Large format roll paper printer

The 64-page roller offset press can print both long-run and short-run prints. It can not only print a large number of products but also can print fewer pages, conforming to the development trend of multi-function and high-volume production. Earlier this year, an Austrian printing company called Tusch-Druck GmbH started a 64-page web offset press worldwide. This printer can print long-lived prints that were originally printed in photogravure, and print short-lived prints of new, professional publications. This four-unit, single-sheet, paper-fed printer runs at 40,000 rpm. The roller can accommodate 4 sheets of standard-size paper at one time in the circumferential direction, and can accommodate 8 sheets of standard-size paper at a time in the axial direction (64 pages can be printed in the double-side printing mode). Mann Rolland is the designer and manufacturer of Lithoman IV, also known as a large format offset press. The scope of Tusch-Druck's business matches exactly with the capabilities of the press: - Longer pages with more pages (product catalogs and general magazines, etc.) - Less pages with longer pages (supplies, manuals, etc.) - - Shorter pages of more pages (product catalogues for special groups, professional magazines, etc.) 1 million or 50,000 copies Tusch-Druck is Austria's largest commercial printing and publishing printer. It uses this press to produce four-color catalogs and magazines with a volume of more than 1 million copies, and it can also be used to produce products with as little as 50,000 copies. The company, which was founded in 1958 and currently has 350 employees, has grown into one of the largest printing companies in Europe, with an annual turnover of approximately $75 million. Anton Tusch, one of the company’s founders, said that in 1997, one of their gravure workshops suffered about half of their assets due to fire. At that time, they faced a choice: whether to reinvest in gravure printing, or to completely renovate the printing shop, so that the company could achieve the same high productivity as gravure printing, while still taking full advantage of the versatility of web offset presses. , improve the boot speed and adapt to the requirements of short-run printing. The company has started the 48-page Lithoman IV press since August 1998, but it has not given up on its continued search for larger format presses. Anto Tusc had the initial idea of ​​a 64-page press in a conversation with the head of the press operation of Mann Rowland. Tusch-Druck has been looking for a high-yield printing press, hoping that it does not require as long a plate-making time as the gravure printing press, and the printing rate is no less than 200,000 copies. They think that the 64-page Lithoman IV press can meet these requirements. At the end of 1999, they eliminated the last gravure equipment. Producers and Consumers Tusch-Druck produces advertising products, popular culture books, encyclopedias, television magazines, and catalogues of works of art for publishers, trading companies, and advertising companies throughout Europe. The company is located in Neudorfl near Vienna, but they deliver goods to customers in Istanbul, Hamburg, Paris and Moscow every day. The company prints an average of 2,339 readers a day for 238 million readers and consumes more than 300 tons of paper. This printer can print almost all kinds of format products, and its print capacity accounts for more than a quarter of the company's total. Since its establishment 40 years ago, the company has been striving to carry out technological innovations to bring benefits to its customers, and is therefore always in a favorable position in market competition. Four years ago, they introduced the Sunday Technology in Heidelberg. At the time, that was a very correct choice. Now, they are working with Mann Rolland for another innovation. At present, they have the capability to produce long-run, short-run, multi-page, and fewer-page jobs. The company now needs printer technology that can adapt to the trends in publishing and printing. The 64-page print will be the new standard for publishing and printing. When using a 64-page web press, only a single set-up can be used to print multiple copies (for example, 40,000 copies) of 64-page prints without having to print as many times as before, wasting a lot of boot preparation time. For Tusch-Druck, this is a fast track. The company also has a complete prepress facility that can handle up to 250 color images per day. The company has two Man Roland web presses (a 64-page Lithoman IV and an 84-page Lithoman) and four Heidelberg web presses (a M-3000 purchased in 1996. The Sunday press, a 24-page M-2500, a 32-page 850B, and a Web16). They also have a PrintRoll system, five Muller Martini saddle stitchers and a 20-unit Muller Martini perfect binder. Mann Rolland said that the change trend of printed publications is that the print volume is getting smaller and smaller, job replacement is more and more frequent, print volume is separated, the printing stage is fast, special format and folding forms are used, and page breaks are flexible. Man Roland wants to seize this opportunity to improve the Lithoman IV press to a 64-page high-production model. But also to make it more functional, including boot speed, reduce waste, simple operation, high printing rate and high production quality. Size increase The 64-page Lithoman model is based on the 48-page Lithoman model, which adds 16 pages to the 48-page model. Therefore, increasing the size of the Lithoman roller to 64 pages requires solving many technical problems, including product transfer parameters, temperature-controlled ink supply and dampening systems, plate locking and plate processing, roll cutting, and lengthened Drying equipment and so on. Mann Rolland technicians have adopted a large number of electronic control methods in product design and press pre-setting to achieve the goal of shorter press release periods and quicker job replacement. For example, in the case where two operators are operating at the same time and Man Rolland Power Plate Loading is fully automated, it is possible to complete the change in 12 minutes without moving the roll. In addition, the model is equipped with automatic blanket cleaning system, automatic ink supply mechanism, high-tech register control, and fully automatic convertible folding roller folding device.
