From daily necessities to fashion mail-order advertisements, supermarket promotional brochures to magazines and elite newspapers, we are closely related to our daily lives. From the perspective of modern marketing, they effectively promote the communication between merchants and specific target groups. It is an irreplaceable strong media, and only high-quality printing can receive this effect. Commercial web offset presses are a new type of press that meets this printing need.
Commercial web offset presses are a type of web offset press that is a web multicolor offset press capable of printing 175 lines/inch or more of color fine prints. Commercial web offset presses are mainly used for printing color magazines, high-end commercials, high-end promotional materials, pictorials, etc. Due to the increasing volume of high-end magazines and newspapers, the use of sheetfed offset presses has been unable to meet the growing market demand.
Due to the expansion of the market, all famous printing equipment manufacturers have developed their own high-end commercial web offset presses, and have adopted a large number of advanced technologies. For example, Heidelberg's M-600, Manroland's POLYMAN, ROTOMAN, KBA's Compacta818, 215 and other models. The following is an introduction to some of the advanced technologies used in commercial web offset presses, and a rough analysis of the commercial rotary press market.
The latest technology:
No shaft drive technology
The shaftless transmission is an advanced technology. At present, there are two main forms: one is that a printing color group is driven by a servo motor, that is, the transmission shaft is eliminated; the other is that the entire printing unit has no transmission gear and a transmission shaft. Plate cylinders, blanket cylinders, impression cylinders, and inking rollers are all driven by separate motors. The most widely used one is still the first form. Regardless of the form, in order to ensure the accuracy of overprinting, the synchronous performance of each motor is required to be high. It is said that it has reached an accuracy of 130,000th, and only a difference of ±0.01mm in the length of 1.3m.
The advantages of shaftless transmission are mainly manifested in the following aspects: Firstly, the gear transmission is completely eliminated, the oil lubrication is eliminated, and the machine noise is reduced; secondly, the auxiliary time can be reduced. When one unit is printing, another unit can The machine is equipped with a high degree of automation, and the unit combination is simpler and more flexible. The application of shaftless transmission technology makes the machine control of the transmission part highly automated, and the operation is also more convenient and flexible. Each printing cylinder can be operated independently, and it is convenient to assemble and disassemble and clean the blanket and the printing plate. However, the simplification of this mechanical mechanism is replaced by a complicated electrical system, which has a relatively low price relative to the mechanical, stable performance and convenient maintenance.
As far as the actual situation in China is concerned, the mechanical cost is not high, and the electrical price is not low. In comparison, the reliability of the machine and the reliability of the maintenance machine and the convenience of maintenance are more easily accepted by the user, so the current Printing with shaft drives is not a conservative option. However, the market share of shaftless transmission will become larger and larger. From the perspective of development trend, shaftless transmission will replace shaft transmission. At present, the famous shaftless transmission technology providers mainly include: the shaftless drive system of Rexroth Indramat and the shaftless drive system of Lunci. Commercial rotary offset presses that use shaftless drives are mainly models of KBA's Compacta215 and Manroland's POLYMAN.
