Color Depth
Visual representation of grayscale depth engraving
Below you can see an example of a color image that has been converted to grayscale.
Next, we take that image and engrave at 300 DPI | 100 Power | 60 Speed | Stucki Dithering.
Grayscale
Engrave depth range is important for a user to understand. Please note the depth range of a project is separate from suggested material settings. Suggested material settings relate to the material used; however, the depth range indicates detail from how many layers your final project requires.
...
- More Black = deepest engrave
- Gray Tones = medium engrave based on channel depth and depending on grayscale bit level: 1,2,4,8,10 bit
- White = does not touch/engrave
Dithering
Dithering your file can result in a better overall image. This depends on material, settings, and file detail. Dithering may be done via photo editing software such as Affinity or Photoshop. The Epilog Dashboard also has dither patterns that can be selected when sending your file. A dither is not required for all engrave projects. As with most laser cutting, we recommend testing your file prior to doing a final pass.
