What future does drupa point to for offset printing equipment

the drupa exhibition, which has attracted the attention of the industry, has been held in Dusseldorf, Germany. At this exhibition, the technical focus will be on providing solutions to the problems faced by today's printers. Maximizing production efficiency, providing value-added services, multiple choices of printing machine format, and reducing the impact of printing on the environment will become the four predictable development directions of offset printing equipment

for more than 50 years, printers have always gathered in drupa to see the latest development of printing machine technology. The spring of 2008 is no exception. At that time, global printers will go to Dusseldorf to witness the technological progress demonstrated by the five major sheet fed printer manufacturers of Heidelberg, Manroland, gaobao, Komori and Mitsubishi. At the previous drupa exhibition, equipment manufacturers competed to show technological progress to attract the attention of the audience; At this exhibition, the technical focus will be on providing solutions to the problems faced by today's printers

this will mean the emphasis on efficiency, which is manifested in improving the connection and reducing the printing preparation time; For the improvement of the versatility and productivity of the printing machine, the former can increase glazing and other wire processing processes, while the latter can show faster printing speed and larger paper size. On the whole, the automation function of the printing press will be strengthened, thus reducing the requirements of the equipment operation on the personnel level.

as printing is undergoing essential changes, all these are necessary. Print must justify its superiority over other media, and printers have to deal with very professional buyers who plan to purchase globally. Speaking of drupa, Bernhard Schreier, CEO of Heidelberg, pointed out that the competition for time insensitive products has spread all over the world, which means that printers in developed countries have to change themselves in order to compete. He explained as follows: only when printing service providers systematically develop from handicraft to industrialized technology can they maintain long-term competitiveness and profits. Printing enterprises must be equipped with the latest printing machines and systematically integrate and link all processes

Albrecht Bolza Sch nemann, President of drupa and CEO of gaobao company, agreed. Looking forward to the drupa exhibition in 2008, he said: what you can expect is the higher performance of the digital printing system, all the workflow solutions covering the whole printing production process, as well as the development of automation and integration process (wire surface finishing, wire quality control, etc.) of the mysterious protagonist conventional sheet fed and web printing machines in this exhibition

at the previous drupa exhibitions, the potential benefits obtained through CIP3 and JDF have been discussed. At this exhibition, as each equipment manufacturer has experience in test installation and has real data to prove that this is a more productive and effective way of working, this potential will become a reality. The data gap is being filled with the expansion of JDF impact. Now the prepress information used to set the ink fountain is being connected through the paper specification and grade setting information provided by the paper mill and the paper merchant

if the machine functions well, it can maximize the production efficiency.

attention to Heidelberg will be divided into two parts: one is its new large format printing machine series, and the other is aniclor ink supply system. Both are responses to changing circumstances that printers find themselves having to cope with. The release of the large format xuba xl145 and XL162 sheet fed printers will become the focus of attention. Based on the successful 18000 sheet/hour design of xuba xl105, they will wait for their first sailing at the exhibition. Compared with the 40 inch (B1 format) printer, the larger format equipment enables commercial printers to place more pages, labels, carton unfolding planes or mixed products on a piece of paper. The development in the fields of large edition software, computer direct plate making and automatic setting means that it is as easy to operate these devices as to operate full open or folio printing presses. Heidelberg has discussed to provide double-sided printing options for these devices. If the double-sided option is indeed added to the xuba xl105, a larger format printer may be introduced as a printer with full page glazing and UV performance options

like Roland, gaobao has the most experience in the large format field. It will emphasize the value of the wide width double-sided printing machine for the 40 inch double-sided printing machine. Japanese equipment manufacturers continue to consider whether the size of the market enables them to provide a larger format, rather than focusing on reducing the printing preparation time and improving the automation of their existing equipment. Mr. Neil Sutton, general manager of Komori UK, said: we are all in a very competitive world. As it is extremely difficult to face low-cost competition, maximizing production efficiency is all part of the market competition. Komori is already a pioneer in automation. We are constantly improving the automation level of equipment. I am sure this will be obvious at the drupa exhibition in 2008

for Roland and noble, the next step is to place a separate motor on the plate cylinder so that the plate cylinder can run independently, so that the setting process can be started in parallel. This means that all plates can be replaced in several steps at the same time, such as cleaning the blanket and replacing the plates can be carried out at the same time rather than in sequence. Dr. Markus Rall, director of Manroland sheet fed printer, believes that since the DirectDrive, the time of plate replacement has become irrelevant. He said: by making processes such as cleaning the blanket and pre inking happen in parallel, we can shorten the printing preparation time. Taking a minute to change a printing plate is no longer a relevant factor. DirectDrive gives us the highest productivity we need to process short print

get value through additional services

dr. Markus Rall added: since all printers have demanding customers, they need shorter printing preparation time, that is, they must produce live parts according to quality requirements at a lower cost. Printers must also be more than just printing companies. They must become service providers to make themselves different

the requirement to become a service provider emerged with another key theme of drupa: value-added printing. For printers who must provide the fastest delivery turnover of short version live parts, the automation function provided by Roland DirectDrive, Mitsubishi simulchange and gaobao drivetronic will be indispensable. For other printers, what is needed is to add additional colors, coatings and gloss to provide more choices to print buyers as a means to create differences between the two printers. In addition, where possible, different production steps must be carried out simultaneously with the printing process. This demand is leading to printers equipped with more than one coating unit and combined dryers, and to be able to print on a wider range of materials. The wire stamping function is increasingly becoming an option that can add more value to the printing sheet. Glue is applied to the paper on one printing unit, and then metal foil is laminated on the next unit, and the metal foil is bonded to the glued image. If the metal foil is too large, metal ink will be printed to produce different effects, which will increase offset printing. This method is now more and more popular

other wiring options include embossing and die cutting, which can eliminate the post production process. For large format printers, the paper cutter in the paper receiving device will cut two live parts in parallel, or generate a large sheet that is easier to finish. Similarly, printing UV ink is becoming more and more popular. UV ink has a higher level of gloss, and the paper collected at the paper receiving device of the printing machine is completely dry and can be processed immediately after printing. UV offset printing is expected to achieve an annual growth rate of 10%

uv printing also extends the range of inks and coatings that can be used. An interesting area where gaobao will make great efforts is to enhance the integration between printing machines and RFID tags on paper, so as to further move towards computer integrated manufacturing. At the same time, RFID tags themselves are another application place open to UV sheet fed offset printing technology. Mr. Klaus Schmidt of gaobao explained that this method integrates the off-line process into the printing machine in order to shorten the production cycle. Recent developments include the placement of a corona discharge type electrostatic eliminator in front of the printing unit to improve the adhesion of the ink to the substrate so that it can be printed on plastic

this level of continuous production is a need to ensure quality. With Manroland, gaobao and Mitsubishi's leading technology in the packaging field becoming the mainstream, the detection system will be widely used. Video detection can detect every piece of defective paper and reject those that do not meet the set standards. Heidelberg adopted a different method. It installed a spectrophotometer inside the printing press, which can measure the color of each paper. For the speedpa CD74 printer, this method shortens the printing preparation time and eliminates the quality fluctuation in one batch printing. Other equipment manufacturers provide this closed-loop control through the console

more choices of format and paper size

gaobao company is climbing to the commanding height of large format printing machine, from rapida 1 with a high integration of 30 to rapida 205, which is almost undoubtedly the world's largest format sheet fed printing machine. At the drupa exhibition, gaobao will demonstrate the double-sided printing technology on these printing machines, emphasizing the great productivity of double-sided printing in one pass. 16 or 32 pages can be arranged on a piece of paper. Gaobao's technology will arouse great interest of book and periodical printers, but digital printing still has a significant impact on these printing enterprises

small printing enterprises will get interesting choices for the size of printing machines. Equipment manufacturers such as Sakurai and lyubi began to enter the field of large format printing presses because digital equipment manufacturers invaded their traditional market territory. However, they are not in close contact with the five major equipment manufacturers, but the equipment that produces printable sra1 (36 inch) paper. These manufacturers believe that the extra paper size is superfluous for many printing enterprises. A 92cm wide device means that printing enterprises can print paper that can fit 8 pages without spending too much money

small printers around the world are indeed faced with the choice of embracing digital printing or maintaining offset printing. The direct imaging equipment of pressek and screen company has brought an interesting intermediate point. In particular, pressek is planning to display a direct imaging equipment that can be arranged for four pages. More printers will be attracted by Heidelberg's Anicolor ink supply system. Since this concept has been recognized by many printing enterprises, it is speculated that large format equipment will be added to the 52cm wide list in the drupa exhibition. In Anicolor ink supply system, the conventional 18 ink rollers queue is replaced by two ink rollers with the same size as the plate cylinder. In each rotation, the plate is applied by the embossing roller instead of the ink key
