Halftone is the reprographic technique that simulates continuous tone imagery through the use of dots, varying either in size or in spacing, thus generating a gradient-like effect. Shown here are three examples of color halftoning with CMYK separations. From left to right: The cyan separation, the magenta separation, the yellow separation, the black separation, the combined halftone pattern, and finally how the human eye would observe the combined halftone pattern from a sufficient distance.Illustration: Pbroks13; SVG: Slippens
