Ordered dithering uses threshold maps to convert grayscale images into black and white patterns that simulate intermediate shades. The technique applies different threshold values across pixels to create visual patterns—the Bayer matrix arranges thresholds in a cross-hatch pattern to avoid artifacts, while larger matrices (4x4, 8x8) provide smoother transitions with more distinct patterns. Alternative arrangements like Cluster Dot matrices create newspaper-like dots, and Void and Cluster methods produce natural-looking blue noise textures. The visual guide demonstrates how threshold map arrangement directly determines the final dithering pattern.
