JP5713382B2 - Metallic card - Google Patents

Description

The present invention is primarily directed to high metallic card-designed for the high-definition picture and other information shiny printable display.

  In cards such as a credit card and a cash card, the design of the card is improved by printing a pattern or the like on the surface of the card (for example, see Patent Document 1). There is also an example in which glossy printing is adopted as printing on the card surface.

  FIG. 4 is a cross-sectional view of a conventional metallic card that employs glossy printing as printing on the card surface. The metallic card MC shown in the figure has an IC chip layer 12 having a structure in which an IC chip 12A is sandwiched between two upper and lower white film base layers 12B and 12B, and gold, silver, a hologram, etc. on the surface of the IC chip layer 12 The gloss printed pattern layer 13 has a gloss printed pattern layer 13 formed by printing a pattern by gloss printing and a non-gloss printed layer 14 printed by information on the back surface of the IC chip layer 12 by non-gloss printing. The design itself is enhanced by the glossy reflection of light. Note that the surfaces of the glossy printed pattern layer 13 and the non-glossy printed layer 14 are each protected by a transparent protective film layer 11.

  By the way, in the conventional metallic card MC, the glossy printed picture layer 13 is formed by screen printing. This is because when performing glossy printing of gold, silver, hologram, etc., the glossy printed pattern layer 13 must be formed as a thick ink layer of several tens of microns or more in order to obtain the texture.

  For this reason, screen printing cannot print high-definition patterns and other information. Therefore, the conventional metallic card MC has a high-design metallic card that can print and display glossy high-definition patterns and other information. There is a problem that it cannot be obtained.

  Furthermore, in the conventional metallic card MC, since the pattern of the glossy printed pattern layer 13 is provided by printing between the film base layer 12B and the protective film layer 11 (intermediate printing by screen printing). , It becomes multi-faceted printing and is not suitable for small lot production (production of metallic cards of 5,000 sheets or less). In addition, when making a metallic card MC with a different pattern, it is necessary to change the pattern for intermediate printing to change the metallic card MC from the beginning, and the delivery time is long to obtain the metallic card MC as the final product. There is also the problem that it takes.

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the accompanying drawings.

<Outline of metallic card configuration>
FIG. 1 is a sectional view of a metallic card to which the present invention is applied. The metallic card MC shown in FIG. 1 includes a base card 1 that emits gloss by including a gloss layer 10, and a light-transmitting print layer (hereinafter referred to as “front print layer”) that includes a pattern and other information printed on the surface of the base card 1. 2 ”) and a printed layer printed on the back surface of the base card 1 (hereinafter referred to as“ back printed layer 3 ”).

<< Detailed Configuration of Base Card 1 >>
The base card 1 has a configuration in which a transparent protective film layer 11 is provided on the upper and lower surfaces of the gloss layer 10 and an IC chip layer 12 is provided between the lower protective film layer 11 and the gloss layer 10. .

  In the metallic card MC of FIG. 1, the surface printed layer 2 is formed with a non-glossy ink so that the color of the pattern and other information displayed by the surface printed layer 2 is made a non-glossy color. In order to use the glossy layer 10 as the background of the information, the glossy layer 10 is a method of filling the entire background area of the IC chip layer 12 or the entire background area with glossy ink (ink containing glossy particles) (solid). (Painting method).

  As the glossy layer 10 as described above, for example, a layer that emits a metallic luster by including metal particles such as aluminum or metal particles processed from the same as the glossy particles (hereinafter referred to as “metallic glossy layer”), or hologram gloss Can be employed (hereinafter referred to as “hologram gloss layer”).

  The IC chip layer 12 has a structure in which the IC chip 12A is sandwiched between two upper and lower white film base layers 12B and 12B, but is not limited to this structure.

<< Detailed Configuration of Front Print Layer 2 and Back Print Layer 3 >>
The surface printing layer 2 is formed by offset printing (external printing) and thus has a small thickness and light transmittance. Since the above-described gloss layer 10 exists on the lower surface side of the surface print layer 2, the gloss of the gloss layer 10 appears to shine through the surface print layer 2 when the surface print layer 2 by this offset printing is viewed from the upper surface. .

  The front print layer 2 can be formed by a printing method other than offset printing. In this case, the front print layer 2 is provided with light transmittance equivalent to that of offset printing.

  The back printing layer 3 is also formed by offset printing (external printing), but the back printing layer 3 may be formed by a printing method other than offset printing.

  In the example of FIG. 1, a configuration is adopted in which the surface print layer 2 is protected by providing a transparent overprint layer 4 on the surface print layer 2. It can also be provided on the back printing layer 3. Further, if it is not necessary to protect the front print layer 2 and the back print layer 3, the overprint layer 4 may be omitted.

《K value of metallic card MC》
FIG. 2 is a visual print evaluation result when the metallic feeling and the color change of the front printed layer 2 of the metallic card MC in FIG. 1 are visually observed and evaluated. In this evaluation, a K (black) value (hereinafter referred to as a “K value of a metallic card”) obtained by measuring one surface of the base card 1 with a reflection densitometer in a state in which the front printed layer 2 is provided on one surface of the base card 1. ), How the metallic feeling and the color change change between the light-colored surface printed layer 2 and the dark-colored surface printed layer 2 were evaluated. The reflection density is represented by log ₁₀ 1 / R, R × 100 = reflectance.

<Lower limit of K value>
Referring to FIG. 2, when the K value = 0.3 to 0.4, both the light-colored surface print layer 2 and the dark-colored surface print layer 2 have a metallic feeling (metallic feeling ○) and no color change (color change). ○). Further, when the K value is from 0.25 to 0.2, the light color print layer 2 and the dark color print layer 2 are slightly lacking in metallic feeling (metallic feeling Δ), but there is no color change (color change ○). . However, when the K value = 0.15, neither the light-colored front print layer 2 nor the dark-colored front print layer 2 lacks the metallic feeling (metallic feeling x). For this reason, the lower limit of the K value of the metallic card is preferably 0.2.

<< Upper limit of K value >>
Referring to FIG. 2, when the K value = 0.55, although a slight color change occurs in the light color print layer 2 and the dark color print layer 2 (color change Δ), there is a metallic feeling (metallic feeling). ○). However, if the K value = 0.6, a large color change occurs in the light-colored front print layer 2 (color change ×), and for example, a person's face is drawn on the front print layer 2. , Troubles such as faint color of the face occur. For this reason, the upper limit of the K value of the metallic card is preferably 0.55.

<< Summary of K value >>
As described above, the K value when one surface of the base card 1 is measured with the reflection densitometer in the state where the front printed layer 2 is provided on one surface of the base card 1 is included in the range of 0.2 to 0.55. Preferably. Within this range, the pattern and other information drawn by the front print layer 2 have little color change and an appropriate metallic feeling can be obtained.

<< Grain size of glossy particles contained in glossy layer 10 >>
FIG. 3 shows the results of visual printing evaluation when visually observing and evaluating the particle feeling, glitter feeling, and rough feeling of the surface printing layer 2 when a metallic gloss layer is employed as the gloss layer 10 of the metallic card MC of FIG. It is. In this evaluation, depending on the particle size of the glossy particles (hereinafter referred to as “glossy particle size”) contained in the metallic gloss layer (gloss layer 10), the grain feeling, glitter feeling, and graininess of the surface printing layer 2 are We evaluated how it changed.

<Lower gloss particle size>
Referring to FIG. 3, when the glossy particle size is 30 to 35 μm, it is possible to obtain a good particle feeling, glitter feeling, and rough feeling as a printed matter (particle feeling ○, glitter feeling ○, and rough feeling ○). When the glossy particle diameter is 25 μm, although the particle feeling is somewhat lacking (particle feeling Δ), the glittering feeling and the rough feeling are good (shining feeling ○, rough feeling ○). However, when the glossy particle diameter is too small, such as 20 μm, the particle feeling is almost lost (particle feeling ×). For these reasons, the lower limit of the glossy particle size is preferably 25 μm.

<Upper limit of glossy particle size>
Referring to FIG. 3, when the glossy particle size is 40 μm, the rough feeling is slightly increased (grainy feeling Δ), but there is no practical problem as a printed matter. However, when the glossy particle diameter is 45 μm, the rough feeling becomes too large (the rough feeling ×), which causes a practical problem as a printed matter. For these reasons, the upper limit of the glossy particle diameter is preferably 40 μm.

<Summary of Glossy Particle Size>
As mentioned above, it is preferable that a gloss particle diameter is the range of 25-45 micrometers. If it is this range, moderate particle | grain feeling, a glittering feeling, and a rough feeling will be acquired in the pattern drawn by the surface printing layer 2, and other information.

  In the metallic card MC of the present embodiment described above, as a specific configuration, a light-transmitting front print layer 2 made of a pattern or other information is formed on the surface of the base card 1 that emits gloss by including the gloss layer 10. The structure which provides is adopted. Therefore, for example, the glossy layer 10 is formed thick by offset printing to give the glossy layer 10 a glossy texture (glossiness), and the surface printing layer 2 is formed by screen printing to form a light transmissive layer. A certain high-definition surface print layer 2 can be provided, and in this case, the surface print layer 2 appears to shine through the gloss of the gloss layer 10, so that a high-definition picture with glossiness and other information is printed and displayed. can do.

<< Other Embodiments of Metallic Card >>
The metallic card MC in FIG. 1 is an example in which the front printed layer 2 of the base card 1 produces a glossy feeling, but the back printed layer 3 of the base card 1 is made light transmissive by screen printing similar to the front printed layer 2. By giving and making the film base material layer 12B of the IC chip layer 12 transparent, the back printed layer 3 can also be configured to have the same glossiness.

  In the metallic card MC of FIG. 1, the IC chip layer 12 of the base card 1 can be omitted. In this case as well, the back printed layer 3 may be configured to have a glossy feeling by imparting light transmittance.
