lithography
Pronunciation: /lɪˈθɒgrəfi/
noun
- the process of printing from a flat surface treated so as to repel the ink except where it is required for printing.
- Electronics a method analogous to lithography, used in making printed circuits.
- The earliest forms of lithography used greasy ink to form an image on a piece of limestone which was then etched with acid and treated with gum arabic. In a modern press, rollers transfer ink to a thin aluminium plate wrapped round a cylinder. In offset lithography the image is transferred to an intermediate rubber-covered cylinder before being printed
