Short for Lithography. Also called Offset.

A planographic process invented in 1798 by an Austrian Alois Senefelder using the principle of water and oil do not mix. Stone,and later metal plate, was used as the image carrier, in which the image areas and non-image areas were defined chemically. Ink applied selectively to the chemically treated image areas after the non-image areas were dampened with water . Paper then placed on the stone, pressure applied, and the image transferred to the paper. The term, which derives from the Greek words "lithos" meaning "stone "and "graphe" meaning "writing",has now lost its meaning as stone printing except in fine art for making prints. The commercial form of lithography is offset lithography,. However, the term lithography is generally used in the sense of offset lithography and in its shortened form:Litho.

In hand composition,two cases are used to
accommodate a fount of type;one for capital
letters,the other for small letters.On account
of their position on the frame,the case that
holds small letters is in the lower position,
thus called lower case.This term is now
generally used to mean small letters,because
any sorts in the lower case would be small
letters.
