Title: Screen for halftone photography
Inventor: MASUDA TOSHIAKI
IPC: G03F5/02
Filed: 1980-04-11
Abstract: PURPOSE:To prevent moire  and avoid roughness and unevenness by irregularly changing the shape and size of the transparent parts of a glass screen for halftone photography consisting of transparent and opaque parts. CONSTITUTION:An opaque part consisting of many irregularly bent segments 3 of lines and polygonal transparent parts 4 enclosed by segments 3 are formed on a glass substrate so that the area of parts 4 is adjusted to 16-25% of the total area. Since parts 4 are different from each other in area and shape, moire  is not caused even if a plurality of such glass substrates are superposed in multicolor printing. In addition, parts 4 are specified in size and shape, so a glass screen having sufficient tone reproducibility and causing no roughness and unevenness to an image is obtd.
