What does halftone mean?
A halftone is a technique for reproducing an image by using regularly arranged dots to imitate continuous variations in light, shade, and color. Smaller, more densely packed dots appear darker, while larger or more widely spaced dots appear lighter. The method became especially important in newspaper and magazine printing, where it allowed photographs and detailed artwork to be printed using the same limited inks as ordinary text. In digital imaging and visual art, a halftone effect can also imitate the appearance of printed mass media. As a noun, halftone may refer to the process, the resulting image, or the dot pattern itself. It can also function as a verb, meaning to reproduce an image through this process, and as an attributive modifier, as in “halftone screen.” The word is best known for the way a small pattern of dots can create the illusion of a photographically continuous tone.
An image, printing process, or visual effect that uses dots of varying size or density to reproduce continuous tones of light and shade.

The regular plural refers to multiple halftone images, patterns, or effects.

Zoom in on a printed photograph and its seemingly continuous shades may resolve into thousands of tiny dots—the ingenious trick behind the halftone.

Where does halftone come from?
Halftone developed as a compound of the English words “half” and “tone” during the history of printing and reproductive illustration. Here, “tone” refers to degrees of light and shade rather than specifically to musical pitch. Its “tone” element comes through French from Latin tonus, originally associated with the Greek tonos, while “half” has a native Germanic origin.
