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.
