There are many ways to achieve color printing with a laser marking machine, but it also requires certain materials such as stainless steel. Color printing is usually done by adjusting the pulse width, so there is a method on the market specifically designed for laser marking machines. designed for color printing. Regular laser marking machines can also print some colors. Next, Nevermore Laser will explain to you how a laser marking machine prints colors.
1. Conventional fiber laser marking machines require various parameters to be adjusted for color printing. The main parameters that need to be configured here are Fill, Speed, Power and Frequency. Our commonly used options are to change the padding to 0.02. Line spacing, speed are changed to 200, power is changed to 90. When we hit again at this time, we will find that the hit is very deep. This is definitely wrong. We also need to change one parameter - change the focal length manually. We increased the height of the marking machine to two centimeters, which should add two centimeters to the positive focal length. At this point, if we need different colors, we will gradually increase the number of millimeters. Can be reduced to 1.5 cm. You can also lower it by one centimeter and slowly adjust it to achieve different effects. This is how regular marking machines print colors.
2. The second type is the use of a machine specialized in color printing, which we often call mopa laser marking machine. This type of machine can mainly adjust the pulse width and realize the laser color according to the pulse width. In terms of effect, the effect of this machine is much better than the previous one. But in terms of cost, such a machine is more expensive than the one described above.
In fact, color printing is only compared with stainless steel materials. Printing colors on other materials is almost impossible, and color printing also has relative distortion. Therefore, the editor of Juchuang Laser personally believes that this process is actually not ideal. .There are disadvantages. During processing, it is obvious that the marking speed is very slow. If you want to use this process, it depends on whether the production volume is too large or whether you can accept the distortion effect.
