Which color is the best for laser coding?

The material is black, and the less surface gloss it has, the easier it is to absorb light and heat, making engraving and processing easier. Basically, the closer the color is to white and the more glossy it is, the greater the reflectivity of light will become. On the contrary, the more black materials that can absorb light, the less glossy they are, and the lower the reflectivity of light becomes. The darker the color of the same material, the better the laser coding effect.

The depth of color can also affect the reflectivity of light. The basic idea is that the darker the color, the easier it is to engrave and process, while the lighter the color, the more difficult it is. The coordinate curves in white, gray, and black are basically distributed in a horizontal shape. This means that no matter how long the wavelength of light is, reflection will still occur. However, the reflectivity varies, and white reflects almost all the light. The impact of product material and color on the coding effect is a challenge that laser coding cannot avoid. Jiruixiang Laser recommends that the product equipment should be based on the principle of first testing samples, combined with the production line situation for dynamic coding testing, and select the appropriate model to see the effect in real time.
