Talking about: the popularization and application of intelligent post press processing

computer and luoqian high and new technology in the field of printing has enabled the printing industry to embark on the road of 7 intelligent and integrated production from prepress graphic production, plate making and management to digital and networked printing and automatic post press processing, so as to make the quality, speed and form more meet people's needs. Intelligent printing has changed various defects of traditional printing, improved the quality of printing products, and opened up a way forward for the rapid development of printing industry. Now, with the gradual popularization of intelligent printing in prepress and printing, it has begun to land and rapidly expand in post press processing, making the post press processing of bottle pre printing industry gradually embark on the implementation of high and new technology, It can be predicted that intelligent printing drama will be the main direction of printing development in the future

the development of science and technology and the fierce competition in the market require printing to develop faster, better and cheaper. When prepress and printing are digitalized, intelligent and networked, post press processing has become a bottleneck restricting the rapid development of the printing industry, such as magazine printing and catalog printing. Customers hope to carry out high-speed and high-quality packaging without increasing costs or at a lower cost. This trend is determined by the rapidity, personalization and targeting of customer requirements, and is also the thunder of market competition. For other printing units, speed has become the basis of competition. Quality is the guarantee of competition and the key to ensure the long-term development of post press processing industry. However, the traditional post press processing speed and quality are not satisfactory. Therefore, the development of the whole printing industry is of great significance when the post press processing automation and intelligence are developed

I. automation of post press processing

the focus of post press processing automation is to use high-tech and advanced practical technology to transform and improve paperback binding linkage machine/linkage line, hardcover linkage machine/linkage line, die-cutting machine, paper cutting machine, etc. Improve its automation, intelligence and linkage level, ensure the stability and reliability of quality, and improve quality and efficiency. Intelligent equipment must be equipped with intelligent system. In order to make the post press processing flow smooth, it is necessary to eliminate the barriers between various processes, strengthen integration, shorten the cycle and extend the field. Today, post press processing has been extended to the mailing part, that is, post press processing is responsible for all mailing information, from address inkjet or labeling to sorting and packaging before sending to the postal department. These sorting and delivery technologies shorten the time for the printed matter to leave the printing machine. If the printed matter can be prepared and processed directly, the work cycle will be greatly shortened

in recent years, many units have invested a lot of money in prepress, printing and printing, and achieved gratifying benefits. However, for the units that have little or no investment in post press processing, they can only get a small output and increase the cost. It is necessary to pay more attention to the post press processing, such as the application of post press processing automation technology. First, the automation of post press processing can save money. Most of the equipment has the function of automatic adjustment instead of manual labor. As long as the operator adjusts several buttons on the console, he can control the folding, binding or sewing, hot stamping, film covering, cutting and other processes. These generally require new and advanced machinery and equipment. For example, the new folding machine has a zero adjustment function to automatically adjust the bending. This function enables the operator to fine tune the printing plate as long as the knob is turned, instead of removing the cylinder as before (at least two talents). The numerical control of the console saves a lot of time. At present, the automation and intelligent control level of die-cutting machine, paper cutting machine, horse riding stapler and other equipment is continuously improving, such as data communication between multiple programmable controllers of die-cutting machine, LCD intelligent operation display screen, man-machine dialogue; The optical fiber sensor is used to detect the cursor, accurately position, digitally servo, and control the surface tension of holographic aluminum foil

hot stamping hologram is used to imitating foreign products, machinery and precision manufacturing technology for a long time, so it still lags behind the advanced level. For example, the cutting speed of the paper cutter, large color screen display, image menu, multi language selection, fault display, automatic paper loading and unloading and other functions have been greatly improved. The automation and intelligent control level of high-grade paperback linkage machine, high-grade hardcover linkage machine, high-grade box pasting machine, bag making machine, high-grade polishing machine, circular die cutting machine, high-grade slitting machine, carton production line, dry and wet compounding machine, ticket production line and other equipment has also developed to a corresponding level. Some manufacturers such as Heidelberg and Manroland have put their products into the market. Appearance packaging is also seen as a good way to save money, but a coherent workflow also achieves the goal. Current third-party systems, such as QTI products, allow printing to be controlled on a console, including binding. In order to improve efficiency, the future workflow includes all printing processes. CIP3 was born for this reason. CIP3 system is based on international standards. This international standard is called the integrated collaboration of prepress, printing and post printing. CIP3 means that the new national standard is basically based on the standard GB8624 (2) 006, which shortens the preparation time of operations. It was initiated by Heidelberg and has been supported by 33 manufacturers and a printer

CIP3 has been applied in prepress and printing fields, such as adjusting ink volume and controlling color. At present, comput of polar, stahlfolderompufold and Yuru Yucheng navigator of MBO all support this system. As for the next generation standard CIP4, it includes all the features of CIP3 plus Adobe's standard file format JDF. In addition to printing information, CIP4 also includes the entire workflow and the description of characteristics on different platforms. This can control process variables and improve quality

the cutting machine illustrates the development trend of ergonomics. The development of the linkage, digitalization and intelligence of the cutting system will greatly reduce the operation time and improve the quality. It is estimated that its comprehensive efficiency is more than 2001 that of an ordinary single cutting machine, and can reduce the overall cost and stabilize the operation. The paper adjustment equipment, such as stacker, paper Collider and waste collection system, can reduce the operation time and improve the control accuracy. The goal of the cutting system is to improve efficiency and reduce labor intensity

movable paper feeder currently popular in Europe, The paper feeding mechanism can be transferred from the printing press to other processes (for example, in the folding machine, it is not necessary to reload the paper on the folding machine, which can save time and reduce labor intensity.

II. Diversification of post press processing

in the development of intelligent post press processing, diversified post press processing is also an important issue. Printers strive to provide consumers with more effective processes and equipment, and so are post press processors. In recent years, many post press processors The process of UV glazing, film covering, folding/gluing, and even the printing operation in the post press processing are added, which enhances the competitiveness of the post press processing. For example, rotary bronzing and embossing printing have opened up new markets. At present, rotary bronzing mainly includes narrow web rotary bronzing and sheet fed rotary bronzing. Narrow web rotary bronzing is a bronzing unit used in gravure press. With the development of bronzing technology and the improvement of speed. Gravure printing machine has been able to produce at high speed at low cost. The market for narrow web rotary bronzing is very broad, especially for real-time printing, such as trademark and cartoon printing. Large quantities of trademarks can be integrated into decorative processes such as bronzing and embossing in narrow width printing, which hardly needs to increase the cost. Bronzing and embossing are no longer expensive for consumers who need to increase the volume of printed products. Narrow roll; Cylinder paper rotary bronzing has opened up the market and attracted more attention. At the same time, it also poses a threat to sheet fed printing (such as the trademark printing of wine). However, the development of bronzing and embossing will be conducive to the development of the printing market. Sheet fed rotary bronzing uses the curve die on the drum. Although it does not complete printing and bronzing like narrow web rotary bronzing, it is still faster than standard pattern printing. This is very beneficial to the mass production of cartoon pictures, greeting cards, book cases and other similar items. The more mature and well-known the process is, the faster the business rises, and the more favorable the position of post press processing will be

III. on demand post press processing

with the extensive development of on-demand printing, on-demand post press processing will also become a supporting process for the future development of intelligent printing 10 ⑴ 5 years later. Now the binding equipment has a new change. Personalized direct mail and variable printing account for an increasing proportion. Although there is still a long way to go for personalization of all elements, graphics and text, and layout, now some devices have realized personalization. For the problems of sea lines and broken lines, the devices provide personalized inkjet output. Resolution of each. The sheets were printed with different addresses and even different designs. Bu FM Zhang prints are different, bookbinders have encountered new problems

how to solve the waste of different printing sheets? At present, there is no efficient solution. Manufacturers have tried many methods, such as printing marks on the printing sheets. Current solutions work well, but are expensive. Heidelberg has provided the equipment nExpress for personalized printing, a new type of printing machine that can print single sheets. Both poler and Heidelberg's stack folding machines provide solutions for personalized printing to process nExpress products. On demand printing (POD) emphasizes flexible, personalized and short edition printing. Pod printers can usually complete the printing of products within 24 hours

nowadays, the binding equipment for short edition black-and-white soft cover books and periodicals has become very complex. Many suppliers have provided another automated or off-line solution for the binding of small quantities of paperback books and periodicals. This new equipment is equipped with a Book sealing machine and a new generation of highly automated three side cutting machine. The binding device can be adjusted according to different spine thicknesses, and is suitable for on-demand printing. There is a large market for short version mail advertisements. Many digital printers use program binding machines to produce hardcover books and periodicals. The complexity of binding equipment, the limitation of the decoration of short hardcover books and periodicals, and the limited technology and experience create opportunities for the program binding machine. At the same time, because of the flexibility of short edition printing, many program binding machines have been oriented to print short edition book blocks to meet customer needs. In the past three years, the printing industry has been committed to establishing pre press, printing and post press communication standards. Although CIP3 originated from prepress and ink equipment, it has begun to have a certain impact on post press. The multi-functional digital printing machine emphasizes personalization. For example, two-color and multi-color printing require a high degree of consistency in the information transmission of each production process. Sheet fed integration technology is turning to the publishing market. At present, several standards have been formed to ensure the accuracy of page numbers of complex texts and the consistency of documents

in a word, with the wide application of digitalization, networking and intelligence in the field of printing and post press processing, it will add wings to the rapid development of the printing industry. It can be asserted that the intelligent technology with high-tech content will lead the trend of the printing industry in the future
