Abstract

The screen is formed by a sheet, preferably a film,comprising a system of opaque and transparent, substantially square-shaped dots in chess board arrangement. In each opaque dot is a substantially centrally situated transparent circle occupying substantially 5% of the area of the associated square-shaped dot. The screen is prepared photographically. <IMAGE>

Description

Vynález se týká kontaktně] kombinované] autotypickej siete — rastru, u ktorého sa rieši štruktúra tlačového bodu к rozkladu čiernobielych a farebných obrazov na jednotlivé tlačové prvky. Kontaktná kombinovaná autotypická sieť — raster sa používá při výrobě reprodukci! v polygrafickom priemysle pri tlačí ofsetom, čo představuje tlač z plochy a kníhtlačou, teda tlačou z výšky, pričom spojením jednotlivých tlačových prvkov vzniká obraz. Doteraz známe druhy autotypických sietí — rastrov pracujú s tlačovými prvkami tvaru elipsovitého, kruhového, najčastejšie čtvercového. Su vyrábané tiež speciálně autotypické siete — rastre zrnité, linkové, vytvárajúce rožne vzorce a struktury, imitácie textilu a podobné. Autotypické siete — rastre rozdělujeme na negativné a pozitivně a podlá počta bodov na 1 cm na 25, 40, 48, 54, 60, 70, 80 linkové a hustejšie. Novšie sa vyrábajú autotypické siete — rastre zdvojené z bodov rózných velkostí vedla seba, čím sa dosiahne zlepšeme pri přenose čo najváčšieho počtu informaci! z originálu do reprodukcie. Najpoužívanejšie su autotypické siete — rastre klasické so štvorcovými tlačovými prvkami usporiadanými v podobě šachovnice. U uvádzaných autotyplckých sletí - rastrov má tlačový prvek najkrytejšio jádro a smcrom к okrajom hustota krytu ubeda. Při použití vyššie uvádzaných autotypických sietí — rastrov popři kresbe vystupuje tvar tlačového bodu. Při požiadavke zvýraznenia podrobností alebo detailu sa musia používal autotypické siete — rastre hustejšie než 54 bodov na 1 cm, čo si vyžaduje potřebu kvalitného hladeného povrchu tlačového papiera a ďalšou nevýhodou je možnost zanášania farby. Při použití autotypickej siete — rastru hustejšieho než 60 bodov na 1 cm; klesá kontrast a tlač je náročná.The invention relates to a contact combined autotypic grid, in which a print point structure is solved to decompose black and white and color images into individual printing elements. Contact combined autotypic network - raster is used in reproduction production! in the printing industry by offset printing, which represents printing from the surface and letterpress, that is, printing from a height, whereby joining the individual printing elements creates an image. Previously known types of autotypic networks - raster work with printing elements in the shape of elliptical, circular, most often square. Especially autotypic nets are also produced - grainy, line, creating various patterns and structures, imitation textiles and the like. Autotypic nets - rasters are divided into negative and positive and according to the number of points per 1 cm to 25, 40, 48, 54, 60, 70, 80 line and denser. More recently, autotypic nets are produced - streaks doubled from points of different sizes next to each other, thus improving the transmission of as much information as possible! from original to reproduction. The most commonly used are autotypic nets - classic rasters with square printing elements arranged in the form of a chessboard. In the mentioned auto-mastic raster-raster, the printing element has the outermost core and facing the edges the density of the cover less. When using the above-mentioned autotypic networks - raster along with the drawing, the shape of the print point arises. When detail or detail is to be emphasized, autotypic meshes must be used - denser than 54 dots per cm, requiring a high-quality, smooth surface of the printing paper, and a further drawback is the possibility of clogging. When using an autotypic grid of a density of more than 60 dots per cm; contrast decreases and printing is difficult.

Uvádzané nevýhody používaných autotypických sietí —- rastrov zmierňuje kontaktná kombinovaná autotypická sieť — raster, ktorého podstatou je liárok obsahujúci systém nepriehladných a transparentných v podstatě štvorcových bodov v šachovnicovom usporiadaní, kde v každom nepriehladnom bode je v střede umiestnený priehladný kruhový bod zaberajuci 5—9 '% plochy příslušného bodu.The aforementioned disadvantages of the used autotypic networks are reduced by the contact combined autotypic network - the raster, which is based on a collar comprising a system of opaque and transparent substantially square points in a checkerboard arrangement, with a transparent circle point occupying a center at each opaque point. % of the area of the point.

Na obrázku je znázorněný tvar bodu štvorcovej autotypickej siete — rastru A v porovnaní s tvarom komkinovanej autotypickej siete — rastru B. Předloha G znázorňuje rozhranie svetlej a. tmavěj plochy. Pri použití autotypickej siete — rastru D dostaneme reprodukcím E. Ak předlohu F, ktorá znázorňuje zohranie svetlej a tmavěj plochy rozložíme pomocou kombinovanej autotypickej siete — rastru fí, výsledkom je reprodukcia H.The figure shows the shape of the point of the square autotypic grid - raster A compared to the shape of the com- bined autotypic grid - raster B. The template G shows the interface of the light a. darker areas. When using an autotypic network - raster D we get reproductions of E. If we decompose the template F, which shows the playing of light and dark areas using a combined autotypic network - raster phi, the result is reproduction H.

Kontaktná kombinovaná autotypická siet — raster zvýrazní ostrost tlačových bodov a reprodukované obrazy sú dokonalejšie, s vyššou obrysovou ostros ou a lepšou kresbou..

PoužiteToosť kontakíuej kouť movfmej autotypickej slete — rastru je všeobecná v grafických technikách v ofsete a kníhtlači. Zvlášť jo výhodné pouužitie pře elektronické scanery. Efektne působí tlačový bod zvačšený v gigantografii ako například u reklám, plagátov a podobné. Použitím kontaktnej kombinovanej autotypickej siete — rastru sa zlepší kvalita obrázkov novin a časopisov, ktoré sú tlačené ofsetovou rotačnou technikou.Contact combined autotypic network - raster enhances sharpness of print dots and reproduced images are better, with higher contour sharpness and better drawing ..

The use of the contact corner of a moveable autotypical skeleton - the raster is generic in offset and letterpress graphics techniques. Especially advantageous use over electronic scanners. A gigantic press point, such as ads, posters, and the like, works well. The use of a contact combined autotypic grid - raster improves the quality of pictures of newspapers and magazines that are printed by offset rotary technology.
