Laser Engraving Gray Scale|Gray-Scale Laser Marking

Mastering grayscale image processing technology is the key to improving the quality of laser marking.The book explains how to use image processing, laser power and speed, and other parameters to achieve a perfect reproduction of the pattern on metals, plastics, and other common materials.It includes practical techniques for converting a Photoshop image to a grayscale image, a comparison chart of marking machine parameters, and optimized solutions for problems such as blurry edges and insufficient contrast.

The laser engraving industry often faces the problem of converting gray-scale images to engravable files.First, the user must understand that the light and dark tones in a grayscale image directly determine the distribution of laser energy--lighter tones correspond to higher power, darker tones to lower power to prevent burning.The basic operations of threshold adjustment and contrast enhancement can be done using Photoshop or professional software for screen printing, but in practice one often encounters problems of detail loss or jagged edges.

For different materials, different parameters are required. For metals, it is recommended that a high frequency and low power be used to avoid oxidation and yellowing. For acrylic, a medium speed and high power is suitable to ensure transparency.Our tests showed that if the original image is converted to 8-bit grayscale, the dithering algorithm can effectively improve the problem of color banding.When exporting a file, it is important to match the file's DPI to the laser machine's optical accuracy. For best results, 600 DPI images should be used with a 0.01 mm laser spot.

Common mistakes include over-reliance on automatic parameter setting. In actuality, one should combine material samples with three-stage testing: first using 30 % power to mark the outline, 50 % to ensure the main depth, and finally 80 % to reinforce the key areas.In an example of the technology's use, after sharpening a gear pattern to be marked on an aluminum surface, the sharpness of the teeth was improved by 40 %.Finally, it is important to remember to regularly calibrate the laser's focal point, and to reset the parameters when the ambient temperature changes by more than 5 ° C.

The Best Combination of Laser Power and Speed: A Comparison of 20 Sets of Data

After analyzing 20 sets of test data, the company determined the best combinations of laser power and processing speed to use for cutting and engraving metals. This helped users quickly find the optimal settings to achieve a balance between efficiency and quality, avoiding the material waste and equipment wear that can result from blindly fiddling with settings.
