1 is an exemplary configuration diagram of a common name plate pre-printing the common design for each product according to an embodiment of the present invention, Figure 2 is a cross-sectional configuration diagram of the product name plate of FIG.

In order to manufacture a transparent substrate base color name plate capable of improving process efficiency in a small amount of product according to an embodiment of the present invention, as shown in FIGS. 1 and 2, a product name plate A is first provided.

Product name plate (A) according to the present invention is a product having a design and color different from each other in detail by product, but the name plate that is pre-printed on the transparent substrate 10 and the design and color that can be commonly applied to all products, and further laser By etching, the ink layer is formed on one or more layers or laminated prints on the transparent substrate 10 serving as a base so that the unique design and color of the product-specific details can be expressed.

To prepare a product common name plate (A) of the present invention as shown in FIG. 1 or FIG. 2, first, a transparent substrate 10 is prepared. The transparent substrate 10 may be glass, poly methylmethacrylate (PMMA), or polycarbonate resin (PC). Glass, which is one of the materials of the transparent substrate 20, is preferably tempered glass, and the other, PMMA, is a material having excellent light resistance and transparency.

And the thickness of the transparent substrate 10 according to the present invention is preferably 0.3mm ~ 1.2mm.

In the present invention, the color ink layers 12, 14 and 16 of the common design for each product are printed by a silk screen printing method so as to improve the process efficiency in the product produced in a small amount on the prepared transparent substrate 10. Print formation is performed, but the base color ink layer 12 is printed on the rear surface of the transparent substrate 10, and one or more color ink layers 14 and 16 are singly or laminated on the front surface of the transparent substrate 10 in accordance with a common design. The product name plate A is obtained by forming.

As the color of the background color ink layer 12 printed on the back surface of the transparent substrate 10, for example, white is preferable as shown in FIG. When the white color becomes the background color, a character or a symbol including a number in the detailed expression for each product is good as the background color when it is expressed through the transparent substrate 10. The background color of the background color ink layer 12 may be formed by printing in red or other colors, and may be formed by printing different colors by dividing the areas. Multi-layer printing may be formed in multiple colors.

The color ink layers 14 and 16 printed on the front surface of the transparent substrate 10 are red ink layers 14 and black ink layers 16 as examples of the vehicle instrument name plates shown in FIGS. 1 and 2. Consists of.

As shown in FIG. 2, when the color ink layers 14 and 16 are laminated on the entire surface of the transparent substrate 10 for the purpose of individualization by product by a common design configuration and laser etching, red ink is formed on the first layer. The black ink layer 16 is formed in the layer 14 and in the two layer portions, and the black ink layer 16 is formed in the case of being formed alone in one layer.

When the red ink layer 14 and the black ink layer 16 are formed on the entire surface of the transparent substrate 10, both the red ink layer 14 and the black ink layer 16 are etched as in the "X" region. Thus, the white color of the background color ink layer 12 positioned on the rear surface of the transparent substrate 10 may be used to expose the white ink layer, and only the black ink layer 16 may be etched as in the "Y" region to etch the red ink layer. 14 may be used for the purpose of revealing, and may also be used for the purpose that the black of the black ink layer 16 remains as it is not etched at all.

In the case where the black ink layer 16 is formed as a single layer on the entire surface of the transparent substrate 10, the black ink layer 16 is etched in the form of numbers, symbols or letters as in the "W" region, thereby inherent in the product. It can be used for the purpose of expressing the individualization information of the white color of the background color ink layer 12 located on the rear surface of the transparent substrate 10 as the information display background.

In addition, there are regions in which the ink layers 14 and 16 are not formed by the shape of the common design. In particular, the white circular band design shape of the speedometer or tachometer indicator of the vehicle instrument name plate shown in FIG. 1 is a transparent substrate 10 of which the white color of the ground color ink layer 12 printed on the back of the transparent substrate 10 is displayed. Since it is exposed through), the ink layers 14 and 16 are not formed on the front surface of the transparent substrate 10.

The thicknesses of the ink layers 12, 14 and 16 according to the present invention are 3 to 10 mu m. If the thickness of each ink layer 12, 14, 16 is less than 3 mu m, laser etching is very difficult and excessive etching may occur, and if the thickness exceeds 10 mu m, not only excessive time is required for laser etching but also each ink The critical significance is that the print formation of layers 12, 14 and 16 is difficult to achieve in one step.

After the product name plate A is prepared as described above, the product name plate A is partially laser-etched according to the individual products as shown in FIG. 3 to complete the individualized name plate B of FIG. 4.

That is, in order to make the product name plate A prepared as shown in FIGS. 1 and 2 separately, wavelengths different for each ink layer color in the product individualization target areas W, X, and Y on the front surface of the product name plate A. Each laser in the range is etched to obtain a product personalization name plate (B) representing the design and color of the individual product.

The wavelength range of the laser used for laser etching according to the present invention is 300 to 1100 nm, and the ink layers 14 and 16 of the corresponding color are etched with a laser having a different laser wavelength for each ink layer color within the wavelength range. do.

Figure 3 is a cross-sectional configuration for performing laser etching for each region according to the product specifications according to the present invention, Figure 4 is a name plate configuration produced by laser etching in accordance with an embodiment of the present invention.

As shown in FIG. 3, in the present invention, when the black ink layer 16 is laser-etched, the black ink layer 16 is etched by a laser LSR1 having a wavelength in the 900 to 1100 nm band, and the red ink layer 14 is etched. In the case of laser etching, etching is performed using a laser (LSR2) having a wavelength in the 400 to 700 nm band.

In the present invention, when the black ink layer 16 is etched by the laser (LSR1) having a wavelength of 900 to 1100 nm, the etching may be performed faster than other wavelengths (relatively short wavelength) within 300 to 1100 nm. The inventors of the present invention confirmed that the thermal effect on the red ink layer 14 was etched with a laser (LSR2) having a wavelength in the 400 to 700 nm band, thereby making soft etching and slow etching than the laser (LSR1). However, the inventors have confirmed that deterioration of the red ink layer 14 is minimized.

Referring to Figures 3 and 4 will be described in more detail a method of performing laser etching for each region according to the product specifications in the present invention as follows.

As shown in FIG. 1, individual product-specific alignment is performed by laser etching from a common design configuration, and a black ink layer on the front surface of the transparent substrate 10, as in the "W" region shown in FIG. In the case where the single layer 16 is formed in one layer, the transparent substrate surface 10s is exposed by etching the black ink layer 16 on the front surface of the transparent substrate 10 using a laser LSR1 to etch a number, a symbol, or a letter form. do. Accordingly, the product-specific individualization information is clearly expressed by the white of the background color ink layer 12 positioned on the rear surface of the transparent substrate 10 as the background.

And, in the "X" region in which the red ink layer 14 and the black ink layer 16 are formed in multiple layers on the front surface of the transparent substrate 10, in Figure 3 (b) for individualization by product by laser etching. When the black ink layer 16 and the red ink layer 14 are both etched to expose the transparent substrate surface 10s, the black ink layer 16 and the LSR1 and LSR2 suitable for the black and red colors are sequentially used. The red ink layer 14 is sequentially etched. Accordingly, the white of the background color ink layer 12 formed on the rear surface of the transparent substrate 10 is clearly displayed while the transparent substrate surface 10s is exposed.

Also, in the "Y" region where the red ink layer 14 and the black ink layer 16 are formed in multiple layers on the front surface of the transparent substrate 10, as shown in FIG. Likewise, when only the black ink layer 16 is etched to expose the red ink layer 14, only the black ink layer 16 is etched using LSR1 suitable for the black color. Accordingly, in the etched " Y " region, the red color by the red ink layer 14 is expressed with the design.

When the laser etching according to the corresponding region according to the product specification in the present invention in the same manner as in Figure 3 (that is, etching using a laser having a different wavelength for each color of the ink layer) by product as shown in FIG. By completing the production of the individualized name plate (B) of the product of individual colors designed to show the unique features of the unique features, in the present invention, it is possible to improve the process efficiency in the product produced in small quantities.

The product individualization name plate (B) as described above is completed as a finished product by the perforation or cutting of unnecessary parts.

In the above description of the present invention, the ink layer stacking is formed on the front surface of the transparent substrate 10 and the specific embodiments of etching with lasers having different wavelengths for different colors are described. However, the ink layer stacking is formed on the rear surface of the transparent substrate 10. And etching with lasers of different wavelengths for each color can be further formed as well, and various modifications can be made without departing from the scope of the present invention. Therefore, the scope of the present invention should not be defined by the described embodiments, but should be defined by the claims and their equivalents.
