The present invention relates to a color medal produced by a special inkjet type digital printing machine on a pattern (embossed) and an inscription (front surface) of a coin or a medal, and more specifically, the conventional methods 1 to 6 Unlike the color medal, which was produced only by the colors within the province, it is possible to express various colors and represent the natural color of individual photographs or artworks. The present invention relates to a color medal using digital printing to reproduce works of art and paintings, and a method of manufacturing the same.

To describe this in more detail, first, the medal is stamped in a special stamper by using a mold molded in the form of an intaglio pattern on a metal plate holder (published) of various forms such as a circle or a square for manufacturing a medal. In order to add visual effects and artistry to this stamped medal, a color medal is manufactured using a digital printing apparatus.

The conventional color medal manufacturing method applies the traditional Korean lacquer method and PAD printing method.

In the traditional lacquer method, after pre-treating the stamped medallion, a predetermined cloisonne glaze is added to the engraved cloisonne pattern and heated at high temperature. That's how. Cloisonne has a brilliant color and is not discolored, so the quality of the product is improved. However, since the whole process is performed by hand, mass production is difficult.

Recently, color coins or medals using a pad (PAD) printing method have been manufactured. This method refers to concave plate transfer printing, and unlike gravure printing and offset printing, it uses a tampon instead of a blanket when transferring ink.

Tampons can be printed on curved surfaces by using the flexibility of silicon material, so it is easy to print the position on the medal pattern easily and is continuously applied to color medals or coins.

However, this method can be used to print or gradate a single color by using various kinds of ink catching molds that deliver ink to the tampons for each color and part, but there are limitations in expressing mixed colors. Since the molds must be produced, it takes additional time and money to manufacture, which makes it difficult to reproduce the color tone of photographs or artworks of natural colors that are inexpensive and must be expressed in 'your own medal', which represents your unique personality. .

The present invention has been made to solve the above problems, and to provide a color medal and a manufacturing method for applying digital printing away from the conventional color medal manufacturing method.

The present invention is a digital printing device using a special color ink on a medal stamped in an embossed pattern, the implementation of a variety of colors to emphasize the visual effects and themes on the pattern or inscription of the medal, uniformity of quality and efficient mass The purpose of the present invention is to provide a color medal and a method of manufacturing the applied jig developed for the production.

The above and other objects of the present invention can express a work of art such as photographs or masterpieces in a variety of colors on the medal in a way that is different from the conventional method manufactured in a limited color of about 1 degree to 6 degrees. It is characterized by being achieved by the 'Own Medal', 'Masterpiece Series Medal', and so on.

The above and other objects and features of the present invention will be more clearly understood by the following detailed description.

The color medal according to the present invention has the following characteristics.

To manufacture color medals, various types of metal plates such as round or square are used and stamped patterns of molds are stamped into the computer to add predetermined colors and images to the stamps of embossed patterns stamped by special stampers. Computer graphic work is performed by scanning and entering the patterns of the medals and the prepared photographs or works. At this time, the corrective work so that the image added to the pattern or inscription of the medal is exactly the same. Here, when you want to put a picture or a work of art that represents your own unique personality, such as your own medals, you scan and edit the image.

  In the process of printing the edited image on the medal using a digital printing device, the stamped stamp is coated with a surface treatment agent so that printing ability and adhesion between the metal surface and the printing ink are good.

After the pretreatment process, the stamped medal is placed in the fixed jig (Jig) with the printing part facing upwards and printed using a special inkjet digital printing device. Inspect the position and color, and the medal passed the inspection is dried in the oven at 80 ℃ temperature for 15 to 25 minutes so that the printed portion is dried in nature, the manufacture of the color medal is completed.

That is, the present invention is a medal manufacturing process (10) for stamping in a special stamper with a mold formed in a pattern of the engraved form on a metal plate (published) of various forms such as round or square;

An image input process 20 for inputting an image using a digital camera or a scanner;

An image editing process 30 for editing the image input from the computer according to the color medal design;

A printing preparation step (40) of placing the stamping member on which the transparent metal pretreatment agent is applied to the medal fixing fixture so that the pattern to be printed is directed upward so that the stamp can be printed on the sheet;

A digital printing process 50 for printing a pre-edited image on a medallion using a special inkjet digital printing apparatus;

After the printing state is inspected, the medal is manufactured through a drying step 60 of drying at a temperature of 80 ° C. for 15 to 25 minutes in a drier.

Hereinafter will be described in detail through a preferred embodiment of the present invention.

EXAMPLE

A circular metal plate (published) having a diameter of 40 mm was stamped in a special stamper using a die engraved with a car (New Chairman) pattern.

At this time, the medal face of the embossed car (New Chairman) pattern was scanned and inputted into the computer, and then, according to the color medal design (pattern color: 1 New Chairman car, 2 inscriptions: 2 car backgrounds) Finish working on computer graphics.

In addition, the stamping plate to which the transparent metal pretreatment agent is applied is placed in the medal fixing fixture jig so that the pattern to be printed is directed upward so that the metal body of the medal and the ink have good adhesion.

After printing the edited image on the medallion by using a special inkjet type digital printing device, inspect the print quality such as the exact position and color, and the medallion without any abnormality is dried for 15-25 minutes at the temperature of 80 ℃ in the dryer. Production of color medals printed with colorful colors is completed.

When the adhesion and color of the ink to the color medal according to the present invention manufactured by the above method are exposed to direct sunlight and fluorescent light for a long time, the metal element inherent to each color gradually fades by reflecting the faded light due to oxidation and deterioration. Properties such as light resistance indicating the degree to be made could be confirmed.

First, the adhesion test (adhesiveness) of the ink layer was conducted by the test method specified in ASTM D-648-56 of the American Material Testing Association. After making a lattice at intervals of 1mm and attaching cellophane tape and detaching it again, a simple test was conducted several times to determine the adhesion force in the state of the removed grid and the state. It was confirmed that there was no adhesion between the ink layers.

Second, aging tester (Wheather-O-Meter) was used for color light resistance test, and the sample was judged to have good basic light resistance because there was no color change even after 50hr UV exposure.

As a result of testing the characteristics of the color medal according to the present invention, it was confirmed that the problem that the ink layer is separated or the color is easily changed in the future does not occur.

As described above, the color medal manufactured by the manufacturing method according to the present invention is a method of distinguishing a work of art such as a photograph or a painting by a method that is different from the conventional method in which the manufacturing method is manufactured in a limited color of about 1 degree to 6 degrees. Since the medals can be expressed in various colors, you can make your own medals and masterpiece series medals, which show your unique personality. Printing allows you to produce in large quantities, which not only produces them quickly, but also saves money.
