The present invention relates to a plastic name plate formed with a hologram, and in detail, is attached to various electronic products such as communication devices, TVs, VCRs, game machines, refrigerators, air conditioners, household goods such as cosmetics and jewelry boxes made of plastic, and aquariums. Of nameplates to promote the company's image by forming holograms to display the brand of the manufacturer in various industrial products such as displays, display racks, fancy items such as photo frames, nameplates, and various advertising items such as plaques / labels It is about a method.

The hologram is a three-dimensional image recorded on a surface similar to a photographic film by using the interference effect of the light generated by the two laser lights to meet each other, and visually has various three-dimensional effects.

That is, the hologram has a visual effect such as a three-dimensional shape according to the angle of refraction of light, and the advertisement effect is prominent due to the luxurious image.

Accordingly, brands such as logos and emblems to represent a company are manufactured on nameplates or various panels in the form of holograms, attached to products, and widely promoted through mass media.

On the other hand, the name plate represents the image of the product and its manufacturing company, so that the more attached to the expensive or precise products should be made more beautiful, and in general, the smaller the product should be made of thin so as not to look clunky.

Recently, the importance of nameplates that are used in a variety of applications, such as LCD screens of mobile phones and display parts of electronic products, has also been highlighted.

Such nameplates are manufactured by various materials (plastics, glass, ceramics, metals, non-metals, etc.) and manufacturing methods. For example, there are vacuum deposition methods, plastic injection molding, press processing, die casting, engraving, and the like. .

Referring to Figure 1, the manufacturing method of the name plate formed with a hologram according to the prior art is a step (deposition step) of depositing chromium on the back of the disc using a vacuum deposition method on the back of the disc, such as a transparent acrylic plate, After the chromium is deposited on the back surface of the original plate by the deposition step to form a deposition layer, a step of forming a printed layer by silk printing on one surface of the original plate (printing step), and a window portion for displaying at a predetermined position of the original plate And peeling off the deposition layer of the portion where the holographic character is to be formed (removal step), and removing the deposition layer by the removal step, and then washing the original plate on which the deposition layer and the print layer are formed using a fabric cleaner (water) ( Washing step), drying in a conveyor type dryer (drying step), processing into a nameplate of a type suitable for each electronic product (processing step), and Forming a holographic letter using a hot stamping method on a portion where the holographic letter of the name plate formed through the step is to be formed (hot stamping step), and after forming the hologram by the hot stamping method, an adhesive layer is formed on the surface thereof It consists of a step (adhesive step).

However, when the name plate manufactured by the method described above is closely observed in the holographic character part, embossing, that is, a concave convex shape appears on the holographic character part, and a bubble or scratch defect occurs.

The defects such as embossing, scratches, bubbles and the like are mainly generated in the process of attaching the hologram foil to the character part through the hot stamping step. According to the related art, there is no separate step for correcting the above defects.

Embossing, scratches, bubbles, etc. of the holographic letter portion of the defects of the holographic character portion of the reflectivity is lowered, thereby lowering the publicity effect through the name plate on which the hologram is formed.

In addition, in the manufacturing process of the nameplate, such defects are severe and the products treated as defective products appear in a significant proportion, resulting in lower productivity and higher production costs.

Accordingly, the present invention has been made to solve the above problems, an object of the present invention is to provide a method for producing a name plate for removing defects such as embossing, scratches, bubbles in the name plate on which the hologram is formed.

In addition, an object of the present invention is to remove the defects of the holographic character to make the interference pattern inherent in the holographic character remarkably appear to exert even more excellent advertising effect.

In addition, the present invention has an object to contribute to cost reduction and productivity improvement of the company by reducing the defective rate in the process of manufacturing the name plate formed with the hologram.

Characterized in that it is included.

2 is a view showing one example of a name plate produced by the present invention.

The name plate 20 as shown in FIG. 2 is mainly applied to a display of a mobile communication device, and includes a window portion 22 serving as a display portion and a character portion 24 on which holographic characters are formed.

However, the present invention is not limited to the form as shown in FIG. 2, and the form of the name plate may be variously manufactured.

Hereinafter, various exemplary embodiments will be described with reference to the accompanying drawings.

<First Embodiment>

3 (a) and 3 (b) are process diagrams illustrating a method of manufacturing a name plate on which a hologram according to a first embodiment of the present invention is formed.

Referring to Figure 3 (a), the manufacturing method of the name plate formed with the hologram according to the first embodiment is a hot stamping step of forming a holographic letter on the plastic disc, and the step of heat-treating the hot stamped plastic disc Characterized in that it comprises a.

In addition, as shown in (b) of FIG. 3, in addition to the process of FIG. 3 (a), forming a printing layer using a mirror ink prior to the hot stamping step, the hot stamping step, and the heat treatment. A step of forming a heat treatment protective layer for protecting the holographic foil formed by the hot stamping step may be further included between the steps.

Hereinafter, a state diagram showing a manufacturing method of a name plate having a hologram according to a first embodiment of the present invention will be described with reference to FIG. 4.

First, a disc 40 having a predetermined thickness is prepared.

Here, the disc 40 has a thickness of 0.4mm ~ 10mm, plastic materials such as acrylic resin (PMMA Resin), PC (polycarbonate), PET (Polyethylene-Terephthalate), PE, ABS and the like are used.

Next, a hologram foil 43 having a holographic letter, such as a company logo, a brand, or the like, is formed on one side of the disc 40, preferably the back side, by using a hot stamping method (hot stamping step).

Here, in the case of attaching the hologram foil 43 to the back of the disc 40, the back of the hologram foil 43 is pressed and hot stamped, and the hologram foil 43 is placed on the front surface (surface) of the disc 40. In the case of attachment, the front surface of the hologram foil 43, that is, the portion displayed on the letter portion is pressed and hot stamped.

The hot stamping method generally means thermal transfer printing, and indirectly heats, presses and transfers a hologram foil having a predetermined size or a predetermined brand or company logo engraved thereon without being directly printed. Say

Specifically, a hologram foil 43 having a predetermined size made of a synthetic resin film is positioned where a holographic character is desired to be engraved, and about 2 to 5 at a temperature of about 150 ° C. to 200 ° C. and a pressure of 5 kg / cm 2. Squeeze for seconds.

At this time, a predetermined brand or company logo engraved on the hologram foil 43 is engraved on the disc 40.

After the hologram foil 43 is formed on the disc 40 as described above, as shown in FIG. 4 (b), the heat treatment protective layer 46 is applied to the outside (back side) of the hologram foil 43 by silk printing. (Heat treatment protective layer forming step) When the holographic foil is attached to the front surface (surface) of the original plate, a heat treatment protective layer is formed on the attached holographic foil through transparent ink printing.

The reason for forming the heat treatment protective layer 46 by silk printing on the hologram foil 43 is that damage to the hologram foil 43 by blocking the hologram foil 43 from being directly exposed to heat in the heat treatment step of the following process. This is to prevent.

However, it is also possible to perform the heat treatment step, which is the next process, without going through the heat treatment protective layer forming step through the silk printing.

The heat treatment protective layer 46 through the silk printing may be formed only on a part of the hologram foil 43 as shown in (c) of FIG. 4, or may be formed on the entire disc 40 except for the window part 22. It is possible.

At this time, when the heat treatment protective layer 46 is formed on the entire disc 40, the effect of embossing and removing bubbles of the hologram by the heat treatment step of the following process is inferior to that of the partial process.

The reason for this is that the hologram foil 43 is also expanded and contracted by the expansion and contraction of the plastic disc 40 in the heat treatment step of the following process, and defects such as embossing, bubbles, and scratches are eliminated. This is because, when the entirety of 43 (43) is wrapped with the heat treatment protective layer 46, there is no space for the hologram foil 43 to expand and contract.

Therefore, preferably, as shown in (c) of FIG. 4, it is preferable to silk-print only a portion of the hologram foil 43 to form the heat treatment protective layer 46, which results in a better heat treatment effect.

In addition, when the heat treatment protective layer forming step is performed, the window name plate on which the heat treatment protective layer 46 is formed is dried at a temperature of 40 ° C. or higher for 10 minutes or more, preferably at 45 ° C. for 15 minutes. At this time, if the disc used is a PC material, when the drying at a temperature of 60 ℃ or more whitening phenomenon that the disc may turn white should be noted.

In addition, the disc of PET material does not cause heat whitening, but the disc of A-PET material may cause heat whitening, so care should be taken when drying.

The name plate formed as shown in FIG. 4 is heat-treated, specifically, the portion of the hologram foil 43 of the disc 40. (Heat treatment step)

The heat treatment may be performed by various methods such as placing a nameplate in an oven and applying heat or by placing the nameplate directly near a burner flame to apply heat.

The heat treatment step may be any method that allows the disc of plastic material to soften and expand, and is not limited to the above-mentioned method.

At this time, the heat treatment temperature is 70 ℃-300 ℃, the heat treatment time is 5 minutes or more, preferably the heat treatment temperature is 85 ℃, heat treatment time is about 60 minutes.

When the plastic disc 40 is softened and expanded by the heat treatment step, the hologram foil 43 coupled to the disc 40 is also expanded. Although there is a difference depending on the material of the plastic disc 40 used, in the case of acrylic resin it starts to soften at about 8 ℃.

At this time, as the hologram foil 43 expands, concave embossing and bubbles disappear, and if the name plate is gradually cooled after heat treatment, the expanded plastic disc 40 shrinks and defects such as scratches disappear.

After correcting the defects due to the heat treatment step as described above, in order to prevent the scratching of the printed layer printed on the disc 40, as shown in Fig. 4 (d), silk printing to form a scratch protective layer 49 Overprinting process can be added using (overprinting step).

The overprinting step is to prevent scratches by forming an additional scratch protection layer 49 on the back surface of the disc on which the hologram foil 43 and the heat treatment protection layer 46 are selectively formed.

As shown in FIG. 4D, when the overprinting step is added, a hologram foil 43 is formed on the disc 40, and a heat treatment protective layer 46 is formed on the hologram foil 43. Thereafter, the scratch protective layer 49 is formed through an additional overprinting step.

On the other hand, when the holographic foil is attached to the front surface (surface) of the original plate 40, the heat treatment protective layer and the scratch protective layer are simultaneously formed on the holographic foil by transparent ink printing, except for the portion where the holographic character is to be formed thereon. Alternatively, the holographic character portion is formed by attaching an injection-engraved holographic character.

However, in FIG. 4D, when the step of forming the heat treatment protection layer 46 is omitted, the scratch protection layer 49 may be formed directly on the hologram foil 43.

The overprinting step may also be omitted since it is not a necessary process. When the overprinting step is performed, the overprinted scratch protection layer 49 is dried at 80 ° C. for at least 30 minutes after the overprinting step.

On the other hand, as shown in (e) of FIG. 4, before the hot stamping step, the step of forming the printing layer 42 using mirror ink on one surface of the disc 40, preferably on the rear surface, is performed. Can be added (print layer forming step)

In FIG. 4E, the print layer 42 is formed on the master plate 40 using mirror ink, the hologram foil 43 is formed by using a hot stamping method, and the heat treatment protection is performed on the hologram foil 43. After forming the layer 46, the original plate except the window part 22 is overprinted, and sectional drawing of the original plate which formed the scratch protection layer 49 is shown.

As described above, in FIG. 4E, the heat treatment protective layer 46 or the scratch protective layer 49 may be omitted.

In the printing layer forming step, MIR 8100 or MIR 9100 mirror silver ink products suitable for PC, PET and the like were used.

The mirror ink has good concealability and is not affected by black overprinting of hue or gloss, and can be printed only on a desired surface to replace deposition and etching processes.

In addition, since it has a gloss similar to gold foil or silver foil, and exhibits a high quality mirror effect, it is possible to replace the step of forming a conventional deposition film.

That is, in general, in order for the name plate to reflect light, such as the gloss of metal, the nameplate had to go through the process of depositing a metal such as chromium and etching the letter part. May be omitted.

In the process of printing the mirror ink, only the character portion 24 in which the hologram character is formed is printed, or the entire necessary portion except the window portion 22 is printed, and after printing, it is dried at 40 ° C. or more for 10 minutes or more. .

In the case where the mirror ink is printed only on the character portion, after the drying, the mirror ink of the same color is printed on all of the necessary portions except for the window portion 22, and after printing, the mirror ink is dried at 40 占 폚 or more for 10 minutes or more.

In addition, the dried ink print coating film is preferably 3 microns or less in order to prevent peeling of the mirror ink layer. After that, it can be overprinted for the purpose of preventing scratches.

Subsequently, the final name plate is completed to complete the name plate on which the hologram according to the present invention is formed.
