Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

In the present invention, it is extremely difficult to confirm an image in a state before the image appears.
The present invention relates to a printed material that can make an image appear by rubbing a printing surface with a coin, a coin, a medal, or the like, or by applying pressure from above.

[0002]

2. Description of the Related Art Conventionally, as a printed matter capable of making an image appear by rubbing the surface with a coin, for example, as proposed in Japanese Patent Publication No. 6-78039,
By printing an image such as a pattern or a number on the printing substrate with an ink composition containing a material having a higher hardness than the coin metal, and rubbing the printed portion of the image from above, the coin metal shaved off 2. Description of the Related Art A printed material in which a printed portion is colored and an image appears is known.

[0003] Further, as a printed material in which an image is concealed, a printing layer is applied on the image to be concealed by solid printing, screen solid printing, overprint varnish printing, or silver ink is applied on the image by silk screen printing. In some cases, the concealing layer is printed to make the image invisible, and the concealing layer using the silver ink is scraped off so that the image can be viewed.

[0004]

By the way, in the printed matter as described above, a difference in gloss is produced between a printed substrate and a printed surface on which an image is printed with the ink composition, and the printed surface is changed to a coin by changing the viewing angle. There is a problem that an image printed on the printing base material can be confirmed before the substrate is rubbed, or the image can be seen through when the printing base material is exposed to light.

[0005] The latter printed matter has an effect of concealing an image, but has a problem that the concealing layer is in a single color solid coating state, and only a simple one can be manufactured.

Accordingly, an object of the present invention is not to cover an image with a printed layer superimposed thereon, but to effectively utilize the characteristics of human visual recognition, and to capture the image with the eyes before the image appears. However, it is difficult to confirm the image due to the optical illusion using the visual characteristics of the eyes.Moreover, even if the printing substrate is exposed to light, the image does not show through, and the colors and patterns are not It is an object of the present invention to provide a printed matter that can obtain a complicated and varied printed matter, and can produce a clear image by rubbing a printed surface with a coin or applying pressure from above.

[0007]

Means for Solving the Problems In order to solve the above problems, the invention of claim 1 provides an illusion using an ink composition on a printing substrate and an image using visual characteristics. In order to generate the above, a configuration in which a printing layer having contrast is printed on a printing base material is employed.

According to a second aspect of the present invention, an image is formed with an ink composition on a printing base material, and an illusion using visual characteristics is generated for the image. Is printed.

A third aspect of the present invention is the ink composition according to the first or second aspect, wherein the image contains a material having a higher hardness than metals such as coins, coins, and medals used to display the image. The printed configuration is adopted.

[0010] A fourth aspect of the present invention is the invention according to the first to third aspects, wherein the printing layer is a multicolor print.

A fifth aspect of the present invention is the invention according to any one of the first to fourth aspects, wherein the printing layer has a configuration in which the printed layer is a pattern or a geometric pattern.

[0012]

Embodiments of the present invention will be described below with reference to the drawings.

First, the characteristics of human visual recognition are listed. (1) Human vision has the characteristic of strongly recognizing contrast. (2) It is known that when two large and small stimuli are given in close proximity in time and space, a large stimulus is recognized, and a small stimulus is not recognized. As a result, a masking phenomenon in which one is invisible is known. ing. (3) Divided figures have a visual characteristic that it is difficult to identify them. (4) In general, when a visual attention is strongly directed to a certain stimulus, a visual characteristic of “effect of attention” in which perception to another stimulus is weakened is also known.

The printed matter of the present invention makes use of the above-described characteristic of human visual recognition effectively and effectively, and it is difficult to confirm the image even before the image appears, , So that the image does not show through even when the printing substrate is exposed to light, and a clear image can be made to appear by rubbing the printing surface with a coin or applying pressure from above. It is.

As shown in FIGS. 1 and 2, a printed material 1 of the present invention uses an ink composition containing a material such as coins, coins, and medals having a higher hardness than a metal on a printing substrate 2 such as paper. In order to generate an illusion using visual characteristics with respect to the image 3, the printed substrate 2 or the printed layer 4 having a contrast with the image 3 is formed by printing.

In the case shown, the print layer 4 for the image 3 is:
An example is shown in which the image 3 is printed so as to partially cover it.

As described above, the image 3 on the printing substrate 2
A printing layer 4 having a contrast to the printing substrate 2 or the image 3 for generating an illusion using visual characteristics on the image 3 is applied to the entire surface of the printing substrate 2 or the image 3.
By partially overprinting or printing so as not to overlap at all only in the area of, the masking effect (visual masking) and the effect of attention are obtained because the printing layer 4 with contrast is recognized very strongly. This may cause the image 3 to be unrecognized, making it difficult to recognize what image 3 is being printed not only from the front but also from different angles. In addition, the presence of the print layer 4 on the image 3 prevents the image 3 from being seen through even when the printed matter 1 is exposed to light.

Incidentally, if the image 3 is printed on the white printing substrate 2 with the white ink composition and the printing layer 4 is printed with the green ink, the green printing layer 4 gives a strong stimulus. In addition, visual characteristics such as a masking effect and a caution effect in which the eyes cannot recognize the image 3 even when the image 3 is captured are effectively generated.

As the ink composition for printing the image 3 on the printing substrate 2, a material having a hardness higher than that of coins such as titanium oxide, aluminum oxide, silicon dioxide, and chromium oxide, for example, 10 to 80 is used. %, Letters, figures, patterns, etc. by well-known printing means, for example, offset printing, gravure printing, screen printing, letterpress printing, etc.
An image 3 such as a barcode is printed in an arbitrary color.

The color of the paper used for the printing base material 2 may be other than white, and the paper quality and thickness can be freely selected according to the purpose and application. The combination of the color of the ink composition for printing the image 3 on the printing substrate 2 and the color of the printing substrate 2 is also optional.

FIGS. 3A and 3B and FIGS. 4A to 4C show some of the printing layers 4 with contrast printed on the printing substrate 2. 9 illustrates a pattern. Although a geometric pattern is shown in the drawing, the print layer 4 can freely adopt a non-geometric pattern, marks and trademarks of various designs, designs such as pictures, numbers, and characters.

The ink used for forming the print layer 4 may be the ink used for general printing. The printing method is a known printing means such as offset printing, gravure printing, screen printing, letterpress printing. By using printing or the like, the print layer 4 may be represented by multicolor printing using a plurality of colors as well as colors and their densities, monochromatic or monochromatic shading.

For example, when the printing layer 4 having a single color and contrast is expressed, a clear contrast can be obtained by the color of the pattern or pattern by printing and the ground color of the paper. Not only the entire surface of 2, but also a mark or the like may be printed in one point.

Here, as described above, the human eye has a visual characteristic of strongly recognizing the contrast, and when seeing a pattern or pattern having a strong contrast with respect to the printing substrate 2, The pattern or pattern printed on the material 2 is strongly captured, and the image 3 having a weak contrast with respect to the printing substrate 2 is not recognized by the brain. As a result, the printed layer 4 of the printed pattern or pattern is printed. Is visually perceived, so that the image 3 existing on the printing base material 2 does not enter the eyes.

As described above, the image 3 on the printing substrate 2
In order to generate an optical illusion using visual characteristics for the image 3, when a print layer 4 having a design or pattern with contrast is printed on the print base material 2, human beings can strongly recognize the contrast of the print layer 4. By making effective use of the illusion effect caused by the visual characteristic of, and selectively capturing only the printed layer 4 of a pattern or pattern with contrast, recognition of the image 3 can be made difficult.

Further, since the image 3 and the printed layer 4 of a design or pattern having contrast exist partially or entirely so as to prevent the image 3 from being seen through even when the printed matter 1 is irradiated with light. be able to.

The printed matter 1 thus formed cannot normally recognize the image 3, and when the portion of the image 3 is rubbed with a coin from above the printed layer 4, the image 3 that has emerged in the printed layer 4 Can be used clearly as a substitute for a scratch card serving as a lottery lottery, and security can be maintained by printing on important documents and a part of a product. Further, it can be used for multipurpose such as forgery prevention and authenticity judgment by discriminating whether a document is a legitimate document or a product.

The printed material 1 used for the printing of the image 3 was an ink composition containing a material having a hardness higher than that of the coin metal. However, a printing material for the image 3 in which a magnetic material was mixed was used. For example, the image 3 can be read by magnetic means without being rubbed with a coin from above, and the printing substrate 2, the image 3 and the printing layer 4 can be colored by using a general ink for printing the image 3. By optically reading using the difference in wavelength, an invisible bar code or a two-dimensional code can be provided.

Further, a bar code or a two-dimensional code is printed on the image 3 using a special ink that generates magnetism, ultraviolet rays, far infrared rays, etc., and a printed layer 4 of a pattern or pattern with contrast is printed thereon. As a result, it is possible to provide a printed matter having a great deal of information which is invisible to the human eyes but can be read optically.

Further, a printing material 4 containing a developer is used for printing the image 3, and a printing layer 4 having a contrast is printed thereon to form a printed matter 1 concealing the image 3, and the printed matter 1 is overlaid on the printed matter 1. A color former is applied to the overlapping surface of another sheet, and pressure is applied from above the sheet superimposed on the printed matter 1 so that the color former of the sheet and the developer of the image 3, that is, carbonless carbon used for so-called slips, etc. It is possible to adopt a configuration in which the image 3 of the printed matter 1 is colored by a chemical reaction as seen in paper.

[0031]

As described above, according to the present invention, an image is formed on a printing substrate with the ink composition, and an illusion using visual characteristics is generated for the image. The printed layer with contrast is printed, so the characteristics of human visual perception are effectively used, and the printed layer with contrast is recognized very strongly, resulting in masking effect and attention effect on the image. It is difficult to confirm the image even if it is seen with the eyes before the image appears, and when viewing the printed matter from the front, naturally, even if the viewing angle is changed, It is possible to make it difficult to recognize whether or not the image is printed, and by making the pattern and pattern of the print layer overlap with each other, the image is not seen through even when the printed matter is exposed to light. .

In addition to rubbing an image printed on a printing substrate with a coin or the like to make it appear or develop a color, it also makes it difficult to see the image before rubbing with a coin or before reading on a printed matter that optically or magnetically reads the image. It is only necessary to apply a printing layer with a contrast to prevent forgery of documents and products with various types of lottery, toys, optically readable two-dimensional barcodes that do not have good visibility before rubbing. The printed material to be provided can be provided at low cost.
