Laser marking is the permanent marking on the surface of various substances with a laser beam. The marking effect is to expose deep substances through the evaporation of surface substances, or "carve" traces through the chemical and physical changes of surface substances caused by light energy, or burn some substances through light energy to show the patterns and words to be etched
What are the differences between laser marking machine and traditional ink printing and their production applications.
From the perspective of production and application, it can be understood from six aspects: speed, efficiency, degree of use, difficulty of operation, potential safety hazards and market demand.
Efficiency: the laser has no consumables, eliminating the ink in silk screen printing. In the manual operation, the laser only needs to adjust the drawing file, while the silk screen constantly requires workers to pay attention to whether the screen is blocked, whether the printed graphics have sections, whether the screen surface is clean, and whether the external environment is clean and free of dust.
In terms of speed: from typesetting to logo forming, laser occupies an absolute advantage, getting rid of silk screen printing and pad printing, and from film making - plate making - weaving - drying - inking - fixture - printing logo.
Every step in the process can not go wrong. The process is much more complicated than you and I imagined. While the laser from mapping - typesetting - positioning - logo, the intermediate process as long as the two software, simple operation, low error rate.
Operation difficulty: the laser marking machine is easy to operate, and the silk screen printing operation needs to be careful. The laser operation requires learning the CDR and the operation software of the laser machine. The operation only needs to know the computer, and nothing else is a big deal.
In silk screen printing, you should first select the ink, select the color you want, get the color you want through a combination of one and multiple colors, and put the ink into the screen. In the process of use, you should devote yourself to it. For each part of the product printed, you should repeat several actions, such as the strength of the scraper, whether the screen is blocked, whether the screen is dirty, how much ink, and the evenness of the ink printed on the product.
In terms of the degree of use: silk screen printing still dominates the market. After all, it is an old brand. In the logo expression of many products, laser is not as colorful as silk screen printing. The single color of laser limits the development of laser in many industries.
Market demand: laser marking equipment is much larger than the current ink printing market demand due to its high processing precision, smooth marking and wide application range
Safety hazards: the laser belongs to the glare of strong light, and the ink belongs to the smell of gas volatilization. The laser will inevitably produce some smoke and dust when marking the logo, and the ink (component) will produce an odor in the process of blending and printing, which will do some harm to the body. However, the laser can solve this kind of problem by equipping an exhaust fan, and the silk screen printing can not effectively improve the whole working environment.
