write a processing on how to newspaper are published
Answers
Explanation:
The printing process is the main process step during newspaper production. Quickness and reliability with at the same time reasonable producing are the cornerstones in the production and processing of print products.[2] Newspaper presses produce not just goods in process (sheets, signatures or reels of printout) as it is the case with typical printing presses. Instead newspaper rotary presses can produce copies which are finished goods.
The typical newspaper press is divided into two parts: printing and folding.
Printing Edit
The first functions of a newspaper press are loading and unwinding of newsprint reels. These functions are provided by the paster. Pasters unwind paper reels and automatically change paper reels at full production speed (e.g. 100.000 copies per hour). Often pasters are place below the printing towers. The towers often consist of four printing units to print Cyan, Magenta, Yellow and Black ink onto the newsprint. The newsprint web travels upwards in the printing tower during the color is applied to it on both sides of the reel. Usually for every page there is one individual printing plate per color. This printing plate is mounted onto the plate cylinder within the printing unit which again is part of the printing tower. Modern presses can print full color on every page. Four color printing units are used for printing on one side of the paper web and another four printing units apply the backside print onto the paper web. Printing front and backside can happen simultaneously (blanket-to-blanket-configuration) or after another (satellite configuration) The printing units cannot just print one page like in digital printing, instead printing towers in newspaper presses can print up to 24 broadsheet pages in full color. If the press consists of several towers much more pages can be printed at once.
Folding Edit
The folder starts were the printed webs come together. The Folder can produce ribbons and combine these ribbons in such a way that the pages are sorted ontop of each other. The folding process starts in the so called super structure and ends in the main folding units at the end of the press process. The ribbons are cut in such a way that the pages of the newspaper are separated from each other and the folder lays down the newspaper copies onto the delivery belt.
The first real newspaper presses were produced by Koenig & Bauer. The Times in London was printed at first on a rotary/flat machine press instead of a hand press in the night from 28 to 29 November 1819. Today also other manufacturers such as Goss, Manroland Web Systems, TKS, Mitsubishi and TPH are in the press market.
