Also called middle-tone. (in painting, drawing, graphics, photography, etc.) a value intermediate between light and dark.
a process in which gradation of tone in an image is conveyed by first photographing the image through a screen to break up the continuous tones of the image into minute, closely spaced dots, then using the print obtained to produce a metal plate by photoengraving, and finally using the plate to reproduce the original image by letterpress or offset printing.
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. (1996-09-20)
