During the Chinaprint2013 exhibition, at the booth of Shanghai Electric Printing and Packaging Machinery Group, a grand new product launch was held. For the first time, an offset printing machine that combined digital printing with traditional offset printing technology-the Gauss Magnum Compact printing machine was launched. This is the world's first highly automated compact 2 * 1 newspaper, book and semi-commercial rotary offset press, breaking the limitations of traditional rotary offset presses, and having the ability to challenge inkjet digital printing.

At the information sharing meeting of Chinaprint 2013 held on July 11, Zhang Yingxing, assistant general manager of the global rotary offset printing giant Gauss International Graphic Printing System (China) Co., Ltd. sales company, introduced Magnum Compact's innovative web offset press . Zhang Yingxing said: Today, the Internet, new media and digital printing have already had a big impact on the traditional industry, and the paper media is the first to bear the brunt. The wave of digitization is sweeping the world. The digital revolution has brought progress to the world while making many traditional industries at risk. As a manufacturer of traditional printing equipment, we can't wait and die, we must follow the trend, actively innovate and change, and stand on the tide without falling. The new generation of web offset press Magnum Compact designed by Gaussian with innovative ideas is the result of Gauss' active change.

In the speech, Zhang Yingxing highlighted four major technical highlights of Magnum Compact's new web offset press:

One. Printing tower height is greatly reduced

The vast majority of newspapers and some books and magazines in the world are printed on a tower machine, which is characterized by fast speed and high efficiency, but there is also a problem that the height is more than 4.5 meters, plus the above paper roller , Up to 4.7 meters or more, therefore, in addition to the necessary height requirements for the plant, workers have high work intensity and high maintenance requirements. The Gauss Magnum Compact has made major innovations in design ideas, that is, greatly reduced the height of the machine, reduced the height of the printing tower to less than 2.8 meters, and changed the two-layer operation into a one-layer operation, completely solving the height of the plant that may be encountered Problems and the inconvenience of workers.

The traditional printing part is that the printing cylinder and the waterway ink system are all on one wallboard, and the new design of Gaussian divides the wallboard into three. The middle wallboard is installed with a printing cylinder and a water delivery system, and the symmetrical wallboards are installed Inking system, so that the entire height is greatly compressed. The latest surprise is that the ink wall panels on both sides can be opened smoothly, allowing the operator to easily enter the inside to replace the rubber roller, disassemble the rubber blanket and other necessary maintenance work. Another feature is that the ink channels on both sides are suitable for printing cylinders of different diameters. If you need to print products of different specifications, you only need to replace the middle part, and the ink channels on both sides can be used universally.

two. Automatic plate changing device

In today's era of increasing human resource costs, how to improve the automation of equipment and reduce the use of labor has become the most entangled problem for corporate leaders. Magnum Compact adopts the automatic plate-changing design. Just put the new plate in the plate-installing mechanism and press the button to remove the old plate and automatically install the new plate. The eight plates in one tower are replaced at the same time. In less than 30 seconds, you can really do it with one click. The removed old version will not be damaged at all, and can be used continuously. "If you use traditional manual work, it will take about 10 minutes for two people to install the plate at the same time, and the plate opening of the unloaded plate is basically damaged and can no longer be used. The application of this automatic plate change device not only reduces the number of crew members It also greatly reduces the pre-press preparation time and the loss of materials. This automatic plate-changing mechanism seems simple, but it is actually very cleverly designed. "Zhang Yingxing compared the effect of automatic plate-changing with traditional manual operations.

three. Gaussian DigiRail digital ink fountain

The Gauss DigiRail digital ink fountain is actually a set of digitally controlled inkjet device installed in the original ink fountain. The system consists of 4 inkjet pumps. Since the ink supply is completely digitally controlled according to the actual needs of the layout, there is no unnecessary waste, and cleaning is also very convenient. The inks and plate materials used as well as paper are the most commonly used materials for offset printing, and will not add any additional cost to the enterprise. Its biggest advantage is that, while maintaining the printing advantages of traditional rotary offset printing, it can print as few as 500 copies of short-page business, thus providing more flexibility and opportunities for printing companies to undertake business. It is comparable to digital printing in scope.

four. Shaftless drive control system

The drive of Magnum Compact machine adopts shaftless drive control. Each printing tower is equipped with 7 shaftless motors to control each part separately. The printing part consists of 4 sets, which mainly control the operation of the printing cylinder; the ink system has 2 sets, which control the operation of the ink rollers; the paper feed section has 1 set , Mainly adjust the tension of the paper path, plus the advanced control system of automatic presetting and starting sequence, making the whole machine more accessible and more flexible in operation.
