Engraved designs
- [Instructor] We've talked a little about what engraving is, but to review, laser engraving only partially penetrates through the material. By burning away only thin layers, engraving can be done on a wider variety of materials than through cutting. Because you can set up the laser to burn at different settings, you can achieve both visual and physical depth. Engraving is especially suited for decorative designs and signage because it won't peel off, fade, or smudge. There are two main styles of engraving, sometimes used in the same file. Raster engraving of data like text and shapes with sharp edges uses vector data to engrave large areas to the same level of depth. The aim of this is to have a consistent depth or darkness of burn rather than a gradient effect. Vector art can be broken into blocks where each color can be assigned a different burn setting.
