Laser etching of foam substrate. |
| 摘要 |
<p>A foam plastic substrate has an image formed on its surface by differential ablation by a laser. A composition is applied to the surface in the shape of the image to be formed and has an ablation rate different to that of the foam substrate. After irradiation of the surface, the image is formed in relief on the surface.</p> |
