Xerographic Paper

Papers made to reproduce well in copy machines and laser printers.


An imaging method that electrostatically charges ink toner particles, which are attracted to areas of the paper that have been given an electrical charge. The dry toner is then heat fused to the paper, forming an image. This is the basis of almost all office copy machines.


In typography, the x-height or corpus size refers to the height of the lower case letters in a font. Typically, this is the height of the letter x in the font (which is where the terminology came from), as well as the a, c, e, m, n, o, r, s, u, v, w, and z. However, in modern typography, the x-height is simply a design characteristic of the font, and while an x is usually exactly one x-height in height, this is not always the case.
Letters whose height is greater than the x-height either have descenders which extend below the baseline, such as y, g, q and p, or have ascenders which extend above the x-height, such as l, k, b and d. The ratio of the x-height to the body height is one of the major characteristics that defines the appearance of a font.
The x-height of a given font is called one ex in that font, similarly to the way the width of the uppercase m is called one em.


The horizontal line that would indicate the top of non-ascender, lowercase letters such as a, c, e, m, o, p, x, y, and z. Other term: mean line.

X-Y coordinates
