Laser marking is not limited to metal, plastic, or coated materials. In this test, a UV laser was used to mark an image onto a natural leaf surface. The goal was to check whether a delicate organic material could hold a clear image mark without obvious processing failure.
1. Test Goal
The goal of this test was to engrave an image onto a eucalyptus leaf using a UV laser marking machine.
This test focused on whether the laser could create a visible image effect on a thin, natural leaf surface while keeping the material stable during processing.
2. Test Requirement
The required process was image marking on a leaf sample.
The requested marking area was approximately 66 x 146 mm, and the test needed to evaluate whether the final effect was suitable for creative samples, craft decoration, or material application demonstrations.

5. Test Result
The image marking test was completed successfully, and the recorded result was good. The portrait image was clearly visible on the leaf, with recognizable facial details, tonal contrast, and the natural leaf veins still visible through the marked area.
The processing time was about 4 minutes.

6. Test Conclusion
This test shows that the UV-10 UV laser can be used for image marking on delicate natural leaf material. The result demonstrates that fine image details and tonal contrast can be produced on a thin organic surface while retaining the natural texture of the leaf.
This type of result may support botanical art, personalized craft samples, framed decorative pieces, creative gifts, and small-batch custom display products. Before batch production, the final parameter values should be confirmed with the same material, artwork file, lens setup, and marking software.
