3 algorithmsFloyd-Steinberg spreads error smoothly for photographic results. Atkinson produces high-contrast punchy output ideal for carving. Ordered (Bayer) gives a structured halftone pattern great for screen printing.
For linocut artistsUse Atkinson dithering in B&W mode with Pixel Size 2px or 4px. The larger pixels produce bolder dots that are easier to carve cleanly into a lino block. Adjust the threshold slider to control how much black vs. white appears.
Color ditheringReduce any image to a limited palette using Floyd-Steinberg or Atkinson color dithering. Set the bits per channel to control how many colors appear — 1-bit gives a stark two-tone effect per channel, 4-bit gives 16 levels.

For linocuts: try Atkinson + B&W. Bump Pixel Size to 2px or 4px for a bolder, easier to carve result.
