The current printing market is a market full of variety, reduction in the number of prints, high requirements on the printing process, and short production cycles. Not being rigidly adhered to traditional printing processes and methods, it is always a constant demand from customers and markets for printing companies. The emergence of multi-function rotary presses has improved the shortcomings of single machine performance, simple process, and fixed print size in the past. It has improved the printing technology of rotary machines to a brand-new field and further satisfied the needs of the market.
Multi-functional rotary printing machine can be used in a variety of printing and post-printing processes, such as plain printing, gravure printing (including gravure printing), flexo printing, screen printing and other printing methods, as well as die cutting, hot stamping, laminating, embossing, Post-press processing such as folding, cutting, and drying, completes the complicated printing processing business with high efficiency.
Using a variety of processes on a printing press is a requirement of the market, and it is also a direction that printing press manufacturers have been striving. Although this kind of technology has already existed for a long time, but because of the technical limitation, cannot increase the unit arbitrarily, has not been the breakthrough development. At present, with the development of non-shaft technology, multi-functional rotary machines have been the basis for the development of multi-functional rotary machines in a variety of printing processes, have greater room for play.
Compared with traditional rotary machines, the characteristics of multifunctional rotary machines reflect the diversification of their functions. The traditional rotary machine has a relatively single function. For example, a flat printing rotary press used in the publishing industry has only a single printing process that can only be printed on paper. The printing size is also relatively fixed, and it cannot adapt to the diversified needs of printing. The multi-functional rotary press is more capable of adapting to the market. According to the needs of the market, different printing processes can be added, different materials can be printed, and the printing length can be changed freely and flexibly.
The emergence of multi-function rotary machines can meet the market's multiple demands for printed materials, and have the following characteristics:
1, a variety of process integration
Each printing process has its own characteristics that are not available in other printing processes. It also has its own weaknesses. At the same time, the market demand also requires that the printing factory can have a variety of printing processes, and use the best combination of techniques to meet the special requirements of different printed materials, avoid weaknesses, and achieve the best printing results. Like Drenthe-Gebbel's press (Drent-Goebel), it is possible to combine the various printing processes and post-press processing units mentioned above and all the processing is done in one go. In addition to the Drenthe-Gebelle company's equipment, the trend of this combination of craftsmanship has become increasingly apparent on other companies' presses. Such as: increase the flexo glazing unit on plain paper printing, increase the screen printing unit on the flexographic printing machine, and add post-press processing equipment on the flexo and gravure web transfer machines.
2, flexible and changeable
The multifunctional rotary machine embodies the concept of on-demand design. According to the business situation, the printing method required by the printing machine can be designed on demand, and a combination of different printing methods can be selected according to their own wishes. For example, a combination of plain and flexo printing can be selected, where the position of the plain and flexo printing units can also be determined as required. In addition, the circumference of the cylinders of the previous rotary machines is irreversible. When printing irregular lengths of business, it will inevitably cause material waste. Multi-functional rotary machines use sleeve technology or plug-in technology, which can easily change the circumference of the printing cylinder to meet the requirements of different sizes of printing products on the printing press.
3, improve efficiency
Gathering its merits in one battle is the best embodiment of efficiency. If a sheet-fed printing press is used for printing with various processes, the production efficiency is low and wasteful. At the same time, there are too many processes, and the placement of semi-finished products will also make it more difficult for enterprises to manage them. The efficiency is very low. The application of multifunctional rotary machines can avoid these problems and meet the requirements of the printing market for high-efficiency production.
4, diversification of printing materials
The diversification of printing materials is also the market's expectation for printing equipment. In addition to printing on plain paper, multi-function rotary machines can also be printed on cardboard, plastic films, aluminized films, self-adhesive stickers and composite materials. For example, Drenthe-Gebelle's equipment solves the problem of printing on plastic films, aluminized films, and composites. Therefore, the company's presses have monopolized the Russian plastic film printing industry. . In the last two months, Russia has purchased 6 Drumt-Gebbel rotation machines.
Drandt-Gebbel is one of the leading manufacturers of multifunctional rotary machines. The company has a history of more than 150 years in producing printing presses, and it is particularly unique in security printing. In the past, currencies of many European countries, such as British pounds, francs, etc., as well as the current euro, have used the company's printing presses. In addition, the stamps of many countries also use the printing presses produced by the company.
At present, the application of multifunctional rotation mainly focuses on several aspects:
1, security printing
Printing of securities, such as currency, stamps, lottery tickets, checks, bonds, etc. Certificate printing, like passports, driver's licenses, various certificates, etc. It is also used in the printing of fragrant packaging, wine labels, and other products with anti-counterfeiting requirements. The use of multi-function rotary machines for security printing is very important for business managers. Because of the multi-functional rotation production, from the time of feeding to the completion of the finished product, the production of defects from beginning to end is recorded and it is easy to manage. The use of sheet-fed printing is different, and the management of unsatisfactory printed sheets from overprinted paper is much more difficult than for rotary printing machines.
This equipment is equipped with line gravure printing, common gravure printing, plain printing, flexo printing, screen printing, rainbow printing, watermark positioning, marking devices in different locations and related post-press processing devices.
2, packaging and printing
Including carton box printing, self-adhesive label printing, sticker printing. Ordinary commercial printing, such as advertising inserts, booklets, etc. This kind of equipment is generally based on plain printing, equipped with flexo printing, screen printing, coating, coating, laminating, bronzing, cutting sheet, die-cutting machine and other equipment. The company's equipment sold to a company in Brazil last year was equipped with 7 sets of plain printing, 4 sets of screen printing, 1 set of flexo and lamination, and other post-press equipment for label printing.
3, flexible packaging printing
Soft packaging printing is printed on plastic films (OPP, PVC), aluminized films, and other composite materials. In the past, gravure and flexo presses were mostly used. However, due to the relatively high plate-making costs of gravure printing and flexo printing, the printing cost of short-run printing plates is relatively high. Dylant-Gebbel's flexible packaging printers use flat-print-based printing, making it possible to print short runs of flexible packaging. However, flexo printing units and gravure printing units can also be provided according to the customer's requirements, so that the flexible packaging printing can be applied to printing and various requirements of the printing. The company's multi-functional rotary press sold to an Austrian company in May was equipped with six sets of plain printing and four sets of gravure printing equipment for flexible packaging printing.
