Hand board surface treatment process ④: Radium Carving

Laser engraving, also known as laser engraving or laser marking, is a surface treatment process based on the optical principle. It is mostly used on the keys of mobile phones and electronic dictionaries. It carves traces through the chemical and physical changes of surface substances caused by the light energy of laser beam, or burns some substances through the light energy to show the graphics and characters to be etched.

According to different engraving methods, it can be divided into dot matrix engraving and vector cutting.

1. Dot matrix engraving: similar to high-definition dot matrix printing; The laser head swings left and right to carve a line composed of a series of points each time, and then the laser head moves up and down at the same time to carve multiple lines, and finally form a full page image or text; The scanned graphics, text and vectorized graphics and texts can be engraved with dot matrix.

2. Vector cutting: different from dot matrix engraving, vector cutting is carried out on the outer contour line of graphics and text. This mode is usually used for penetration cutting on wood, paper, acrylic and other materials, and marking can also be carried out on the surface of a variety of materials!

The products produced by radium carving and silk screen printing have the same visual effect from the appearance, but there are still great differences in practice. The following is a brief introduction to their differences:

1. Radium carving products, fonts and patterns have light transmittance; Silk screen printing products are opaque.

2. For radium carving products, the color of font and pattern is the color of material, and the background color is the color of ink; Silk screen printing products are just the opposite of radium carving products.

3. In terms of wear resistance, radium carving is higher than silk screen printing

4. The principles of the two processes are different. The optical principle used in radium carving can be used for surface treatment, while silk screen printing is a physical principle, which allows the ink to adhere to it.

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