Glossary of Graphic Arts and Industrial Printing Systems

• Rotogravure — A high-quality printing process or engraving technique (rotogravure / photogravure) in which the printing elements are incised or etched below the surface of a copper plate or cylinder; an artistic or typographic work obtained through this process.
• Autotype — A photomechanical printing process used to reproduce continuous-tone images (photographs, paintings) by means of a screen (halftone screen) that breaks the image down into a dense layout of fine dots of varying sizes. The term also denotes the metallic printing plate (autotype) obtained through this method, historically used for illustration printing in books and newspapers.
• Autotypy — A photomechanical printing process used to reproduce continuous-tone images, such as photographs, by using a halftone screen that breaks tones down into microscopic dots of varying sizes. The term also denotes the metallic printing plate produced via this technique or the final printed image, representing a revolutionary stage in the history of illustrated press.
