The so-called laser etching is the use of laser engraving technology to burn black grooves on the keycap. Because the traces of the engraving are linear, the arrows on the common laser-etched keyboard are hollow.
The many white keyboards on the market basically use this keycap technology. The main reason is that the manufacturers have low cost. Although the production line is expensive, its daily output is more than ten times that of other printing methods. Burned handwriting, so you don’t need any other measures to have a clear and solid handwriting. Another reason for its large scale is that it is more environmentally friendly and does not produce harmful products.
But laser etching also has several fatal flaws, which also determines that it can not be used in the production of high-end keyboards. First of all, since laser etching is etching and no ink is used, only a single black font can be printed, so that the multi-color overprint design often found on high-end keyboards cannot be achieved; secondly, the high-end keyboard is designed for For the durability, most of the non-white color design is used, and the wear-resistant filler is added to the key cap material, but due to the self-characteristics of laser etching, it is used in non-white and keyboards with other fillers. The ideal clear writing cannot be etched on. Finally, the structure and programming of the laser etching machine make it the best keyboard for standard key design. The non-standard structure of ergonomics is difficult to use on ordinary laser etching machines. Printed out. For this reason, laser etching is only used in the middle and low-end production lines to take advantage of its high production speed and low cost in the production line of Dachang. In the high-end production line, due to higher printing quality. Requirements, so only traditional high-cost ink printing methods can continue to be used.
