Description

Akira Ishida's seal surface

The present invention relates to a stamping surface of a penetrating stamp made of a thermoplastic resin having open cells, and more particularly to a stamping surface of a penetrating stamp that can form a dense imprint image. Background art

The penetrating marking device applies light or heat to a stamp surface made of thermoplastic resin with open cells while strongly pressing the negative film, and melts and cures the part where the light or heat has penetrated. It is known that you can stamp. The imprint by the stamp surface is formed by extruding the ink that has penetrated the resin having open cells in the portion that has not been melt-cured by the stamping.

Therefore, in an image in which the light and dark areas of the imprint are clear, such as characters, it is expected that a clearer imprint will be formed by sufficiently exuding the ink from the pores forming the imprint surface.

However, in the case where light and dark areas are mixed like an image, or when an image is expressed by the difference in light and dark tones, if there is too much ink supplied from the stamp surface for a certain pixel, the adjacent pixels Until the ink bleeds, the imprint becomes unclear.

In particular, when a stamp is formed based on a digital image such as a digital camera image, even if a stamp with a high resolution can be formed based on high-resolution data, an imprint is imprinted when the stamp is actually stamped. There was a situation that could only be realized. Disclosure of the invention

The present invention has been made in view of such problems of the conventional technology, and controls the amount of ink supplied to a medium such as paper from each bubble on the surface of a stamp surface made of a thermoplastic resin having continuous bubbles. To provide a penetrating stamping surface that can achieve high-resolution imprinting The purpose is to:

Hereinafter, embodiments of the present invention will be described.

Seal face of penetration seal

The thermoplastic continuous porous material used in the present invention is not particularly limited, but it is desirable to use a polyurethane-based resin, a polyethylene-based material such as polyethylene, polypropylene, or polystyrene, a polypropylene-based material, or a styrene-based elastomer. As these thermoplastic resins, those having a melting point of 190 ° C. to 210 ° C. are preferably employed.

In order to convert the thermoplastic resin into open cells, there is no particular limitation, but a method of treating the polyolefin resin with calcium sulfite or an inorganic acid that dissolves calcium sulfate (for example, Japanese Patent Publication No. 47-39212) And non-ionic surfactants or polyhydric alcohols, and a kneaded powdery thermoplastic polyolefin resin that is insoluble in organic solvents and soluble in water or acidic aqueous solution. A method of washing the object with water (for example, see Japanese Patent Publication No. 57-42561). Also, It is also possible to use a method of breaking open the cells having a closed cell with a needle punch or the like to obtain open cells.

The thermoplastic resin having open cells obtained in this way is molded and / or sliced to a thickness of 0.4 mm to 1.2 thighs, and becomes a material for a stamp face. This stamp face preferably has a bubble rate of 65 to 85%. Further, the average cell diameter of the bubbles is 2 Ojm to 50〃m, and / or the gas force-C hardness is 30 ° to 70 °. , A clear imprint can be realized.

The stamped surface of the penetrating stamp is formed by applying light or heat while strongly pressing a negative film against a stamped surface made of a thermoplastic resin having open cells, and melting and hardening a portion through which the light or heat has passed. Specifically, a mask film is directly covered on the foam, and heat rays (or light rays) are selectively irradiated to absorb the heat rays (or light rays). The bubbles form a part without being absorbed. Then, when ink is penetrated into the stamp surface and imprinted, the ink contained in the air bubbles (portion where the air bubbles are not crushed by heat irradiation) oozes out. Since bleeding does not exude, a seal imprint is formed by these two portions (see Japanese Patent Application Laid-Open No. H6-1555698). The original image serving as the negative film may be a digital image captured by a digital camera or the like.

FIG. 1 and FIG. 2 show the penetrating stamp of the present invention and its stamp face. As shown in FIG. 1, the penetrating stamp 10 generally comprises a stamp 1 and a holder 2 supporting the stamp 1 _c. The stamp 1 of the present invention is mounted on the tip of the holder 2 of the stamp 10. It is then used as a stamp 10. The stamped surface 1 is made of a thin layer of resin having open cells. The stamped surface layer 11 is printed by melting the resin with a stamped heat ray (or light beam), and the ink supply layer is used to hold and supply ink. 1 and 2.

Ink supply is required to form a seal. Generally, ink is supplied from an ink tank provided in the holder (back supply) or from an ink holder that comes into contact with the surface of the stamp. (Surface supply). In the present embodiment, unlike these, a sufficient amount of ink is applied to the surface of the stamp surface in advance and left for a few minutes, and the ink is passed through the stamp surface layer 11 of the stamp surface to form an ink holding layer 12 (open air bubbles). Ink inside the thin resin layer) and then wiping off excess ink. The means of supplying ink from the supply layer 12 was adopted. By performing this ink supply once, stamping can be performed 100 times in the stamp of the present embodiment. In addition, since the ink is held on the stamp surface, it is preferable that the ink be stored with a cap (cap 3 shown in FIG. 2) after use.

FIG. 2 is an X-X sectional exploded view of the stamp 10 shown in FIG. A cap 3 covers the stamp 1 to prevent the stamp from drying out. The stamped surface 1 made of a thermoplastic resin having thin open cells has a stamped surface layer 11 to be stamped, and holds the ink supplied from the surface of the stamped surface layer 11 again. And an ink holding layer 12 to be supplied. The thickness of the stamp face 1 is indicated by "t" in FIG. In this embodiment, the thickness of the stamp surface 1 is 0.4 thigh to 1.2 thigh. The thickness of the stamp face 1 is the sum of the thickness of the stamp face layer 11 and the thickness of the ink holding layer 12. Here, since the engraved surface layer 11 is an image formed by melting with light or heat, its thickness is extremely thin. However, in the present embodiment, the imprint surface 1 is provided on the upper surface of the elastic layer 4 so that the force received at the time of imprinting is dispersed evenly over the entire imprint surface 1 to form a clear imprint.

Thus, thickness 0.4 M! The stamped surface of a penetrating stamp made of a polyurethane resin having a thin layer of up to 1.2 mm and having open cells with a cell ratio of 65 to 85% has a small average cell diameter and moderate hardness. For this reason, at the time of imprinting, since the ink contained in the open cells is supplied in a very small amount within a range corresponding to the fineness of the pixels of the printing plate, it is possible to clearly express a fine image of pixels. It is possible to realize a photo-like image while being a seal.

Seal

An original image is created based on an image taken by a digital camera, and the stamp face (FIG. 3 (a)) according to the present invention and the conventional stamp face (FIG. 3 (b)) created based on the original image are compared. Compared. FIG. 3 shows an imprint (a) using the stamp 1 of the penetrating stamp according to the present invention and an imprint (b) using the conventional stamp.

FIG. 3 (a) shows a seal imprint when the seal face 1 of the penetrating seal according to the present invention is used. This imprint is based on the original digital image of a person taken with a digital camera, but the face of the person appears as a photographic image. This means that stamp face 1 has a thickness of 0.4 The ink contained in open cells with a bubble ratio of 65 to 85% is supplied in a small amount within a range corresponding to the fineness of the pixels of the printing plate. This is because images with fine pixels can be clearly expressed.

On the other hand, Fig. 3 (b) shows the imprint formed by the stamp surface supplied with ink from the ink holder (surface supply) in surface contact with the surface of the stamp surface. Unlike the imprint shown in Fig. (A), a large amount of ink is supplied, which blurs and blurs the outline of the character. In this case, the character can be read clearly, but fine pixels such as portraits have small pixels. Images cannot be clearly expressed.

As described above, the difference in the imprint is that the imprint surface according to the present invention is a thin layer having a thickness of 4 mm to 1.2 thighs, and the material thereof is an open cell having an air bubble rate of 65 to 85%. This is due to the use of polyurethane resin. The stamp surface manufacturing apparatus according to the present invention will be described with reference to FIGS.

FIG. 4 is a block diagram of the stamp production apparatus 100. The stamp manufacturing apparatus 100 of the present invention includes a transmitting / receiving means 20 capable of transmitting and receiving to and from a user terminal 60, and a stamp original editing means for editing a stamp original based on the stamp configuration information received from the user terminal 60. 30 and an output unit 40 for sending the stamp surface document information edited by the stamp surface document editing unit 30 to a stamp surface forming unit 50 for forming a stamp surface.

Further, the stamp editing means 30 sends the stamp document information to the user terminal 60, acquires the user's confirmation information for the stamp document information, and outputs the stamp document information in response to the confirmation information. And a billing unit 33 that performs a billing process in accordance with the acquisition of the confirmation information.

The control in the document editing means of the stamp manufacturing apparatus 100 will be described based on the flowchart of FIG.

First, the stamp surface configuration information input from the user's terminal is acquired via the transmission / reception unit 20 (step 1). This stamp surface configuration information is information necessary for configuring the stamp surface. For example, image information that constitutes a stamp surface, information about the size of an image, information about the layout of an image, information about the image freshness (analysis degree), and the like. These can be answered alternatively on the preset items on the specified answer form screen. The stamp configuration information may be transmitted from the user terminal to the stamp manufacturing apparatus 100 by e-mail, or may be expressed in free words by e-mail or the like. The information may be transmitted to the stamp manufacturing apparatus 100 via a home page on the Internet. Next, the manuscript editing unit 31 in the stamp manuscript editing means 30 creates a stamp manuscript (print manuscript information) based on the above-described stamp structure information (step 2). The stamp may be created as it is, but in order to obtain the final confirmation of the user, the stamp manuscript information is once sent to the user terminal 60 (step 3). The user who has received the stamped document information compares the stamped document information with the desired stamped surface configuration to determine whether the stamped document is appropriate (step 4).

Here, if the user decides that “the stamped manuscript is inappropriate (step 4), it sends confirmation information to that effect to the stamped surface manufacturing apparatus 100, and receives the information. The original confirmation section 32 of the printer causes the stamp original editing section 31 to edit the stamp original again (step 2).

On the other hand, if the user determines that the stamp original is appropriate (step 4), the user transmits confirmation information to that effect to the stamp manufacturing apparatus 100, and receives the information. The original document checking unit 32 of 00 determines to manufacture a stamped surface based on the stamped original (step 5).

Based on this determination, charging section 33 performs charging processing, and transmits charging information to user terminal 60. Before or after this billing process, the document checking section 32 sends the stamp face document information confirmed by the user to the output means 40 (step 8), and further outputs the stamp face forming means 5 from the output means 40. Send to 0 (Step 9).

The stamp forming means 50 that has obtained the stamp document information applies light or heat while strongly pressing the negative film against the surface of the thermoplastic resin having open cells, and melts and cures the portion where the light or heat has passed. To form a stamped surface. This stamp may be the stamp of the penetrating stamp according to the present invention or a stamp obtained by a known means. The penetrating stamp thus manufactured is arranged for delivery to the user. (Step 10).

According to the present invention, a stamp original can be edited based on a configuration desired by the user, and a billing process is performed after confirming the edited original by an original checking unit. be able to. This makes it possible to create a stamp face that meets the user's desires (image, structure, layout, freshness, etc.). In addition, billing processing can be performed after forming the stamped surface, and after the stamped surface is created or billed, there is no trouble such as not meeting the user's wishes, and production is smooth. , Delivery, billing can be done.
