Lithography is a planographic method of printing originally based on the immiscibility of oil and water. The printing is from a stone or a metal plate with a smooth surface. It was invented in 1796 by the German author and actor Alois Senefelder and was initially used mostly for musical scores and maps. Lithography can be used to print text or images onto paper or other suitable material. A lithograph is something printed by lithography, but this term is only used for fine art prints and some other, mostly older, types of printed matter, not for those made by modern commercial lithography.

Gum arabic is a natural gum originally consisting of the hardened sap of two species of the Acacia tree, Senegalia senegal and Vachellia seyal. However, the term "gum arabic" does not actually indicate a particular botanical source. The gum is harvested commercially from wild trees, mostly in Sudan and throughout the Sahel, from Senegal to Somalia. The name "gum Arabic" was used in the Middle East at least as early as the 9th century. Gum arabic first found its way to Europe via Arabic ports, and so retained its name.
