Laser engraving, also known as laser engraving or laser marking, is a surface treatment process using optical principles. It is often used on the keys of mobile phones and electronic dictionaries. It is engraved by the chemical and physical changes of the surface material caused by the light energy. according to the different engraving methods, it can be divided into dot matrix engraving and vector cutting.


Dot matrix engraving——Like high-definition dot matrix printing; the laser head swings left and right, engraving a line consisting of a series of dots each time, and then the laser head moves up and down at the same time to engrave multiple lines, and finally form a full page image or text.

Unlike dot matrix engraving, vector cutting is carried out on the outer contour of the graphic. This mode is usually used for penetrating cutting on wood, paper, acrylic and other materials, and can also be used for marking on a variety of material surfaces!

Laser engraving is a process of surface treatment, similar to silk screen and pad printing.  although they have similar visual effect but the price is different.

The following is a brief introduction to their differences:


①: For laser engraved products, fonts and patterns are light-transmitting; silk-screened products are opaque.


②: For laser engraved products, the color of fonts and patterns is the color of the material, and the background color is the color of the ink; silk-screened products are just the opposite of laser engraved products.


③: In terms of wear resistance, laser engraving is higher than silk screen printing


④: The principles used by the two processes are different. The optical principle used in laser engraving is only surface treatment, while silk screen printing is a physical principle, which makes the ink stick to it.


⑤: The price is different, but the price is still judged by the difficulty of the font and pattern.
