the like, and by removing this uncured portion, an image 5 of through holes is formed in the photoreactive resin film 4.

In addition, although the case where the block copy 9 in FIG. 4 was produced using the lettering sheet 6 was shown, as shown in FIG.
It is also possible to create a block copy 9 by writing images 8 such as letters and figures directly on it, or by printing images such as letters and figures using a thermal ink sheet such as a word processor. It is. FIG. 6(b) shows the state in which the printing plate 9 is brought into close contact with the photoreactive resin coating 4 of the printing plate member consisting of the open-cell sponge member 3 and the photoreactive resin coating 4 (see FIG. 4). (equivalent to (C)).

Next, a method of using the above printing apparatus will be described.

FIG. 2 shows a case where printing is applied to a spherical member 12 such as a golf ball whose printing surface 12a has a three-dimensionally curved shape. In this case, the spherical member 12 is attached to the printing surface 12.
It is pressed against the photoreactive resin film 4 so that a is facing the image 5 of the plate 2 (in the direction of the arrow a), and in this state, it is horizontally moved in the directions of the arrows A and C. In this way, the open cell sponge member 3 is compressed according to the shape of the printing surface 12a by pressing the spherical member 12, and as a result, the transfer ink impregnated in the open cell sponge member 3 forms a photoreactive resin film. It oozes out from the through hole 4 and adheres to the printing surface 12a. In this case, the photoreactive resin film 4 is thin and flexible, and can be freely deformed even by slight pressure from the open-cell sponge member 3, so that the spherical member 12 has small and deep dimples 12c like a golf ball. Even in the case where the photoreactive resin skin 114 is pressed by the open-cell sponge member 3, it comes into close contact with the bottom surface of each dimple 12c, and the transfer ink is accurately transferred into the dimple 12c as well. Third
The figure shows transfer ink 15 seeping out from the through hole on the printing surface 1.
The spherical member 12 is shown attached to 2a.

<Second Embodiment> FIGS. 7 and 8 show a printing apparatus according to a second embodiment.

In this printing device, when printing on a spherical member 12 whose printing surface 12a is a three-dimensional curved surface, the case 1 is devised so that printing can be performed by moving the spherical member 12 while rolling it. This is what I did. That is, the case 1 of this printing apparatus has a rectangular parallelepiped shape, and a guide groove 13 is formed along the longitudinal direction in the center of the upper surface. The guide groove 13 has a width that is approximately the same as the diameter of the spherical member 12 and a depth that allows the spherical member 12 to be sufficiently guided. In addition, the bottom surface 13 of the guide groove 13
a has a curved shape that follows the shape of the spherical member 12. A plate storage recess 14 is formed in the bottom surface 13a of the guide groove 13 in the center of the case 1, and this plate storage recess ll61
4, the open cell sponge member 3 of the plate 2 is fitted and housed. In this case, the photoreactive resin film 4 is
In such printing III, one spherical member 12 is fitted into the guide groove 13 of the case 1, and the guide groove 13 is pressed with a predetermined pressure. When the spherical member 1 is moved in the direction e along the guide groove 13 while being rotated while being pressed against the bottom surface 13a of the spherical member 1
The transfer ink impregnated into the open-cell sponge member 3 is applied to the printing surface 12a of 2 as a photoreactive resin skin! It oozes out from the through holes 14 and adheres to the printing surface 12a as shown in FIG.

In this case, when the spherical member f2 moves onto the plate z, the photoreactive resin film 4 comes into close contact with the printing surface 12a due to the pressing of the spherical upper member 12, and the open-cell sponge member 3 is compressed, thereby preventing the transfer. Ink oozes out from the through hole. Further, the pressing force of the spherical member 12 is applied to the guide groove 13.
Since the transfer ink is set at the bottom surface 13a of the through hole, there is no need for excessive or insufficient pressing pressure, and an appropriate amount of transfer ink oozes out from the through hole.

Third embodiment> FIG. 9 shows a printing apparatus according to a third embodiment.

In this printing device, a spherical member 12 is fixed, and the spherical member 12 is formed on the upper surface of a jig 16 so that printing can be performed by moving the plate 2 relative to the fixed spherical member 12. It is fitted and housed in a cylindrical deep hole 16a. In this case, the deep hole lea has a diameter that is substantially the same as the diameter of the spherical member 12, and its bottom surface 16b is curved along the shape of the spherical member 12.

The bottom surface 16b has a central portion open to the lower surface of the jig 16 so that the spherical member 12 comes into contact with a portion of the bottom surface 16b. At the top of the deep hole lea of such a jig 16, there is a plate 2 on the bottom side.
A cylindrical case 1 housing an open-cell sponge member 3 is fitted in a vertically slidable and removable manner. This case 1 is slid by a knob la provided at the center of the upper end, but when the flange 1b formed at the upper part comes into contact with the upper end surface lee of the jig 16, the sliding is limited to a lower limit. The plate 2 fitted and stored in the plate storage recess 1c formed on the bottom side of the case 1 has a spherical shape, and its photoreactive resin skin $4 is curved into a curved surface that follows the shape of the spherical member 12. are doing. In this case, when the flange 1b of the case l sliding in the deep hole lea comes into contact with the upper end surface 16c of the jig 1b, the photoreactive resin coating lI
4. The printing surface 12a of the spherical member 12 is brought into close contact with the printing surface 12a under a predetermined pressure.

In the printing apparatus configured in this manner, the spherical member 12 is fitted and stored in the deep hole 16a of the jig ld from which the case 1 has been removed, and then the case 1 is fitted into the deep hole lea of the jig 16 and the Slide it downward with knob 1a,
The photoreactive resin coating 4 of the plate 2 is brought into close contact with the printing surface 12a of the spherical member 12 until the flange 1b comes into contact with the upper end surface 16c of the jig 16. In this way, as the open-cell sponge member 3 is compressed, the ink impregnated in the open-cell sponge member 3 oozes out from the through-holes of the photoreactive resin film 4, and as shown in FIG. 12a.

The printing apparatus of the present invention can be used not only for the spherical member 12 such as a golf pole where the surface to be printed has a three-dimensional curved surface as shown in the embodiment, but also for the surface to be printed which has a flat shape or the like. It can be used as a printing device for any printing material.
