Step 1: high-definition pictures
First prepare a high-definition photo (the pixel of the photo is too low to produce a good effect), import it into the Ezcad2 laser marking machine software, and then set the relevant parameters.
Step 2: Fix the DPI value
The higher the value of DPI setting, the better the marking effect and the slower the marking time. The commonly used setting values here are around 300-600, of course, higher values are also possible.
Step 3: Set photo parameters
In most cases, it is necessary to set the Invert and Dither for the photo (there will also be cases where the Invert is not selected, but it is necessary to set under normal circumstances).
If it is a material with color, check the Invert, such as a blue aluminum alloy phone case or a nameplate. If it is a material without color, such as natural steel, uncheck Invert.
Enter the Extend, check the Lighten. The Contrast adjustment is to control the ideal marking effect of the photo, the white area is not marked, and the black area is marked.
Scan Mode, here the Drill Mode is usually set to 0.5. Bidirectional scan is generally not recommended. It is too slow. It is not necessary to select Pixel power adjust.
Step 4: Set the power
In the right Mark parameter, speed is set to about 2000, the power is about 40 (the power is determined according to the material of the product, the power of 40 is set here for reference, and the power can be set higher if the phone case is marked.), the frequency is about 30. The higher the frequency, the denser the dots come out of the laser.
How can the laser marking machine mark the photos more clearly?
Normally, the higher the pixels of the selected image, the better.
DPI value is the key. To set the appropriate DPI value, generally 100~500. The larger the DPI value, the smaller the laser spot, and the finer the picture.
The power of the laser should also be set appropriately. The laser power is too high, and the image is whitened. The laser power is too small, the image is too dark, and more experiments should be done according to the actual effect.
Tips:
The laser marking machine is not a printer. Laser marking machine making picture is according to the resolution. The darker part of the picture is marked with a darker color, so not all photos can be marked.
