Since the laser marking machine is a marking (carving, engraving, coding) equipment that does not require consumables, the color marked on the object is generally based on the material of the marked workpiece, the model used, and It depends on the auxiliary materials and the adjusted parameters, not what color you want to be able to print out what color.

Next, please come and learn with Foshan Fulan Laser: What are the main factors that affect the color marked by the laser marking machine.

1. The laser wavelength characteristics of the laser marking machine. Different laser wavelengths will react to different materials with different colors. For example: laser marking on ABS plastic, using CO2 laser to mark out-focus yellow, using optical fiber or semiconductor to mark out gray-black, and using ultraviolet or green laser marking machine to make out-of-focus black.

2. The characteristics of the laser spot. Generally speaking, the closer the laser spot is to the fundamental mode, the clearer and brighter the marking color will be.

3. The quality of the optical focusing lens used in the laser marking machine. The beam expander multiples, the better the quality of the field lens, the better the marking effect will be.

4. The frequency of the laser marking machine is different, the marking effect will be different. Some laser marking machines cannot be adjusted to a very high frequency, and some can be adjusted to a very high frequency, so that the color of the marking will also be have difference.

5. When the speed and power are adjusted differently in the laser marking process, there will be differences in color.

6. In the laser marking process, the marking effect of the forward focus and the defocus is also related. For example, if you want to make a black effect on stainless steel, in addition to using semiconductor and fiber laser marking machines, you also need to adjust to a slower speed, lower energy, and higher frequency. A certain amount of positive defocus can be used for processing to achieve a multiplier effect with half the effort.

7. The effect and color of the marking are also different for the impurities of the processed items.

8. The temperature influence of the processed items.

9. The processed item is covered with a layer of film, and the color of its marking will be different.

10. To make signs with some special materials, some special equipment and some setting skills can be used to produce excellent results. For example, a MOPA machine is required to make a black logo on metal anodized aluminum. The mopa laser engraving machine has a wide pulse width and pulse frequency adjustment range. Using narrow pulse width and high frequency parameters, different depths can be printed on the surface of the alumina material. Black effect, fine and beautiful, no less than silk screen. There are also some plastic materials for blackening, which requires an ultraviolet laser marking machine and so on.
