dither pattern or dithering:  An image processing technique that creates the visual illusion of continuous tones when an image is printed.  The illusion of shading is obtained by the calculated placement of picture elements that usually can not be resolved by the human eye.  The calculated placement of the picture elements is called the dither pattern and creates more colors and shades of color than would be printed otherwise on printers with fixed intensity, fixed size printels.
