     Having, consisting of, or pertaining to, half tones; specif.

From The Free On-line Dictionary of Computing (27 SEP 03) [foldoc]:

  halftone
       
           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}.
