The present invention relates to a structure of a plate making apparatus for forming a portion and a non-ink bleeding portion for a non-image portion.

[0002]

2. Description of the Related Art Conventionally, various printing apparatuses such as stamps have been used to print desired images such as pictures and characters on a print medium such as a postcard. Of these, Japanese Patent Laid-Open No. 7-2
In Japanese Patent No. 85258, a stamped surface composed of an ink exuding portion which becomes a mirror image of a desired imprint original and an ink non-exuding portion which closes the continuous bubbles is formed on the surface of a sheet having open cells and impregnated with stamp ink. A method of manufacturing a multicolor stamp has been proposed in which a printing plate is used, a plurality of colors of ink are directly sucked into an ink exuding portion of the printing plate, and a printing medium such as a postcard is pressed against the printing plate surface for printing. .

In the above publication, as a first method for manufacturing (plate making) a printing plate having a printing surface formed of an ink bleeding portion which is a mirror image of a predetermined imprint document and a non-ink bleeding portion which closes open cells, is provided. A thermal transfer sheet is superimposed on the surface of a material sheet (porous sheet) which has open cells and can be impregnated with stamp ink, and an original sheet having a desired imprint is superimposed thereon so as to be a mirror image, and the material sheet is compressed. By irradiating infrared rays from above the original sheet in this state, a transfer portion and a non-transfer portion of the heat transferable ink are formed on the surface of the material sheet, the transfer portion becomes a non-ink bleed portion, and the non-transfer portion becomes a bleed ink It is disclosed to have a stamped surface as a part.

[0004] In a second method, a heating plate made of at least one selected from the group consisting of carbon and a polymer substance is placed on the surface of a material sheet having open cells and impregnated with stamp ink, Further, by impregnating a hard-to-evaporate substance into a document sheet having a desired imprint made of a liquid-absorbing opaque sheet so that the imprint document image becomes a mirror image, and then irradiating a flash containing infrared rays from the document sheet side However, the heating plate corresponding to the portion other than the imprint original image generates heat and melts the surface of the material sheet to form an ink non-exuding portion, while the surface of the material sheet corresponding to the imprint original image does not melt and forms an ink exuding portion. It is disclosed to have a stamped surface.

In these plate making methods, an original sheet is placed on a support plate such as an acrylic transparent plate on the light irradiation side, and then a thermal transfer sheet or a heating plate is stacked thereon.
Further, a porous sheet is superimposed on the porous sheet, and a pressing force is applied to a portion above the porous sheet so that a flash is emitted from the support plate side.

[0006]

However, when light is radiated in an environment where the room temperature is low, such as in winter, a considerable portion of the radiated light energy is consumed for raising the temperature of other members and air. As a result, sufficient heat energy cannot be applied to the thermal transfer sheet or the heating plate, and as a result, heat generation at portions corresponding to portions other than the imprint original image on the surface of the porous sheet becomes insufficient. , The surface of the material sheet is incompletely melted, and the boundary between the ink non-exuding portion and the ink exuding portion becomes unclear, resulting in poor plate making;
There is a problem that the porous sheet is wasted.

Further, in the flash operation by the flash valve of the prior art, the light energy to be irradiated becomes uneven due to the variation of the charging capacity and the discharge time thereof, and the plate making result also becomes uneven, and a good plate making is performed. There was a problem that it could not be formed reliably. The present invention has been made in order to solve these problems of the related art, and has as its object to provide a plate making apparatus capable of reliably performing good plate making.

When the intermediate lid 9 is disposed on the upper surface of the inner lid 10, a press bulging portion 28 for uniformly pressing the upper surface of the inner lid 10 at a plurality of locations is formed integrally. A handle 29 is provided on the outer surface of the outer cover 8, and a hook 31 for engaging and disengaging with a hole-shaped engaging portion 30 of the case 4 is provided on a free end side of the outer surface of the outer cover 8.

Further, the outer lid 8 is formed with at least two pressing bulges 33 for pressing the intermediate lid 9 substantially uniformly when the outer lid 8 is overlaid on the upper surface of the intermediate lid 9.

In the case 4, as shown in FIG. 4, a CPU 45 which is a microcomputer-type control device as control means for controlling the operation of the light source 14 is provided.
Is provided, and the RO storing the control program is provided.

Instead of the microcomputer type control device, a control device having a combination of predetermined electric circuits may be used. Next, the configuration of the stamp substrate 25 of the present invention and a plate making method using the same will be described in detail. The stamping substrate 25 of the first embodiment has open cells and contains carbon black or a light energy-absorbing substance dispersed in a porous material that can be impregnated with stamp ink. The material is a foamed resin material such as a polyolefin-based resin, a polyvinyl chloride-based resin, and a polyurethane-based resin, and preferably has flexibility (softness) when formed into a porous sheet. Therefore, open pores are exposed over the entire surface of at least the wide surface 25a of the stamp substrate 25 before plate making (see FIG. 5A).

It is also possible to use a rubber-based material. The thickness of the stamp substrate 25 is about 1 mm to 5 mm. As described above, when the surface side of the stamp substrate 25 of this type is irradiated with light, it is heated and melted to close the pores exposed on the surface by containing the carbon black or the light energy attracting substance. It will have properties. Then, in the compressed state, the stamp substrate 25
After the surface side is melted, the pores that are solidified and exposed on the surface are closed and become ink non-exuding portions, and the undissolved portions become ink exuding portions where the pores are exposed on the surface.

In the examples, the weight ratio of the carbon black or the light energy-absorbing substance contained is such that the content ratio of the carbon black to the polyurethane foamed resin is 1.
0% to 1.5% by weight. The content of carbon black is not limited to the above, but may be 0.1% by weight.
It may be in the range of ~ 15% by weight. If the content of carbon black is larger than 15% by weight, the stamp substrate 25 itself becomes black, and it becomes impossible to know the color of the applied stamp ink, and it is also impossible to know whether or not the stamp ink has been applied. If it is less than 0.1% by weight, sufficient heat generation cannot be obtained.
There is a problem that the surface of the stamp substrate 25 cannot be melted.

Further, as the light energy attracting substance,
There are silver chloride and silver bromide. At the time of plate making, PPC paper (manuscript paper for tracing) is used as the manuscript sheet 26 in advance.
Draw a light-impermeable image portion 21 on the surface of a light-transmissive paper such as black, white, gold, silver or the like with light-opaque ink, oily marker, paint, paint, or the like. .

On the other hand, a transparent sheet 22 to be interposed between the original sheet 26 and the wide lower surface 25a of the stamp substrate 25 is prepared. The transparent sheet 22 has a melting point of the stamp substrate 25 (about 7 in the case of a soft polyurethane resin).
(0 ° C., about 120 ° C. in the case of a soft polyolefin-based resin). As an example, transparent PE having a high melting point (about 230 ° C.)
T (polyethylene terephthalate) resin film is preferable, and the thickness of each sheet is about 0.025 mm to 0.2 mm.

Next, the original sheet 26 is placed on the transparent plate 11 so that the image area 21 faces up, and then the transparent sheet 22 is overlaid. The layers are stacked such that the exposed side faces downward (see FIG. 5B). Further, when the inner lid 10, the intermediate lid 9, and the outer lid 8 are sequentially stacked and the operator applies a predetermined pressing force to lock the hook 31 to the engaging portion 30, the operation switch provided on the engaging portion 30 is provided. 50 is turned on, the light source body 14 is continuously turned on, and movement starts.

In the present embodiment, the main heating operation is performed after performing the preliminary heating about once or twice, and
During the preheating operation, the power supply circuit 53 changes the voltage supplied to the light source 14 to a second voltage (reference voltage) described later.
The light source body 14 is set to a state where it is lowered by about 10% to 50%
Is turned on, and at the time of the main heating operation, the light source 14 is turned on in a state of being raised to the second voltage as the reference voltage.

For example, when the light source body 14 is located at the left end in FIG.
First, the light source body 14 moves at a constant speed in the direction of arrow A in FIG. 1 while being continuously lit, performs preheating, and comes into contact with the second limit switch 49 to be turned ON to raise the reference voltage (second voltage). The main body is heated by moving the light source body 14 in the direction of arrow B in FIG. 1 at a constant speed, and when the light source body 14 comes into contact with the first limit switch 48, the light is turned off and the movement is stopped.
The prepress operation is completed. Note that the number of times of preheating may be plural.

In this way, the air and other components in the case 4, the transparent plate 11, the original sheet 26, and the stamp substrate 25 can be heated to some extent by the preheating operation. Then, the plate-making operation described later can be reliably performed by the main heating operation. That is, light energy that has passed through a portion (non-image portion) other than the image portion 21 of the original sheet 26 passes through the transparent sheet 22 as it is (see FIG. 5C), and the light energy is used as the light energy. The carbon black near the surface (light irradiation side surface) corresponding to a portion (non-image portion) other than the image portion 21 absorbs heat, and a portion of the stamp substrate 25 other than the image portion 21 (non-image portion). The portion corresponding to the portion (a) is heated and melted, and then solidified, whereby pores on the surface are closed, and an ink non-leached portion 23a having a predetermined thickness is formed (see FIGS. 5 (d) and 6).

On the other hand, the original sheet 26 is
When is black containing carbon, the image area 21 is heated by light energy irradiated from the transparent plate 11 direction,
Although the temperature rises, the transparent sheet 22 corresponding to the image area 21 conducts heat in a lateral direction or the like within the thickness of the sheet.
In other words, the heat generated on the original sheet 26 side is absorbed and dispersed by the transparent sheet 22, and the surface portion of the stamp substrate 25 corresponding to the image area 21 is not heated, and the shape of the image area 21 is not heated. The ink bleeding part 24 with the pores exposed to
Becomes When the image portion 21 is other than black,
The light energy is cut off and reflected by the image portion 21, and the surface portion of the stamp substrate 25 corresponding to the image portion 21 is not heated and becomes the ink exudation portion 24 in which the pores are exposed.

Therefore, when the transparent sheet 22 and the original sheet 26 are removed from the wide surface 25a of the stamp substrate 25 after the light irradiation, the image on the original sheet 26 is removed as shown in FIGS. The ink bleeding portion 24 remains with the pores in the shape of the mirror image of the line portion 21 exposed,
The ink non-bleeding portion 23a corresponding to the non-image portion can be made as a stamp S having a predetermined stamped surface formed on the wide surface 25a of the stamp substrate 25.

In addition, depending on the magnitude of the pressing force against the stamp substrate 25, in other words, depending on the degree of adhesion between the stamp substrate 25 and the document sheet 26, for example, the bending at substantially the center of the transparent plate 11 in the longitudinal direction. If the moving speed of the light source 14 at a position where the height is large is controlled to be reduced, the stamp substrate 25
There is an effect that the performance of the stamp surface that can be formed on the entire surface can be made uniform throughout.

Preferably, the transparent sheet 22 is formed by sandblasting or finely embossing or embossing the surface of the transparent sheet 22 and the stamp substrate 25 to make contact with the wide surface of the stamp substrate 25. When a thin insulated air layer is formed between the transparent sheet 22 and the image area 21 of the original sheet is black ink, the heat generated in the image area 21 is efficiently absorbed and dispersed by the transparent sheet 22, Since the light is not transmitted in the direction of the surface of the stamp substrate 25, the pores in the shape of the mirror image of the image portion 21 remain exposed, and the effect of imprinting the edge of the imprint of the ink exudation portion 24 is achieved.

In another embodiment, the stamp substrate 2
5 is a porous sheet which does not contain carbon black or a light energy-absorbing substance, has open cells, and can be impregnated with stamp ink, and is made of the same material as described above. In this case, as the heating sheet that comes into contact with the wide surface (the surface where the pores are exposed) of the stamp substrate 25, a black pigment such as carbon black is mixed in advance or printed on the surface. In this embodiment, in the main heating operation, light irradiated from the transparent plate 11 side passes through the original sheet 26, and at a portion corresponding to the non-image portion, the light is heated by the light energy absorbed by the black heating sheet, Since the surface of the stamping substrate 25 facing the surface is once melted and solidified by the heat, the stamping ink becomes an ink non-exuding portion 23a in which the ink does not exude, and at a portion corresponding to the image portion 21, the light does not transmit.
The ink bleeding portion 24 remains with the pores in the original sheet 26 in the shape of the mirror image of the image portion 21 exposed, and the non-ink bleeding portion 23a corresponding to the non-image portion forms the stamp substrate 2
5 can be made as a stamp S having a predetermined stamped surface which is formed on the wide surface 5 and is a mirror image of the image area 21.

Next, the configuration of the printing unit 3 will be described.
The preprinted stamp S is placed face down on a support table or the like on the upper surface of the bottomed case 7 removed from the case 4 and the back side of the prepressed stamp S (opposite the stamped surface). After affixing a double-sided adhesive tape (not shown) to both ends of the bottom case 7 and rolling and moving the pressing roller (not shown) taken out from the pressing roller holder on one side of the bottomed case 7 as well, The back surface of the stamp S is wound around and fixed to the peripheral surface of the pressing roller. Next, ink of a predetermined color is sucked into the ink bleeding portion 24 corresponding to the image portion of the stamp S, and the ink attached to the ink non-bleeding portion 23a is wiped off. (Not shown)
Is placed on the sheet, and the sheet is rolled while being pressed by the pressing roller with handle, so that printing on the sheet can be completed. In addition, it is a matter of course that a multicolor printing stamp is obtained by injecting another color of stamp ink into another portion of the ink exudation portion 24.

Since the reflector 13 is attached to the light source 14, strong light energy is applied only to the vicinity of the surface of the stamp substrate 25 facing the position where the light source 14 moves. It is possible to improve the uniformity of the performance of the stamp surface by the preliminary heating by the lighting operation of No. 14 and the main heating. Further, in the short width direction having a dimension orthogonal to the longitudinal direction of the stamp substrate 25, it is considered that the fluctuation (deviation) of the pressing force is small.
If the reflector 13 is formed in the longitudinal direction in a direction orthogonal to the longitudinal direction of the stamp substrate 25, the stamp substrate 25
Along the width direction, the light source body 14 and the reflector 13 can receive substantially uniform light irradiation, and the control for uniformizing the widthwise heating action of the stamp substrate 25 and the like at the time of preheating and main heating can be performed. This has the effect of being simple.
