Postpress technology keeps pace

Editor's note:

Compared with the new trends in the printing industry, one-sided printing, rapid printing, and on-demand printing, labor-intensive post-press processing is even more backward. Some people saw postpress as a bottleneck in the printing industry. With the improvement of post-press automation, technological innovation has become more and more important in a rapidly developing society. From the Drpa 2000, we can see that the speed of post-press processing and finishing machinery has been greatly improved, and the accuracy and stability have also been improved to varying degrees. After printing on demand, J has started to surface. In this China Print 2001 exhibition, you can see the post-press processing and finishing in various technology companies such as cutting equipment, perfect binder, folding machine, collating machine and gilding die cutting machine manufacturer. The status and development of technology. Whether it is a foreign multinational company or a leading company based in China, you will see a colorful and rapid development of the post-press stage.



When we discuss the popular technologies such as CTP and digital printing, we must not ignore the important printing and finishing of the printing industry. The professional and perfect finishing work clearly affects the quality of high-speed, fine prints, and thus affects the overall rapid development of the printing industry.



Druna 2000 shows the world the latest technology, the latest technology and the latest equipment in all areas covered by the printing industry. The author will integrate the views and practical techniques of many experts in the field of postpress processing, and look into the development trend of the post-printing process to break the seal. After the concept and technical constraints, the development of our country's post-printing process will help.



In terms of post-press processing technology, in actual work, whether it is to treat paper cutting, folding, adhesive or any process of punching and binding, book binders and case printers. Publishers and post-press service providers all regard the highest precision as their own goal; the processing speed follows the development of printing, and the processing format also follows the format of the printing press, with no major changes. Taking the book binding equipment as an example, the book binding equipment is mainly based on riding horses, plastics, and sewing threads. There are no breakthroughs in its principle, structure, and functions, and there are further improvements in quality assurance, ease of operation, and reliability. The improvement. The requirements for the absolute speed of the equipment in the binding plant are the requirements for the speed of change in the direction of change. Both Martini in Switzerland and Heidelberg in Germany have launched new products. The operating procedures and adjustments of the equipment in the rubber factories are more and more convenient. Martini, Heidelberg, Kolbs, and Warrenberg each have their merits; hot melt glue binding has become a rising star of book binding. The highest speed for the sewing thread is 200 sticks per minute, automatic manning, automatic delivery, very delicate. With the increase in the degree of automation and speed of these devices, the overall need is to adopt modern electronic technologies such as touch-screen human-machine interface technology, PLC, PCC technology and variable-frequency adjustment systems, and various types of sensors in control operations.



Everyone agrees with this view. The future development trend is to minimize the time spent through a short process flow, making it possible to increase the speed of operation. As a result, the trend of post-press processing is becoming more and more of a short version. Therefore, it is also increasingly required to shorten the binding time in order to effectively improve and improve the economic efficiency. Bauer Group, William Group, Heidelberg Postpress Business Unit Many manufacturers have introduced high-quality solutions to customers and have integrated various processes into their efforts. I believe that through this exhibition, this concept will be more deeply rooted.



Digital printing technology has promoted the development of the "print on demand" market. Now, "Finish on Demand"

It began to enter the people's field of vision. Many well-known manufacturers have already launched post-press processing and printing integrated products based on the "on demand" concept, such as On-Demand Machine, Duplo, Roll Systems, Rosback, etc. Expansion, perhaps integrating on-demand printing, will make the division of labor between printing and packaging companies less obvious.



In terms of finishing after finishing, the integrity and automation of the process have been greatly developed, and can be reflected in the automatic production lines of glazing, laminating, bronzing, die cutting, tying and gluing.



BOBST is one of the largest groups in post-press processing and packaging machinery. Its automatic die-cutting and creasing machine has a speed of 12,000 sheets/hour. It is a new concept model representing the highest level in the world today. The novel design uses computer control. In addition Steuer's company has a holographic hot stamping machine with a round, circular, sheet-fed automatic hot stamping machine. Kurz's web automatic round hot stamping machine with holographic hot stamping function can increase the speed and precision of poor printing again, and reduce costs in large quantities. The general development trend of automatic folding folder gluer is high speed, multi-function and Packing and packing automation. BOBST's MEDIA 1O0IIIA-2 is one of the instructions.



In contrast, the printing press companies in China have developed rapidly in recent years, but there is a certain gap between the most advanced equipment and the international level. Shanghai Ziguang and Shanghai Yahua continuously improved their technology and continuously expanded their export markets. More companies should use ChinaPrint 2001 as an opportunity to seize opportunities and accelerate development.



Post-press processing and finishing will develop towards humanization, automation and high-efficiency. Printed products will be more exquisite and machines will be more stable. Under the centralized control of computer systems, automated printing, processing, and packaging production lines will become mainstream. product.
