There will be many problems in the process of using the marking machine. Sometimes we need to print pictures, but there may be cases where the printed pictures are not clear enough. How to deal with it at this time? Let us analyze the unclear patterns marked by the laser marking machine. solution.
1. The laser marking pattern is dim and unclear, we can consider key and material issues. Guangzhou laser marking machine also has high requirements on materials. This will happen again if the material is within the marked range. In this case, the effect is mainly due to the darkening due to the reflection of some material; or because the laser is out of focus, just like a camera taking a picture, the out-of-focus picture is of course not clear; for the same reason, The laser beam and camera need to be adjusted in focus.
2. The laser marking pattern is partially unclear, due to the uneven thickness of the medium, the uneven forming pressure, or the uneven temperature, and the machine adjustment accuracy is not enough; the general laser processing process control requires the marking error to be within 0.001mm, and the hardness to be maintained at 230N /mm or so. The surface pattern marking is marked by a certain laser beam. If the horizontal position is not flat, or the machine sets the theme, it will cause the problem that the marking part is not clear.
3. The marking pattern will be different from the actual setting. It depends on the tuning of the machine. The marking is done by evaporating the surface of the medium by means of a beam of light. If there is a gap in the beam itself, you can only adjust the machine first. When adjusting the laser beam, you can use the adjustment plate to correct components such as the vibrator.
4. The marking pattern effect is whitish; this has a lot to do with the material, and the solution can refer to the first one.
5. We adjust the dpi value of the pattern, this value is the meaning of the pixel, this is generally 300, we can set it higher, but it will affect the speed.
6. You can set the inversion, we set the inversion of the picture in the expansion. Try to see if it becomes clearer.
Combining the above methods, it is definitely possible to mark the pattern photos clearly. The specific method needs to be tested to know which method is suitable for you.
