halftone

The reproducion of {greyscale} {images} using dots

of a single shade but varying size to simulate the different

shades of grey.

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.
