Leader
A leader is a repeating symbol used to draw a reader from one area of an article to another area. Dots are the most common leader elements.
Leading
Leading is the vertical space relationship between one line of type and the next. Computer graphics normally default to +2 points of leading for any given point size selected. (i.e. 10 point type uses 12 points of leading and 14 point type uses 16 points of leading). In general, the larger a point size gets, the better it will look with reduced leading. Increased and decreased leading can also be used for copy fitting purposes.
Line Art
Line art consists of non-shaded or non-screened black and white images. Line art cannot be continuous tone imagery such as photographs or pencil sketches. Some examples of line art are type matter, solid black and white logos, icons or pen-and-ink drawings.
