This test used a UV-10 UV laser to mark grayscale image designs onto slate stone samples. The goal was to check whether the material could show clear image contrast and surface detail after laser marking.
1. Test Goal
The goal was to verify whether the UV laser could produce visible image marking effects on slate stone.
The test focused on grayscale image detail, edge definition, and whether the marked design could remain clear on the rough stone surface.
2. Test Requirement
The required process was image marking on slate stone.
The sample needed to show recognizable image details, including graphic contrast and fine visual texture, using the available UV laser setup.

5. Test Result
The image marking test was completed successfully, and the recorded result was good. The slate samples showed clear grayscale contrast, visible image details, and readable decorative graphics on the stone surface.
The processing time was about 6 minutes and 40 seconds.
6. Test Conclusion
This test shows that the UV-10 UV laser can create detailed image marking effects on slate stone. The result demonstrates clear contrast and decorative image detail on a naturally textured surface.
This application may be useful for custom stone coasters, decorative plaques, craft products, personalized gifts, sample validation, and small-batch stone product customization. Before batch production, the final parameter values should be confirmed with the same material, artwork file, lens setup, and marking software.
