{Manufacturing Method of Precious Metal Cards}

The present invention relates to a method of manufacturing a precious metal card used for business cards, cards, commemorative plaques, awards, etc., and more specifically, to a method of manufacturing a precious metal card by setting a printing area on a precious metal plate and printing and coating only the printing area.

A plaque, commemorative plaque, or appreciation plaque is produced to commemorate a special event. It is generally made by printing or engraving various phrases and pictures on the front, and is produced using various materials such as metal plate, glass, crystal, and wood.

Recently, metal plates are made using advanced precious metal materials such as gold, silver, and platinum to create more beautiful appearances and collectible plaques, commemorative plaques, appreciation plaques, and cards. However, since the metal plate is metallic, content or pictures cannot be printed on the surface, so a method of attaching film paper to the surface and printing on it was used. However, the film peeled off from the metal plate, making it difficult to store for a long time. There are difficulties.

In order to solve the above reason, Utility Model Registration No. 20-160239 discloses a technology of coating transparent vinyl paper on the upper and lower surfaces of a precious metal thin plate, printing a pattern on an OHP film, and attaching the printed OHP film to a metal plate. However, as time passes, the metal plate and the printed film peel off and the color of the printed area on the OHP film becomes discolored.

In order to solve the above problems, Patent Registration No. 10-401925 applies heat to the surface of a precious metal sheet to heat treat it to maintain a flexible state, and prints various patterns or letters on printing paper using a laser printer. The display content is printed, and the printed paper is placed on the surface of the precious metal sheet and rolled into an intaglio. The first coating process involves coating the front and back of the precious metal sheet with thin transparent vinyl paper, and various characters are placed on one surface. A technology is disclosed that consists of a secondary coating process in which a thin film paper printed with another display such as a pattern or a pattern is placed and then the top and bottom are coated with transparent vinyl paper. However, this technology has a complicated process, there is a problem in that the printed coated paper peels off, and the precious metal plate is coated in multiple layers with printed paper and coated paper, so the texture of the precious metal cannot be sufficiently felt.

The present invention's precious metal card manufacturing method includes a precious metal plate manufacturing step (S10), a printing step (S20), and a coating step (S30). The precious metal card manufacturing method is characterized in that primer application, printing, and coating are performed on the printing area 13 of the precious metal plate 11, thereby improving the durability of the precious metal card and allowing the color and texture of the precious metal to be felt as is. .

The precious metal plate manufacturing step (S10) includes a precious metal plate processing step (S11), an inspection step (S12), and a cutting step (S13). In the precious metal plate manufacturing step (S10), precious metals with high malleability such as gold, silver, and platinum are processed to become the precious metal plate 11.

In the precious metal sheet processing step (S11), the precious metal is rolled and processed into a precious metal sheet using a cold rolling or hot rolling method. The precious metal plate may have a thickness of 1 to 100 μm.

The inspection step (S12) includes a precious metal plate surface photographing step (S12-1), an analysis and determination step (S12-2), a reprocessing count checking step (S12-3), a reprocessing step (S12-4), and a defective area display step. Includes (S12-5). The precious metal sheet inspection step (S12) is characterized by inspecting the appearance of the surface of the precious metal sheet processed in the precious metal sheet forming step (S11) and reprocessing defective areas to minimize defects in the precious metal sheet (11).

In the step of photographing the surface of the precious metal sheet (S12-1), the camera photographs the surface of the precious metal sheet and transmits it to the control unit.

In the analysis and determination step (S12-2), the control unit analyzes the data transmitted in the precious metal sheet photographing step (S12-1) to determine whether the precious metal sheet is defective. The control unit measures the contrast value for each pixel based on the data and compares it with the contrast value of the existing normal surface to determine defective products. The contrast value is measured higher than the normal contrast value when there are protruding parts such as protrusions on the surface, and is measured lower than the normal contrast value when there are depressions such as grooves. The control unit designates an area where the brightness value is different from the normal brightness value as a defective area. A precious metal plate containing the defective area is judged to be defective. If the precious metal sheet is determined to be defective, it is moved to the reprocessing count confirmation step (S12-3) (at this time, the precious metal sheet determined to be normal is moved to the cutting step (S13)).

The reprocessing count confirmation step (S12-3) confirms the reprocessing number of the precious metal sheet determined to be defective in the analysis and determination step (S12-2). If there is no record of reprocessing of the precious metal plate, it is moved to the reprocessing step (S12-4) to reprocess the defective area. If the precious metal plate has more than one reprocessing record, it no longer goes through the reprocessing step (S12-4) and moves to the defective area display step (S12-5) for use after excluding the defective area from the cutting area.

In the reprocessing step (S12-4), defects are removed by reprocessing the precious metal sheet that has not been reprocessed in the reprocessing count checking step (S12-3). The precious metal plate is subjected to heat treatment and pressure on defective areas to remove defects. The precious metal sheet from which defects have been removed in the reprocessing step (S12-4) undergoes the inspection step (S12) again from the precious metal sheet surface photographing step (S12-1).

The defective area display step (S12-5) displays defective areas of the precious metal sheet that have been reprocessed more than once in the reprocessing count checking step (S12-3). The precious metal sheet with the defective area marked moves to the cutting step (S13).

The cutting step (S13) includes a cutting position setting step (S13-1) and a cutting step (S13-2). The cutting step (S13) is characterized in that the waste of the precious metal sheet is minimized by determining and cutting the maximum area that can be processed from the precious metal sheet to the precious metal sheet 11.

In the cutting position setting step (S13-1), the control unit sets the cutting position of the precious metal sheet that has passed the precious metal sheet inspection step (S12). The control unit receives size data of the precious metal plate and size data of the precious metal plate 11 to be produced. The control unit compares the input data with DB data and sets the cutting position of the precious metal sheet. If there is a defective area in the precious metal sheet, the control unit minimizes the wasted area of the precious metal sheet. The control unit sets the cutting position by setting the maximum area that can be processed with the precious metal plate 11, excluding defective areas. At this time, the precious metal plate 11 can be made in various sizes, and the precious metal plate 11 of the size required for production, which was previously input to the control unit, is made.

In the cutting step (S13-2), the precious metal plate 11 is formed by cutting at the cutting position set in the cutting position setting step (S13-1). The cutting is additionally performed with a chamfering operation, so that the side surface of the precious metal plate 11 can be formed smoothly.

The printing step (S20) includes a printing area setting step (S21), a printing area scratch forming step (S22), a primer application step (S23), a primer drying step (S24), and a UV printing step (S25). The printing step (S20) is characterized in that a printing area (13) is set on a part of the precious metal plate (11) processed in the precious metal plate cutting step (S13) and a printing process is performed only in the set printing area (13). do.

The printing area 13 is characterized by being set to an area 2 to 5 times the area of the printing layer, with margins on the top, bottom, left, and right around the printing layer 17.

The print area scratch forming step (S22) forms a scratch 14 in the print area 13 of the precious metal plate 11 set in the print area setting step (S21). The scratch 14 increases the adhesive force by increasing the adhesive area and friction between the precious metal plate 11 and the primer layer 15. The scratches 14 are formed on the surface of the printing area 13 using a metal abrasive. The scratch 14 is formed to have a thickness of 1 to 10 μm.

The primer application step (S23) is characterized in that a primer for metal printing is applied to the print area (13) where scratches were formed in the print area scratch formation step (S22) to form a primer layer (15). The primer for metal printing may be composed of a metal powder composed of magnesium or aluminum in an epoxy resin, and a nanopowder composed of one or a mixture of two or more of zinc oxide, magnesium silicate, magnesium oxide, antimontine oxide, tungsten, and bronze. there is.

The coating step (S30) forms a coating layer (19) on the printed layer (17) to protect the printed layer (17) formed in the UV printing step (S25).

In the printing area coating liquid application step (S31), the coating liquid is applied to the printing area 13 to form a coating layer 19. The coating layer 19 is characterized in that the durability of the precious metal card is improved because the adhesive strength of the portion directly in contact with the primer layer 15 is increased. The coating liquid is characterized by preventing contamination of the coating layer by using an anti-contamination composition to prevent contamination such as fingerprints or oil films. The coating solution is applied to a thickness of 0.5 to 100 μm to form a coating layer 19. The anti-fouling composition can be formed by adding 1 to 5 g of sodium tetraborate, 0.07 g of sodium dodecylbenzenesulfonate, and 1 to 20 g of mannitol to distilled water to prepare a 1L solution and then stirring for 5 hours.
