halftone

graphics The reproducion of greyscale images using dots

of a single shade but varying size to simulate the different

shades of grey.

Laser printers that cannot print different sized dots,

halftones are produced by varying the numbers of dots in a

given area.

This process is also used to produce a black and white version

of a colour original using shades of grey in place of colours.

See also device independent bitmap.
