In photogravure, ink is held in the hollows of a plate rather than on high relief. This method of printing is known as intaglio. The photogravure plate, like the halftone plate, is produced with the aid of a camera and an acid to etch away parts of the metal plate. The acid creates hollows of different depths. The deepest hollows hold the most ink and print the darkest areas in the picture. Shallow hollows hold less ink and print lighter areas.
Dot-matrix printers work by drawing dots in much the same way that typewriters produce characters. They create whole letters by striking a sheet of paper through an inked ribbon. The dot matrix printer is ideally suited for printing carbon-copy forms, but does not find much current use in desktop publishing.
