This is ok for general use, but works best for images with large areas of solid fill, where diffusion dithering can cause unwanted artifacts (see below).
Ordered: Also called ordered dithering, this is a step above threshold for grayscale images, and uses densely packed on/off dots to approximate shading, using an ordered/regular grid pattern. Don't use this mode for grayscale or color images. This should only be used for images that are two-color black/white to begin with, like an image you dithered outside of LightBurn. 
Threshold: a simple on / off switch if the image is dark / bright at a given location. Image ModeĬhanging the image mode will change the algorithm used to prepare the image for engraving. DPI (dots per inch) is just 25.4 / interval. See Line Interval under Operations Scan AngleĬontrols the pixel density of the output - this is simply another way of representing line interval that is more intuitive for some. See Overscanning under Operations Line Interval This is useful for engraving slate or glass, where burned areas become lighter. This will invert your image during engraving. See Bi-Directional Scanning under Operations Negative Image Modeĭisabled for raster images Bi-Directional Scanning If your image does not have absolute black or absolute white then it will not ever fire at the min/max settings. Increasing this value beyond your lasers firing threshold will allow the laser to fire for absolute white.Ī note on Min/Max power: This scale affects the entire range from white to black. The minimum power of the laser for pure white. Setting this to a lower value will decrease the power of the laser when engraving absolute black.

LightBurn has the ability to engrave raster images (photo engrave) without additional effort.
