Use a relief depth map in LightBurn
A depth map describes height, not a laser power table. Download the original 16-bit PNG; the webpage thumbnail is an 8-bit preview, not the production source.
Import and confirm tonal direction
After importing the PNG, check its dimensions and which regions are dark or light. Grayscale values do not directly specify physical engraving depth. Material, equipment, scan mode and software processing affect the result; test any inversion on a small image.
Choose an appropriate image mode
LightBurn grayscale varies power, while dithering represents tone through dot patterns. These modes serve different purposes and neither guarantees a calibrated relief height. Read the mode guidance for your device; do not assume the complete 16-bit input precision survives every processing stage.
Test material before the full image
Use LightBurn’s material test to compare settings, then inspect a small image for detail and tonal direction. This site supplies no universal power, speed or pass count. Record your equipment and material tests instead of copying another machine’s settings.
