Digitalization and informatization of the hottest

  • Detail

Digitalization and informatization of the printing industry in recent years, breakthroughs in the field of printing technology have been made in many ways, the most prominent of which should be JDF based open workflow solutions suitable for different application fields, The overall solution of digital printing directly applying this technology is based on the digital printing system characterized by digital imaging technology and variable information printing, and the digital printing technology based on the combination of digital prepress system and traditional printing (the combination of CTP technology and traditional printing equipment)


JDF based workflow solutions suitable for different application fields, such as Yintong workflow management system launched by Heidelberg. Yintong's internal software is based on JDF. Those JDF based products, such as Yintong yinyide system, and products with JDF interface extensions, such as prime and Prince management software, can be integrated into the new workflow. The Changliu digital workflow management system launched by Founder group of Peking University adopts PDF as the internal file format and JDF industrial standard format as the electronic workflow voucher to transmit the operation parameters in the whole process. With VA as the research platform, through the perfect workflow processing plan and workflow voucher processor, it can be easily and automatically completed at high speed, including standardized processing, prepress pre inspection, trapping, color management, screen preview, folding Make up, digital proofing, film or printing plate output, ink control output, automatic archive control, J0f information import and export, remote version transfer and other tasks. Creo launched a full set of Chinese workflow management system, including PRINERGY yinnengjie workflow, PRINERGY Evo yinnengjie evolution workflow and preps mosaic software. The system provides a complete set of workflow management tools for page processing, proofing, film and direct plate making output, and includes a powerful database. The highly sinicized system is customized for China's printing industry

any printing can constitute a process, but how to effectively build and implement it is the key to the profits of printing manufacturers. Those specially developed and modulated workflow solutions enable printing manufacturers to find a way to make profits while seeing that printing ultimately depends on digital solutions. Of course, the construction of digital workflow needs a higher information environment, and the threshold is not low. How far are Chinese printing enterprises from digital workflow? Many enterprises began to seriously think about this issue

II. Digital printing system

according to the impact resistance test requirements in 26.4.2 of GB 3836.1 (2) 010 and the problems encountered in ordinary experiments, such as the impact of the hammer head is too large, the drop hammer tube is too large and the prototype (sample block) enters the tube, there are more than 30 top digital printing enterprises around the world. Including major enterprises in the digital printing industry such as Kodak Wanyin, Kodak nExpress, Fuji Xerox, Saikang Xeikon, EFI, OCE, HP indigo, Scite, etc. Its digital printing system includes the application of optical imaging, inkjet imaging, electrocoagulation imaging, magnetic recording imaging and other imaging technologies, as well as various types of digital printing equipment and digital production overall solutions using dry toner and wet toner as raw materials

although the printing quality and speed of digital printing system have been greatly improved, it is developing towards high-speed, high-quality, wide width and automation. However, at present, traditional printing cannot be replaced in some fields, mainly in high-quality printing and batch printing speed, so its main application fields are: commercial Express Printing, organ printing, finance, telecommunications, postal service, insurance, small batch publishing and printing, packaging labels, card printing and other fields with high requirements for variable data printing

at the same time, another development of digital printing system has shifted from display technology to market application. In the fields of commercial personalized printing, label printing, anti-counterfeiting printing, all kinds of professional ticket printing, bar code and variable data printing and traditional printing, digital printing takes the lead with its advantage of high efficiency in processing information. Digital printing is not only changing the pattern of the printing market, but also constantly opening up and creating new market space, bringing a new printing concept to the printing industry - printing is information service, and the era of digitalization and informatization of the printing industry has begun to come


CTP technology has become mature and perfect, and has entered the industrialization stage. For example, the heat-sensitive printing plate without treatment, purple laser CTP, ultraviolet exposed CTCP and super large format CTP version compete with each other, leading the way. Creo's flagship brand of CTP equipment, trendsetter, is a model in terms of quality, efficiency and reliability by using square dot thermal imaging. Screen company's "Thunderbolt publishing God" series CTP can meet the requirements of printing format and output speed of different plates of a variety of printing machines. Chemical free treatment of CTP plates is the development direction, and the xcalibur45 plate making machine of AGFA and Azura chemical free washing thermal plates have become highlights. Azura plates can be printed on the machine only after being washed with water and glued after being sensitized, so as to ensure stable quality and meet environmental protection requirements. Sublima brilliance point can be realized on CTP, which means 3401pi printing can be easily realized. This technology is also quite eye-catching. In recent years, violet laser CTP has developed rapidly. Its advantages are low laser price, long service life, high sensitivity, fast imaging speed, and polymer polymer plate technology has also matured. Compared with thermal and UV laser technology, CTCP is very competitive in plate making quality and efficiency. 10. The detection of pedal force needs to be carried out under the ventilation state of the brake valve, which has the advantage of low cost, and can better complete the conflict free transition and connection from analog to digital, which undoubtedly opens up a new field of CTP application. I'm afraid that the market can only decide whether thermosensitive, violet laser or CTCP is superior or inferior. To buy quality or pursue low cost, users can have different focuses, but customers are more looking forward to having both fish and bear's paw

IV. printing equipment

improving production capacity and added value, improving quality, and reducing consumable energy consumption and operating costs are the eternal theme of printing technology. In order to achieve this goal, the integration of production and digital workflow has begun to take the stage. In the concept of integrated production, printing equipment is no longer an isolated equipment in the traditional concept, but a node of the whole production network system. It must be able to accept and implement the instructions of open standardization, complete the automatic presetting of equipment, and be able to monitor, adjust and manage in real time. Therefore, the equipment itself must be a highly automated and open system. As a configuration to improve the automation and intelligence of the system, such as automatic plate replacement, automatic drum cleaning, automatic ink control system, automatic overprint system, programmable intelligent board, etc., its role is more prominent. Taking the standard module as a unit, it can be flexibly configured to form a system, which can be successfully connected with the digital workflow, The traditional printing equipment, which has become the mainstream of printing machine design, is still developing in the direction of multi-color, multi specification format, adapting to a variety of grams of thin and thick paper, connecting lines, and reducing auxiliary operation time (downtime). Five color, six color and eight color units with different configurations can complete full-color + spot color (including metal ink) + variable information +uv glazing at one time, and double-sided full-color printing, large format printing, printing + die-cutting, printing + binding line printing and other equipment continue to appear brilliantly, which is dizzying

highly intelligent configuration makes its operation very agile. The application of shaftless (electronic shaft), seamless, inkless keys and sleeve technology will bring revolutionary changes to the development of printing machines. Shaftless (electronic shaft) drive, that is, real-time independent drive technology, can not only eliminate the error of mechanical transmission, simplify the mechanical transmission structure, and facilitate the modular design, but also make the variable adjustment of the drum arrangement structure and the variable diameter adjustment of the drum possible (this is also the dream of the printer designer). Combined with seamless sleeve technology, it can realize zero reactive printing, zero loss of pressure and vibration printing, and adapt to a variety of formats, a variety of wire cutting sizes, a variety of grams of paper, and a variety of printing materials. It will also make the currently relatively quiet in-machine direct plate making technology (D1) have a new place to play (it is very simple to transplant in-machine direct plate making to sleeve direct plate making)

shaftless drive and sleeve technology have been widely used in wheel machines. Manroland, KBA and Goss all have various models of shaftless drive wheel machine series. It is noteworthy that beiren nt3145 and nt3175 tower printing machines developed by beiren group, a domestic enterprise, have adopted shaftless drive technology, indicating that domestic printing machine enterprises have made progress in the application of this technology

in the sheet fed printing machine, the shaftless technology has also been applied. The plate cylinder on the Manroland 700 is directly driven by an independent motor, while other cylinders still adopt the conventional driving mode. In this way, the unit operation can be flexibly adjusted, and the plate can be changed independently. However, there are few shaftless prototypes with variable diameter seamless sleeve technology. It can be seen that there are still many technical difficulties to break through and solve to truly realize the new concept of variable structure and variable diameter. However, there is no doubt about this development trend of printing machine
