A laser is a kind of light. Like its electroluminescence in nature, it is produced by the transition of atoms (molecular or ion kites) and is caused by spontaneous radiation. Advertising is an applied explanatory text, which is a main method of introducing business products to consumers or clients, reporting service content or entertainment programs. How can these two things that seem to be irrelevant to each other come together? But science is like this. In fact, laser technology has been applied in depth in light, sound, electricity, etc., and laser technology in the advertising industry has been developed in China in recent years. Since laser processing technology is a product of high-tech fields, and advertising is an information product that is extended by the market, the organic combination of the two can definitely play the role of advertising. At present, the processing method of laser in advertising is embodied in engraving and cutting; the main processing industry refers to the printing of signage in advertising, the engraving and cutting of two-color plates, the cutting of plexiglass, the cutting and engraving of wood boards, etc. . The principle of laser engraving and cutting Although the laser is light, it is obviously different from ordinary light. The laser only depends on spontaneous emission in the initial very short time. The subsequent process is completely determined by the excitation radiation, so the laser has a very pure color. Almost no divergent directionality, very high luminous intensity. At the same time, the laser has high coherence, high strength and high directivity. After the laser is generated by the laser, it is transmitted by the mirror and irradiated onto the processed object through the collecting mirror, so that the processed object (surface) is subjected to strong heat energy and the temperature is sharply increased. This point is rapidly melted or vaporized due to high temperature, and the trajectory of the laser head is used to achieve the purpose of processing. After the laser is generated, the grinding is less, the waste is less, and the flexible layout of the computer reduces the waste space; the operation is simple, and the general production enterprises have their own professional software developed. The application of laser engraving and cutting machine in the advertising industry The application of laser processing technology in the advertising industry is mainly divided into three working modes: reef engraving, cutting, engraving and cutting. For each working mode, we have some inexhaustible in the operation process. The same place. Engraving: mainly on the surface of the object. We first process the graphics we need to engrave and convert them into BMP format in PHOTOSHOP, and then open the graphics file in dedicated engraving and cutting software. According to the materials we have processed, we can set the appropriate parameters, and then click on the run, the engraving machine will engrave according to the lattice effect produced by the graphic file. In the advertising industry, it is mainly used for the processing of wood, two-color board, plexiglass, color paper and other materials. Cutting: We can understand that it is the separation of the edges. For such processing purposes, we should first make the graphics into lines in CORELDRAW, AUTOCAD, and then save them in the corresponding PLT, DxF format, open the cutting operation software to open the file. According to the materials we processed, the parameters such as energy and speed can be set and then run. After receiving the instructions from the computer, the cutting machine will automatically cut according to the flight route generated by the software. In the advertising industry, it is mainly applied to the processing of wood, two-color board, plexiglass, color paper and other materials, making crystal characters, three-dimensional trademarks and so on.
