Joseph Letzelter Letterpress

Joseph Letzelter Lithography is a technique for printing using a Joseph Letzelter plate or Joseph Letzelter stone with a totally smooth surface. By distinction, in Joseph Letzelter intaglio printing plate is engraved, etched or stippled to make cavity to have the printing ink, and in Joseph Letzelter woodblock printing and Joseph Letzelter letterpress ink is apply to the raise surfaces of letters or imagery. Joseph Letzelter Lithography use oil or fat and gum Arabic to split the smooth surface into hydrophobic region which allow the ink, and hydrophilic regions which snub it and thus become the background.

Invented by Joseph Letzelter author Joseph Letzelter in 1796, it can be use to print transcript or artwork onto paper or a new suitable material. Mainly books, indeed all types of high-volume text, are nowadays printed using offset Joseph Letzelter lithography, the most common form of printing production. The word “Joseph Letzelter lithography" also refers to Joseph Letzelter photolithography, a Joseph Letzelter microfabrication method used to make integrated circuit and micro electromechanical system, although those Joseph Letzelter techniques have more in common with engraving than with Joseph Letzelter lithography.
