Screen. In printing. the finely cross-ruled glass plate placed before the lens of a camera (or a contact screen placed in contact with the film) to break up continuous-tone copy into dots for reproduction as halftone or line copy. Screens are designated by number of ruled lines they contain-from 50 lines per inch to 500 lines per inch. The greater the number of lines per inch, the sharper and finer the printed halftone will be. The selection of the screen is dictated by the paper, press, and to a certain extent the nature of the copy. For example, the coarser screens (50 to 55) are used for newspapers, while the finer screens (100-line and up) are used on coated papers.
