Mainstream 80 Heidelberg New Newspaper Press

The first large-scale customer survey was conducted in Heidelberg in 1997. Understanding the user’s perception of the 1×4 newspaper press, the customer's response was very strong. More than a hundred managers from the global printing and publishing companies surveyed are clearly aware that single-double-drum double-width rotary newspaper presses have enormous potential economic value and extremely high production flexibility. At that time, no one manufacturer had produced a 1×4 printer; it was able to achieve extremely high production speed without sacrificing print quality. Now, technological advances have successfully eliminated the barriers to productivity growth and made the 1×4 press a reality. Single-trust double-width printing press can realize the output of traditional 16-plate printing; at the same time, it can greatly save the printing plate and provide the layout design flexibility, plus the design of a single trust rubber blanket (the ratio of plate cylinder to blanket cylinder is 1:1). , to make print quality even higher. The perfect combination of output, quality and production flexibility can enable medium and large newspapers to increase their production efficiency, strengthen their competitiveness, and attract more readers and advertisers. 14 Single-edge double-width printing press The most important feature and advantage of the introduction to the target is the saving of printing plates. If you use a conventional double-width 2X4 large-wave street printer, the light-printing plate needs to produce 16 sheets, and the large-scale printing requires copying two sets of the same plate. The lx4 model omits the process of copying plates. It only takes 8 plates to produce. A half plate reduction means savings in plate costs and saving time in plate making and loading. Some newspapers even began to weigh whether to use computer-to-plate technology. The 50% savings will tilt the balance to the new technology side. The use of 1x4 newspaper presses also brings more flexibility to the layout design, and the layout positioning capability will also be strengthened. In the competition with electronic media, these two are the newspapers need to be improved. No need to copy the plates so that newspapers can change the layout more easily to adapt to the constant changes in their content. When changing the layout, the operator does not need to change two plates, change one piece. In addition, in the layout design, the increase in the two editions is more flexible than the increase in the four editions required for the deposit page printing. The newspaper office can modify the editing content or advertisement content more swiftly before the prescribed deadline. The flexibility of layout design can also be enhanced by the non-uniform page number printing function, and newspapers will even increase their revenue accordingly. If individual companies want to spend more money to advertise in the first supplement or other supplemental magazines, the IX4 press will only need to make the desired edition more pages than other editions. The advantage of using a 1×4 printing press for large sets of printing is not only reflected in the printing process. In the post-printing phase, since the folding machine is not used to run pages, the relevant cams can be eliminated, and pinning and synchronous tooth decay can also be fixed. On the wallboard. In print shops, reducing moving parts means that equipment installation and commissioning will be faster. This optimized design will also greatly reduce the workload of equipment maintenance. The above-mentioned advantages of 1x4 obviously will greatly enhance the newspaper's competitiveness and improve work efficiency. However, the newspaper executives who accepted our research in 1997 pointed out frankly that the low yield has always been the shortcoming of this kind of equipment. In fact, most newspaper companies face the same dilemma. 90% or even 100% of the layout is printed in a large format, but in the case of a very large number of editions or publishing holiday numbers, many newspapers occasionally use page savers to save some of the insertion or packaging work. When the page is printed, the printing press can only reach half of the fastest speed, which obviously cannot meet the needs of newspapers to deliver news at the fastest speed. Therefore, high-speed printing with 1:1 rollers is undoubtedly a brand-new challenge. New technologies are just the solution to the problem. One of the reasons that affects the high quality printing of traditional 1x4 newspaper printers is that the dynamic stability of the equipment is not guaranteed. The mechanical vibration generated when the blanket interface meets will cause the narrow single-diameter roller to vibrate, which will directly lead to the quality of the printed product. Eliminating vibration with a single-pass plate cylinder and a double-diameter blanket cylinder (2:1 ratio) is a viable option, but this sacrifices the excellent quality that can be achieved with a 1:1 ratio. It turns out that the seamless roller is the best way to solve the problem of the vibration of the sleepy blanket. Using this technology, the double-web newspaper press can be produced at a high speed of 80,000 rpm under a 1:1 ratio of a single-diameter plate cylinder and a single-diameter blanket cylinder while ensuring excellent print quality. In 1992, Heidelberg introduced a press that uses seamless "Sunday" technology, setting off a revolution in the field of rotary printing. Most importantly, seamless blanket cylinders featuring vibration reduction allow commercial printers to print faster - up to 100,000 rpm for wide web presses. Heidelberg's “Mainstream 80” seamless 1×4 newspaper press is bringing the success of the commercial printing sector to the newspaper printing sector, bringing higher productivity, productivity and print quality to newspaper printing companies.
