D

Descender: in typography, the part of the letterform that dips below the baseline; usually refers to lowercase letters and some punctuation, but some typefaces have uppercase letters with descenders.

Dingbat typeface: a typeface made up of nonalphabetic marker characters, such as arrows, asterisks, encircled numbers.

 

Discretionary hyphen: a hyphen that will occur only if the word appears at the end of a line, not if the word appears in the middle of a line.

 

Display type: large and/or decorative type used for headlines and as graphic elements in display pieces. Common sizes are 14, 18, 24, 30, 36, 48, 60, and 72 point.

Dither: for digital halftones, the creation of a flat bitmap by simply rutning dots off or on. All dots are the same size there are simply more of them in dark areas and fewer of them in light areas -- as opposed to deep bitmaps used in gray-scale images.

DPI (dots per inch): the unit of measurement used to describe the resolution of printed output. The most common desktop laser printers output a 300 dpi. Medium-resolution printers output at 600 dpi. Image setters output at 1270-2540 dpi.

Drop shadow: Drop shadows are those shadows dropping below text or images which gives the illusion of shadows from lighting and gives a 3D effect to the object.

Duotone: a halftone image printed with two colors, one dark and the other light. The same photograph is halftoned twice, using the same screen at two different angles; combining the two improves the detail and contrast.
