Line art and text require very clear edges and high contrast between areas where there is ink, and where there is not. However, photographs and drawings usually require varying degrees of ink density for accurate representation. A film that provides this variable density output is referred to as a halftone.
A series of dots arranged in a specific pattern. Also known as a grayscale bitmap, halftones are popular for the laser engraving of photographs.
Gradations of tone in one color that give the effect of shading.
A technique of representing shadings by dots produced by photographing the image behind a fine screen
Dot system of color photo’s to black and white.
Also known as "grayscale." Refers to reproduction of shades of gray.

Halftones are the graduations of tone in painting and drawing which separate the strongest lights from the deepest shadows. They soften the transition from lights to darks, creating an authentic illusion of relief on forms.
A photomechanical process that converts continuous tone illustrations or photographic images into a dot formation for reproduction by printing.
The reproduction of continuous-tone artwork, such as a photograph, through a contact screen, which converts the image into dots of various sizes
