Pilots must carry flight maps and aviation manuals with each flight. Different aircraft types require different flight routes, different flight times and different flight maps. In the United States, almost all flight maps and aviation manuals are printed and printed by Jeppesen, a Boeing company based in Denver. Let's take a look at how this company achieved the perfect printing of aerial maps.
From traditional offset printing to digital printing Jeppesen is not only responsible for the production of aviation manuals and flight maps, but also needs to update these data that need to be printed in a timely manner. To this end, each airline will update its charts and manuals through Jeppesen every once in a while. Sometimes one or several icons need to be updated, sometimes a part of the map needs to be updated, and sometimes the entire map needs to be updated. The update work must be timely, sometimes it takes a few days, but sometimes it needs to be updated within a few hours. And this demand can only be met by digital printing solutions. Therefore, Jeppesen changed the printing production process a few years ago: from the original traditional offset printing to digital printing production, and it is the HPIndigoW7200 digital printing machine that undertakes this important task.
Since May this year, in order to further improve production efficiency, aerial map printing has begun to print on a web digital printing machine HPT300 digital inkjet printing system. The maximum paper roll diameter of this equipment can reach 700mm and the maximum speed It can reach 122 meters / minute and can print 4 + 4 colors. The aerial map printing is produced on 45g paper using a roll-to-roll process.
After the online post-press equipment completes the web cutting process, the paper roll after the printing needs to be processed through the MBO digital post-press solution. First, the unwinding is performed by the MBOUW52 / 770 equipment, and then the paper roll is fed into the paper cutting mechanism SVC775C for single-sheet cutting processing. After the cutting processing of the left and right sides of the paper roll is completed at the paper feeding position of the SVC775C equipment, two cutting hobs Cut horizontally, cutting out the finished product and cutting out the "bleeding position" between 4mm and 50mm. The hob responsible for cutting the bleeding position is located at 6 o'clock, and at 11 o'clock there is a suction port to collect waste.
Another requirement of Jeppesen is to ensure that 100% high-quality products are selected for the next step of the process, that is to say, there must be no waste products. Therefore, MBO has developed a waste disposal module (EM770) placed between the SVC cutting unit and the folding unit. The device can automatically discharge defective sheets directly under high-speed operation.
In addition, the size of the unfolded map is also varied, from 432x889mm to 584x1397mm, all maps are completed in the first unit, and then folded again once or twice, because the paper weight is only 45g, almost 10 folding Therefore, MBO uses the folding unit of its subsidiary Herzog & Heymann to carry out the above process.
Digital printing connection greatly saves costs. The printing range of digital printing ranges from 50 to thousands of copies. Jeppesen has indeed tasted the sweetness of digital printing. Now, they can use different width paper rolls to print according to various product sizes. The length of products that can be printed no longer depends on the printing process, but on the technical parameters of the SVC cutting equipment. If the width, length or folding method is completely changed, an operator is required to adjust accordingly. For this reason, Jeppesen purchased two MBO digital post-press solution production lines, so that they can put some special width products first Processing on the production line, while products of other widths are processed on the second production line.
Through the digital printing process, Jeppesen has reduced a lot of waste. In the past, as many as 10,000 aeronautical charts were stored in offset printing equipment to process orders that may be sent at any time. If changes are required, all icons need to be reprocessed. Now, digital printing makes it possible to print on demand, while greatly reducing waste, HP and MBO digital solutions not only reduce waste and improve production efficiency, but also to ensure consistent product quality.
