Why Dither?
1-bit graphics underpin everything from vintage Macintosh icons to modern risograph zines. The most popular algorithm, Floyd–Steinberg dithering, diffuses quantisation error across neighbouring pixels to mimic mid-tones with high fidelity—a trick first published in 1976 and still unbeatable for sharp, two-colour output.
Halftone dots scale beautifully on a screen-printing press, where each dot translates to a precise droplet of ink. Whether you're preparing artwork for vinyl cutting, laser engraving, or risograph printing, dithering gives you precise control over how your image translates to physical media.
