Halftone dots are the invisible architecture behind every printed photograph. In AM (Amplitude Modulated) screening—the traditional method—dots vary in size while maintaining fixed spacing. Darker tones = larger dots. Highlights = tiny dots. The pattern matters. Four color screens (CMYK) are rotated at specific angles—typically Cyan 15°, Magenta 75°, Yellow 0°, Black 45°—to prevent moiré interference between overlapping dot grids. Screen frequency is measured in LPI (lines per inch): • Newspapers: 85 LPI • Magazines: 133–150 LPI • Fine art prints: 200–300+ LPI Lower LPI = bolder, more visible dots. Higher LPI = smoother tonal transitions but requires higher resolution plates and paper. Next time you pick up a magazine, grab a loupe. The entire image is just dots.
