The early lettering buttons used mechanical lettering, and the sharpness of the handwriting and patterns were greatly limited. In particular, in the case of very fine letters or patterns, the definition was poor. Since the automatic laser engraving machine was developed in the early 1990s, this problem has been solved. The automatic laser cutting machine uses a computer-scanning drawing. No matter how complicated the pattern is, it can be easily engraved on the buttons. At the same time, the laser beam used for engraving can be as fine as a few tenths of a millimeter, so even a very fine handwriting or stroke can be clearly carved out. In the fashion industry, there are often many manufacturers that require their own company logos, logos, trademarks or other pictorial symbols. Therefore, the application of laser engraving technology has become more and more extensive. It reflects the development trend of the button industry in a certain period of time in the future.
