Dots, or other patterns used to impart the illusion of tonality on an image, will grow when put onto printing materials, causing the visual effect of larger patterns. The amount of change, measured in percent, is the dot gain. It is greatest in the mid-tones of an image, and is absent from both he shadow and the highlight end of the tonal scale.
