Analysis on the advantages of multi-functional rotary machine

the current printing market is a market with the characteristics of diverse varieties, reduced printing number, high requirements for printing process, short production cycle, etc. it is not confined to the traditional printing process and methods, but changes with the requirements of customers and the market. The emergence of multi-functional rotary printing machine has made up for the defects of the previous rotary machine, such as single performance, simple process, fixed printing size, etc., raised the printing technology of the rotary machine to a new height, and further met the needs of the market

the multi-functional rotary machine can integrate a variety of printing and post press processes, such as offset printing, gravure printing (including line gravure printing), flexo printing, printing and other printing methods, as well as post press processing processes such as die cutting, bronzing, laminating, embossing, folding, cutting and drying, and can efficiently complete complex printing and processing businesses

using multiple processes on one printing machine is the demand of the market and the direction of the printing machine manufacturers. Although this technology has existed for a long time, due to technical limitations, the units cannot be added arbitrarily, so there has been no breakthrough. At present, with the development of shaftless technology and sleeve technology, it has a foundation for development and has more room to play in integrating a variety of printing processes

compared with the traditional rotary machine, the multi-functional rotary machine is characterized by its diversified functions. The traditional rotary machine has a single function, such as the offset rotary machine used in the publishing industry. There is only one printing process, offset printing, which can only be printed on paper. The printing size is also relatively fixed, which can not meet the requirements of printing diversification. The multi-functional rotary machine has a strong ability to adapt to the market. It can increase different printing processes according to the market demand, and can print different materials. The printing size is also relatively flexible

the emergence of the multi-functional rotary machine can meet the various needs of the market for printed matter, and has the following characteristics:

integration of various processes. Each printing process has its own characteristics and weaknesses that other printing processes do not have. At the same time, the market demand requires the printing factory to have various printing processes. According to the special requirements of different printing materials, the best process combination is used to develop strengths and circumvent weaknesses, so as to achieve the best printing effect

flexible. The multi-functional rotary machine embodies the concept of on-demand design. The printing methods required by the printing machine can be designed according to the business conditions, and the combination of different printing methods can be selected according to their own wishes. For example, you can choose the combination of offset printing and flexo printing, and the location of offset printing and flexo printing units can also be determined on demand. In addition, in the past, the circumference of the drum of the rotary machine was unchangeable, which inevitably caused a waste of materials when printing businesses with irregular sizes. The multi-functional rotary machine uses sleeve technology or plug-in technology, which can change the circumference of the printing cylinder to meet the requirements of different sizes of prints on the printing machine

improve efficiency. It is the best embodiment of efficiency to finish one service. If the sheet fed printing machine is used for printing of various processes, the production efficiency is low and the waste is much. At the same time, too many processes and the placement of semi-finished products will also increase the difficulty of enterprise management and reduce efficiency. The multi-functional rotary machine can avoid these problems and meet the requirements of the printing market for high-efficiency production

diversified printing materials. The diversification of printing materials is also the expectation of the market for printing equipment. In addition to printing on ordinary paper, the multi-functional rotary machine can also print on paper jam, plastic film, aluminized film, self-adhesive and composite materials, which can also be used by computers for various functions, data processing and analysis, and experimental results printing. For example, Drent Goebel's equipment solves the problem of offset printing on plastic film, aluminized film and composite materials. Therefore, the company's printing machine occupies a monopoly position in the plastic film printing industry in Russia

at present, the application of multi-functional rotary machine is mainly concentrated in three areas:

1 Secure printing. Printing of securities, such as money, stamps, lottery tickets, cheques, bonds, etc; Certificate printing, such as passport, driver's license, various certificates, etc; It is also applied to cigarette packaging. People can accurately and approximately imitate the external environmental conditions that engineering products bear in the process of use, storage, transportation, etc. wine labels and other products with anti-counterfeiting needs can be printed. It is very important for enterprise managers to use multi-functional rotary machine for safe printing. Because the production with the multi-functional rotary machine can be completed at one time from the paper feeding to the finished product, and the production process is recorded from beginning to end, which is easy to manage. The use of sheet fed printing is different. It is much more difficult to manage the printing sheets from the master paper to the unqualified printing sheets than the rotary machine

2. Packaging printing. Including carton packaging box printing, laminated label printing, self-adhesive label printing, etc., and ordinary commercial printing, such as advertising inserts, brochures, etc. This kind of equipment is generally based on offset printing, equipped with online equipment such as flexo printing, printing, glazing, gluing, film covering, bronzing, sheet cutting, die cutting, etc

3. Flexible packaging printing. Flexible packaging printing refers to printing on plastic film (OPP, PVC), aluminized film and other composite materials. In the past, gravure printing and flexographic printing machines were mostly used. However, due to the high plate making cost of gravure printing and flexo printing, the printing cost of short plate printing is relatively high. The flexible packaging printing machine of delant Gerber company uses offset printing, which makes it possible to print short version flexible packaging prints. However, flexographic printing unit and gravure printing unit can also be equipped according to the requirements of customers, so that flexible packaging printing can be suitable for various printing volumes and printing pieces with various requirements. The multi-functional rotary machine sold by the company to an Austrian enterprise in May is equipped with 6 groups of offset printing and 4 groups of gravure printing equipment for flexible packaging printing

jdf is the abbreviation of job definition format. JDF is not a product, but a data format. Initiated and developed by Adobe, Agfa, Heidelberg and MAN Roland, it plays an important role in digital workflow. JDF is aimed at all printing fields, including e-commerce in the printing industry and information management system in the printing industry. JDF has become one of the core contents of CIP4 standard with raster on projection screen, and is under the control of CIP4 organization

The two design objectives of JDF include:

first, it is used for information exchange between different applications or systems serving a complete printing job

second, it is oriented to the whole graphic field, including consumables, design, graphic creativity, on-demand printing and e-commerce for various processes

jdf is a data exchange format based on XML. It has the advantage of XML format - scalability. Therefore, JDF is highly extensible and can meet new requirements in the future. JDF can be flexibly adjusted according to the process of each user

since JDF is a manufacturer independent standard, it is helpful for manufacturers to develop their own related applications. It provides users with a comprehensive and flexible solution, which can connect isolated systems in printing work to serve complete user jobs

American scientists have long been committed to the study of a protein molecule called bacteriorhodopsin: illuminating its protein can trigger a photochemical reaction circle. The principle is that the photochemical reaction circle transports protons along the channel surrounding the cell membrane. The purplish color of this cell membrane is derived from the bacteriorhodopsin component known as the "optic membrane". The amino acids in the cell membrane channels are firmly bound to the "optic membrane". However, the "optic film" in the dissolved state does not combine with amino acid and is pale yellow

by alternately irradiating the protein molecule with two groups of lasers with different wavelengths, the protein molecule can be converted between purple structure and yellow structure. It is this habit that inspires people to study and use bacteriorhodopsin. The bacteriorhodopsin film can also change its color according to the conversion of external electric field. In the conventional bacteriorhodopsin, a low contrast color change from purple to blue will be formed under the action of different electric fields. However, the bacteriorhodopsin structure produced by a certain mutant will change from blue to light yellow under the action of strong electric field. A display plate can be made by clamping the protein film in a transparent plate with a large number of electrodes. Applying appropriate voltage to different parts of the film can "write" a page of manuscripts or "place" an image on the display panel

like the ink on paper, the image on bacteriorhodopsin display plate can be seen under ordinary light, and the protein film also provides the advantage of high contrast
